SUMMARY A RATIONAL VIEW OF CANCER IN NEW JERSEY
This summary outlines che essential points that are explained in the attached documents.
1. Definitions
o A major distinction is made between mortality and incidence rates. Mortality rates simply represent statistics reported from death certi ficates and provide insufficient data for any solutions; incidence rates are che numbers of new cases/year and relate to Living patients. The status of New Jersey as "the number one cancer state" is based on mortality rates.
o The difference between industrial and environmental cancer is' stressed. Industrial exposures in the "work place" cause a minor number of can cers, and there is an even smaller number attributable to industrial carcinogens that "have escaped into the community" (less than 0.00001* of cancer deaths). Environmental cancer refers to cancers induced by an individual's personal environment which includes cigarette smoking, excess alcohol consumption, "ingestionTof'high~fae/low fibre~dietsr'use, of aicrate/nitrite' containingYmeats, consump'cion^of" foodsTwlch 'artifi-~
['ciiljolors, and other aspects of life-style; the occupational aspects l"df'~the environment are important, but relatively less important.
II. How Cancers Start
o Normal cells have repair mechanisms to undo the damage caused by chemi cal and physical agents. However, these repair systems can be over loaded-
o Cancer-causing agents generally take 20-25 years to produce a cancer. The example of the Hiroshima and Nagasaki survivors is given. ' This 2025 year period is known as the "lag phase" in carcinogenesis,
o Many substances can act together, either in an additive way or synergistlcally (the sum total of the effect Is greater than just additive).
III. The Causes of Human Cancers
UCC 057552
o Specific cancers have been linked with definite agents, but the major
lethal cancers, lung and large bowel, are linked to personal habits.
Only a small percent of cancers are industry-related.
o Nitrites/nicraces and artificial colors are cancer causing chemicals
(nitrites/nitraces are converted into dangerous nicrosamines when
preserved meats are heated), but specific human cancers have not yet
been linked to these substances.
o Life-styles chat include obesity, and multiple pregnancies, are asso
ciated with a greater risk for cancers of the breast and uterus,
respectively.
-r~ .. .. .........
o The most dangerous.human carcinogens^are cigarettes, alcohol, dietary
fats, nitrices/nitrates, and artificial food colors. These are the
most widely distributed in che communities, and are proven co be respon
sible for che larg sc percentage of cancers, estimated as high as SO"
(by Dr. Frank Rauscher, the recenc Director of che National Cancer Inst
cute, and Dr. Theodore Cooper, the recent Assistant Secretary for
Health in HEW).
IV. Specific Problems in New Jersev
o There is a complex array of medical, social, geological and geographic factors that must enter into any analyses and solutions for New Jersey's cancer problems, e.g., the dense urban population in N.J., inadequate educational and medical leadership in the past, etc. The sensitive area of "the quality of medical care in New Jersey" may explain a por tion of the high cancer mortality rates during the period covered by the mortality study.
o New Jersey's unfortunate prominence as the "number one cancer state" is based solely on mortality data from 1950-1969 and does not consider the mobility and shifts in populations from New York City and Philadel phia. These two cities, as well as ocher non-Industrialized urban areas, have death rates as high as Chose of New Jersey. The density of the urban population of New Jersey confounds any analyses of the data available.
V. New Jersey Industry and Cancer
o New Jersey had a 17Z greater death race, for white males, and a 142 greater death rate, for white females, compared to the rest of the country. This is the basis of New Jersey's Infamy,
o Other urban centers, even with light industry, share New Jersey's death rates, e.g.. New York City, its Northern Westchester suburb, its Eastern Nassau suburb, and San Francisco. The state of New Jersey, when com pared to other states, ranks number one. If, however, only populations are compared and state boundaries are Ignored, then New Jersey's races are equal to the rates of urban areas in other parts of the country. The-problem lies however In the fact that even the rural areas of New Jersey have "urban rates"; this is the heart of the problem and requires further study. The answer may be as simple as the face that many New Jersey rural dwellers, who died in 1950-1969, may have been city inhab itants from New York and Philadelphia at some time in the past and carried their damaged cells with them when they moved,
o The types of cancers chat are typically "industry-related" do not account for New Jersey's excess 2,000 cancer deaths each year. All types of cancer deaths are Increased, and in some cases there is a negative correlation (benzene causes lymphomas and leukemias, and benzene is a prominent industrial pollutant - yet, the mortality rates from lymphomas and leukemias are not above the national average),
o Separate studies by Drs. Louria and Demopoulos have suggested thac only 600 of the 14,000 deaths in New Jersey might be "industry-related".
