# cV NOTICE Enclosed you will find a summary listing of tumor rates in the NTP historical control data base as of late March, 1983. All tumors occurring with a frequency of 0.5% or greater are included. This summary will also be published in a future issue of the NTP Technical Bulletin (as may periodic updates). A revised summary listing will be generated approximately every 6-9 months. I hope that this information will be useful to you. V L/.w TI P ) P til CONFIDENTIAL SUBJECT TO PROTECTIVE ORDER.
