WASHINGTON, Dec. 11 (UPI) — Estrogens, used in
hormone-replacement therapy and contained in birth-control pills, have been
added to the list of known human carcinogens, a U.S. government report revealed
Wednesday.
The report, sent to Congress every two years, lists a total of
new 15 substances categorized as “reasonably anticipated” to increase the risk
of cancer. The list totals 228 items.
This 10th edition of the report was prepared by the
National Toxicology Program, a branch of the Department of Health and Human
Services at the National Institute of Environmental Health Sciences, one of the
National Institutes of Health. Three panels of government and non-government
scientists reached their conclusions after reviewing medical literature and data
on various substances. Much of data reviewed included animals studies that had
linked these substances to increased risks of cancer. [Full story]