VI. The'List of Carcinogens in S-3035, Section 6
o The list Includes a mix of substances; some are no longer in use, some are not carcinogens, some are strong and others are weak carcino gens. Apparently, at the present time, all are being handled with ade quate precautions.
o Asbestos and vinyl chloride are weak carcinogens. o Research is required to determine permissible exposure levels a3 has
been done with the most powerful carcinogenic agent, x-rays.

A RATIONAL VIEW OF CANCER IN NEW JERSEY
New Jersey has unfortunately achieved infamy because statistics from a National Cancer .nstitute study reveals that New Jersey had the highest mortality rate, per 100,000 general population, in America in the period 1950-1969. This r.eans one of two things: a) if you developed cancer'and lived in New Jersey at that time, you were more likely to die of it because your cancer has been detected at a more advanced stage than in other states, and/or the complicated treatment that was needed was not as available as in other parts of the country; b) the risk of developing a lethal form of cancer was greater in New Jersey than in other states. It is not possible to deter mine which of these two reasons, or what combination- is the truth because reliable incidence data does not exist throughout New Jersey. The data that is available is mortality data, which only shows how many people die each year from cancer. The mortality data, although very inadequate, has triggered massive controversies regarding:
o industry-related cancer o environmental cancer o the personal environment o life-styles and cancer o inadequate health resources o toxic substances o dietary factors o banning of so-called carcinogens o politics o early detection o financial aspects of cancer o possible solutions
Cancer is the most complicated disease process, compared to the other major killers such as heart disease, strokes and accidents. There are over a hundred different forms of cancer, and they start in different organs of the body, in different types of individuals, and under poorly understood circumstances. No other disease process is so intricately interwoven with the very fabric of society; as chough to emphasize their perplexing, intri cate nature, cancer cells remain very similar to the patient's normal cells, thereby frustrating most attempts to "weed" them out.
In order Co put cancer into perspective, so that possible solutions can be evaluated, the major complex aspects must be understood.

DEFINITIONS
Cancer -- a malignant grouch, composed of solid masses o? disorganized cells Chat are ever-grouing, and are capable of spreading co organs far from the original site, e.g., breast cancer stares as a lump, and some of ics component cells will microscopically invade the blood stream which will carry them to the lungs, bones, liver, and brain.
Metastasis - the term U3ed to refer to the spread of cancer cells from its site of origin, to ocher organs.
Early Detection - the process of detecting the cancerous mass while it is still small and therefore less likely to have metastasized.
Radical Surgery - the principal weapon in use today for treating cancer; the surgeon cuts widely around the cancerous mass hoping that none of the cancer cells have microscop'.cally metastasized; the surgeon and other cancer experts generally have no way of .knowing whether an Individual case has already spread microscopically; however, the smaller the original can cer mass, the less likely it is to have spread.
Mortality Rate - the number of people dying as a result of cancer each year; it is generally given as the number of cancer deaths per 100,000 general pop ulation. In America, the average figure is about 170/100,000.
Incidence Rate - the number of new cases that are diagnosed each year, again given per 100,000; in America the average figure Is about 340/100,000; about one-half of this number will eventually die of their disease, but over'a period of 2-8 years; the other half of the newly diagnosed cancer cases will live out a normal life expectancy and die of some other cause.
Industry-Related Cancer - a cancer whose cause can be, at least in part, traced back to a distinct exposure to a chemical or sometimes a physical agent that was present in the "work-place"; this generally encompasses employees and, more rarely, members of their families who are exposed to the employees "contaminated" work cloches.
