The Department of Health and Human Services added the cancer-fighting drug tamoxifen to the ninth edition of its report on carcinogens. The report, which is prepared every two years by the National Toxicology Program at the National Institute of Environmental Health Sciences, Washington, identifies substances, such as metals, pesticides, drugs and natural and synthetic chemicals, and mixtures and exposure circumstances that are known or are reasonably anticipated to cause cancer and to which a significant number of Americans are exposed.
