This will lead to an increase in the level of reactive metabolites and result in an increased reaction of these metabolites with intra cellular macromolecules.

The study concluded that asbestos may cause about 5% of all present day lung cancer.12 Inasmuch as lung cancer constitutes about 20% of all cancer, this suggests that asbestos caused lung cancer accounts for about 1% of all cancers---a finding which tends to support most of the estimates shown in Table 11. f Author example, in 1976 a group of government investigators reported on the effects of very low human exposures t o asbestiform fi bers among workers at a gold mine at Lead, Si) 1:1 They re ported a threefold excess in respiratory cancer and suggested that this was due to very low fiber exposures.