Environmental Cancer - refers to most cancers, possibly 802; however, the term "environment" is all-encompassing and relates mostly to the personal envirorusent that results from life-styles, habits, and dietary factors; occupa tional exposures, and industry-related events comprise a minor component of "environmental cancer".
Carcinogen - an agent, chemical or physical, that is capable of initiating Irreparable damage to a cell, such that the cell may be untimacely trans formed into a cancer cell.
Co-Carcinogen - a chemical which by itself is incapable of causing cancer, but in combination with small doses of carcinogens (doses too small co cause cancer) will cause the development of cancers.
Epidemiology - the science of studying what disease occurs in which types of people, and under what circumstances - it constitutes medical dececcive work.

II. HOW CANCERS START
Cancer calls are no longer "self-controlled", the way normal calls are. Of the many trillions of cells in our bodies, many of them divide and multiply in order to replace "worn out" cells. Host remarkable is that the normal re placements are exactly like the worn-out ones. Cancers start as a result of some cells losing their normal control mechanisms. This happens as a result of damaging the genetic material and the delicate membranes of a cell bevond repair. It is important to realize that from conception, i.e., when a sperm and egg cell have united to form a unique individual, that single cell and all of its subsequent dividing cells are constantly barraged by damaging agents such as viruses, chemicals, and ionizing radiation. In the overwhelming majority of damaging insults, our cells repair themselves. When repair is inadequate, we see the development of birth defects, cancer, or death. The genetic material of the nucleus, the DNA, has incredible repair machinery, and the membranes of a cell, in spite of their extraordinary delicacy and complexity, are undergoing incessant replacement, 24 hours a day, 365 days a year. In short, evolution has given us resilient cells so that our bodief can take a certain amount of damage. However, the repair systems can be overloaded and some damaging agent3 can specifically attack, the repair systems.
It Is clear that there are certain tolerance limits, and If exceeded, the results may be birth defects, cancer or cell death.
Most cancers are the result of a complex sequence of damaging events .that have not been repaired. However, the damage need not be expressed; there is a need to have other factors.which will "bring out" the cancerous damage. In some instances, li may take 20-25 years to "bring out" the cancerous damage. This is referred to as the "lag phase" and is best exemplified by the survivors of the atomic blasts at Hiroshima and Nagasaki. These large amounts of radia tion caused irreparable damage to cells, but the cancerous nature of the damage was not expressed as a lump of uncontrolled cells until 20-25 years later. In these and a few other instances, there are exposures to a single damaging agent and clear cue blame can be affixed to that agent.
In the overwhelming majority of cancers, there.are multiple agents which Interact and cause cumulative damage. While there are many hundreds of dam aging agents, there are only a few different types of parts in a cell; hence, the same type of cell part may be damaged by several different substances. We can therefore see additive effects, and sometimes synergism, wherein the result is more chan just additive.
III. THE CAUSES OF HUMAN CANCERS
The causes of many cancers are known and are listed below. The numbers In parentheses represent the percent of total cancer deaths caused by that particular type of cancer.
Type of Cancer o lung cancer
(Z of Deaths) (20%)
Causes cigarette smoking*
o mouth cancer
(2%)
cigarette smoking* plus excess alcoholism** plus Inadequate mouth care
o larynx cancer ("voice box")
(1%)
cigarette smoking* plus excess alcoholism**
o esophagus cancer ("food tube")
(5%)
cigaret .e smoking* plus excess alcoholism**
o colon and rectal
(16*)
high dietary fat plus low dietary fibre
o liver cancer (ordinary type)
(0.5%)
excess alcoholism**
o urinary bladder cancer
(5%)
unrestricted use of certain chemicals used in dye production
o mesothelioma
(0.001%)
unrestricted use of asbestos
o hemangiosarcoma (a special type of liver cancer)
(0.001%)
unrestricted use of vinyl chloride
From the preceding list, it is clear that we know what causes over 50% of cancer deaths. There are several major cancer types whose causes are not known and account for a total of 30% of the deaths; these are cancers of the breast, ovaries, pancreas, and prostate. In some of these cancers, we know a spectrum of associated findings that add up to a greater risk, as in cancer of the breast, but this does not mean that a causal factor(s) that can be con trolled has been discovered.
In addition to the above known causes of cancer, the following substances have been identified as potent carcinogens that are consumed In significant quantities (milligrams/day) by the majority of Americans; these substances have not yet been linked as causative factors to a specific type of cancer, as in the case of cigarette smoking and lung cancer, but they are nonetheless
* generally more than one pack/day ** generally oore than three ounces of distilled liquor/day, or more chan
sixteen ounces of wine/day

suspected of causing several different types of cancers. They nay act as co carcinogens, or act synergiscically.
o nitrites/nitrates - are converted to dangerous nitrosamines when preserved neats, such as frankfurters, ham, etc., are heated
artificial food colors - some colors chat are widely used in a multitude of foods and beverages are powerful carcinogens
Some aspects of particular lifestyles are associated with a greater risk for developing cancer and include:
o obesity
associated with breast, colon and rectal cancer
o multiple pregnancies coupled with inadequate gynecologic care
associated with cancer of the 'uterine cervix
o repetitive sun exposure
causes cancer of the skin
Added to all of the above are many ocher agents that are carcinogenic, but they are either weak, sparsely distributed, or not well delineated. This includes:
o hormones used to relieve symptoms of the menopause
associated with cancer of the endometrium
o pharmacologic drugs used to treat high blood pressure
associated with cancers of the breast and colon
o high benzene levels
capable of causing leukemias
o varied organic com pounds in the work place
thought capable of causing cancers of the skin, stomach, liver, lungs and urinary bladder
The conclusion that should be reached at this point is that everyone is exposed to some combination of carcinogenic substances every day and the most significant ones are uncontrolled. Many agents are carcinogenic and there is a desperate need to study and define which of these agents should be brought under more restrictive control. Logic would direct Immediate attention, at this time, to those carcinogens that cause the greatest number of cancer deaths, and are also .widely used. This would result in a list, in order of importance, as follows:
o cigarettes o alcohol o dietary fat and fibre . o nitrites/nitrates o artificial food colors

IV. SPECIFIC PROBLEMS IN NEW JERSEY
The State of New Jersey Is characterized statistically in a number of areas that have a relevance to the high cancer mortality rates, and which may also be involved In the solutions:
o Most densely urbanized population o Lowest average land elevation with respect to sea-level o Highest unemployment rates o Reliance on local water sources of household consumption, in
contradistinction to other states where water sources are not derived from the water table or rivers found in the concentrated urban areas. o Ranks 46th among the states in money spent for higher education per capita. o Until recent years lacked any credible medical schools; Che two existing ones are developmental and reportedly rank 85th and 87th out of the approximate 100 American Schools according to the average scores of the students on the National Medical Board Examinations. o 75% of the interns and residents in the hospitals are foreign medical school graduates; this is the highest in the country; in New York, the second highest, the figure is 50%, while in Cali fornia, this number is 5Z; the reliance on foreigners is directly traceable to the absence of a large enough pool of graduating medical students who have a desire to undertake or continue their training in New Jersey hospitals.
The intermingling of medical, social, geographic, and geological factors listed above, provide clues for analyzing New Jersey's complex cancer problems, and the thought that is required for the solutions. There Is no simple approach. and to highlight this, a critical examination of the New Jersey cancer data is in order.
The National Cancer Institute, under a program directed by Dr. Fraumeni, conducted a nationwide county-by-councy study of cancer death rates per 100,000 general population. This was done by transcribing what was written on the death certificates. The medical records of the patients were not examined. The death rates from 1950-1969 were catalogued from death certificates, and were classified by anatomic site, and sex. Hence, the number of deaths from cancer of the mouth, or of the stomach, in males or females, in Atlantic County, or Essex County, and other such numbers became available. These num bers are interesting, and, in general, there is no county in New Jersey that could be considered "safe" according to these data.
The 1950-1969 mortality study was noc designed by Dr. Fraumeni to provide information for definitive solutions. To employ this type of data for direct ing conclusive solutions is a frank misuse. The study was conducted Co pro vide an overview of the scope of the cancer problem in the nation and nothing more. The reasons that che Fraumeni data of 1950-1969 cannot be used to dir ect any solutions stem from the lack of medical records data such as:
o Size of cancer and extent of disease when the patient was first admitted and diagnosed in the hospital. These two
ucc
057559
factors, size and extent of disease at time of diagnosis, are the principal determinants of the patient's prognosis as to life or death; if the cancer is large, chances are very high that Che cancer cells have already metastasized. o No treatment data is available to judge adequacy of therapy, and of long term, dedicated follow-up. o No patient histories with respect to dangerous habits, nacure of the diet, previous places of residence, occupation, income and educational level.
If the Fraumeni data were to be used for a direct attack on the cancer problem, without any further extensive studies, several false leads would be pursued based simply on mobility and shifting of the population, espec ially in the years from 1950-1969. Miami, Florida has cancer death rates equal to those of New Jersey. With a moment's careful thought, the reason becomes ob' ious - many Miami residents are retired Northeastemers who have come from crjwded urban settings. It is critical to remember that a 20-25 year lag period is required to develop a cancer from the numerous environmental exposures (in cluding cigarettes and alcohol).
Further examination of the N.C.I. mortality studies reveals the following death rates of other urbanized areas and their suburbs.
o New York City o Westchester County (a Northern
suburb of New York City) o Nassau County (an Eastern
suburb of New York City) o Philadelphia o Chicago o St. Louis City, Missouri o San Francisco
215/100,000 200/100,000
212/100,000
221/100,000 206/100,000 220/100,000 206/100,000
Since New Jersey received former dwellers of New York City and Philadelphia during the post-war years of suburban expansion, circumstances in these two cities may ultimately be responsible. Westchester and Nassau Counties may be high in mortality rates for the same reason that New Jersey is, i.e. , the city dwellers led life-styles that predisposed to cancer and when the population shift out of the cities occurred, these individuals carried their irreparably damaged 0NA and altered cell parts with them. If many of these individuals were in the lag phase (20-25 years), this could explain, at least in part, the findings. This is a similar explanation for the high rates in Miami, Florida.
There are many other confounding factors that preclude conclusions, and these are as follows:
o While the population was shifting into the suburbs, including into New Jersey, industry also continued to grow in the state,
o In the 1930*s-1940's (the period of time when people were being exposed in order to develop their cancers and live 20-25 years later in 1950-1969), industry and government were largely ignorant of chemical carcinogens, hence fewer safeguards may have been used in this period.
UCC -7- 057560
V. NEW JERSEY INDUSTRY AND CANCER
Th.e county-by-county death statistics of 1950-1969 are divided by anatomic site and by sex. The overall death races for white males was the highest in the country, but this was not the case for females or non-whites. This can lead to a great deal of speculation, but the data is insufficient for reach ing a solution.
The Fraumeni numbers indicate that the national average death rate from cancer was 174/100,000 (for white maJ.es), while in New Jersey, it was 205/100,000, a 173 Increase. In females, the national average was 130 and, in New Jersey, 148/100,000 about a 143 increase. These are the increases that have precipi tated the current controversy. The increases are significant and were consis tent through the 19 years (1950-1969) of the study. More detailed numbers are presented in appendix A.
Adding to this data are the estimates of the American Cancer Society, regarding N sw Jersey incidences and .mortalities. These are given in appendix B.
The conclusions pertaining Co New Jersey are as fallows:
1. General Findings on New Jersey: Proportionally, New Jersey's figure on cancer mortality is greater than that of any other state in America. Nearly all of New Jersey falls Into the highest decile in the U.S. (top 103) for white males and for white females (Appendix A).
2. Cancer categories in which the mortality, proportional to population,
is higher in New Jersey than in any other state: o Rectal cancer (males and females combined)
The rating of New Jersey as having the worst concentration of mortality from rectal cancer is based largely on the extremely high death rates among both men and women in northern New Jersey, the Trenton-Princeton area included. Thi3 would not be classified as an industry-related cancer by cancer specialists. o Bladder cancer (males only - women not significantly different from the rest of the United States) A proportion of these are industryrelated. o Cancer of the ovary - The mortality figures among the women of New Jersey's northwest comer -- Sussex and Warren Counties -- ranks with the worst in the country. Mortality figures are nearly as high among women in Bergen, Morris,.and Passaic Counties. This causes the mortality figures for women in northern New Jersey in this cancer classification to be worse than for any ocher single concentrated area in the nation. This would not be classified as an industryrelated cancer.
3. Cancer categories in which the mortality races for the state of New Jersey rank approximately with the worst statewide records in the nation:
o Cancer of the large intestine (males and females combined) New Jersey ranks with Rhode Island as the worst in the nation. This is not regarded as industry-related.
ucc 057561 -8-
o Cancer of the Trachea, Bronchus, and Lung - Mortality figures among New Jersey males rank as the highest in the U.S., along with the mortality among males in Louisiana and Florida. A small proportion of these are industry-related.
o 3raast Cancer among females -- The record in this category is worst in New York, with New Jersey, Rhode Island and Massachusetts just behind. This is not classified as industry-related.
4. Cancer categories in which mortality for portions of New Jersey ranks with the worst areas in the nation. o Cancer of the Esophagus (males only) - Northern New Jersey, Connecti cut, New York City, Long Island, and the Greater Philadelphia Area of Pennsylvania, cocLtned, comprise the worst single area in the U.S. for mortality figures in this category. The rate for females in northern New Jersey is above the national average. This is generally caused by a combination of cigarette smoking and excessive alcoholism. In addition, women v*th rare benign esophageal problems are predis posed to cancer of this organ. It is not generally regarded as being Indus try-related. o Cancer of the Larynx (males only) - The highest concentrations of mortality from this type of cancer are in northern New Jersey, New York City, Long Island, the Greater Philadelphia Area and the 'Pittsburgh area. A small proportion of these are industry-related, but generally are caused by a combination of cigarette smoking and excessive alcoholism.
If an attempt is made to correlate the types of cancers that are known to be "industry-related" (l.e., industrial substances contribute together with other factors to the development of cancer), with the types of cancers occur ring in New Jersey, it would be expected that most of the excess cancer deaths in New Jersey would fall into the "industry-related" types - this is not Che case.
There are about 14,000 deaths each year in New Jersey, and about 26,000 new cases each year (from appendix B, estimates for 1974). If New Jersey had average U.S. rates, these numbers would be 12,000 and 22,000, respectively. The excess 2,000 deaths each year and the excess 4,000 new cases each year should fall into the classical "industry-related" categories which include a small portion of cancers of Che:
o Urinary bladder o Respiratory system o Liver o Skin o Lymph organs and bone marrow (lymphomas and leukemias)
Instead, the "excess" 2,000 deaths are spread across all of the anatomic sites in the N.C.I. mortality study (lip, salivary glands, nasopharynx, mouth, esophagus, stomach, large intestine, rectum, liver, pancreas, upper and lower respiratory tracts, breast, uterine cervix, body of uterus, ovaries, prostate, testis, kidneys, urinary bladder, skin, eye, brain, endocrines, bones, and connective tissues). Further, there are some negative correlations, e.g. benzene is reportedly an industrial pollutant in New Jersey and supposedly is
-9ucc 051562
the highest: in the nation, yet the cancer chat should be caused by benzene, such as lymphomas and leukemias, occur at the lower national rates.
o Lymphomas N.J. (White males) U.S. (White males)
o Leukemias N.J. (White males) U.S. (White males)
4.93 4.89 8.74 8.31
Analyses performed by Dr. Donald Louria, Chairman of the Department of Preventive Medicine and Community Health, New .'ersey Medical School, Newark, and presented under the title of "Cancer in New Jersey: An Overview" at the "Seminar for Physicians: Cancer Risk Identification within New Jersey, and Methods of Cancer Control", May 12, 1976, in Cherry Hill, found that only 600 of the 14,000 cancer deaths in New Jersey might, by Industry-related. A different analytic study conducted by Dr. Harr- B. Demopoulos, former Director of the Cancer Institute of New Jersey, also revealed the same types of numbers, i.e., no more chan 600 of the 14,000 cancer deaths could be industry-related, among th deaths reported in 1950-1969; this report was given by Dr. Demopoulos to the "Skevin Coaalttee" in testimony on November 5, 1976.
These two independent analyses therefore indicate that 4.32 of the total cancer deaths in New Jersey could be "industry-related". These percentages ar important and yet it is essencial to realize that these analyses are based on insufficient data and represent the highest possible number of "industryrelated" exposures. This does not mean that industrial pollutants were solely responsible. If an analysis is attempted of how many cancer deaths were caused solely by industrial pollutants, the data Is found to be totally inadequate and very soft estimates yield fractions of IX.
While the cited studies and analyses refer to past events, there is meager data since 1969. The American Cancer Society estimates do not provide sufficient information to answer the ohvious question - are cancer mortality rates and inci dences in New Jersey the same, better, or worse than for the period 1950-1969? Current, but inadequate, "samples" from hospitals that have excellent Tumor Registries indicate chat their cancer case workload has Increased by 502 in the past 5 years, and that the average age of the cancer patient is younger by 5-6 years. This type of data is fragmentary and may reflect changes in referral patterns to some hospitals, or it may indicate a worsening of the New Jersey cancer problems. ' Clear cut answers require far more data.

VI. THE LIST OF CARCINOGENESIS IN BILL .NO. S-3035. SECTION 6
The list includes a mix of substances
o Some are no longer in use, e.g., 4 Aminodiphenyl o Some are not carcinogenic, e,g., alpha naphthylamine - its
carcinogenicity was proven to be due to contamination of alpha naphthylamine o Some are very potent carcinogens, e.g., benzidine o Some are rather weak carcinogens, e.g., asbestos and vinyl chloride o All are currently handled with precautions that lea . to low expo sures of workers such that cancers will not develop.
Asbestos and vinyl chloride are termed weak carcinogens on the basis of careful analyses of the cancers chat they cause. Excessive concerns over asbestos as a carcinogen has been prompted by cases such as that of a 14 year old boy who developed mesothelioma; he apparently was exposed Co this when he was helping his father to smooth down the joints of the newly replaced plaster board walls in their home. Asbestos was in the joint material, not in the plaster board. There was no other known asbestos exposure, and the father did not other wise work with it. Cases such as this are exceedingly rare and form an inade quate data base. Mesothelioma does occur in nature, without asbestos exposure, and it cannot be ascertained whether this 14 year old boy would have been a "Natural" victim, or whether the asbestos was indeed causal. Far more numbers are needed for statistically valid studies in such unusual cases.
The relative weaknesses of asbestos and vinyl chloride are borne out by the fact that workers who were exposed to very large* uncontrolled levels devel oped relatively few cancers as a result. This is in contrast to a powerful car cinogen such as 3,4-dimethyl 4-aminodiphenyl, wherein 15-20% of exposed workers developed urinary bladder cancer in a short lag phase (7-8 years). When the amounts of asbestos, vinyl chloride, and 4-aminodiphenyl are compared, versus the numbers of cancers developed, then asbestos and vinyl chloride are weak carcinogens.
The idea of a comprehensive ban on all carcinogens would lead to the restriction of many activities and substances. Radiation, by x-rays, is the most powerful carcinogenic agent. There are methods for converting physical carcinogens into chemical equivalents, and when this is done, x-rays are quite potent. When the Manhattan Projecc (building the A-Bomb during World War XI) was in full swing, the Department of Pathology at Rochester University was given the job of determining the ill-effects of radiation. There were some individuals who were so impressed by the pathologic changes chat they decreed a "Zero-expo sure". When subsequent, rational studies were done, it was found that small doses of radiation could be tolerated, even chough the effects were cumulative over a life time. This type of exacting research has made it possible to use x-rays for medical use, nuclear plants for energy, etc. The same type of informa tion must be obtained for chemicals.
