Environment and Breast Cancer: Science Review
Soy products contain isoflavones, which are chemically similar to estrogen. Studies investigating a link to breast cancer show mixed results.
MAMMARY CARCINOGENS REVIEW DATABASE Animal studies guide the development of new pharmaceuticals by testing for effectiveness and safety before the drugs are tested in humans. For commercial chemicals and pollutants, animal studies are currently the primary means of identifying carcinogens and guiding exposure reduction to prevent environmental cancers. The Science Review database includes information on 216 chemicals that increased mammary gland tumors in animal studies conducted by the US National Toxicology Program (NTP) or included in the International Agency for Research on Cancer (IARC) Monographs, 11th Report on Carcinogens (11th ROC), Carcinogenic Potency Database (CPDB), or Chemical Carcinogenesis Research Information System (CCRIS) database. For each chemical, the database includes:
- carcinogenic potential
- ability to cause gene mutations
- exposure in the general population and for women at work
- other characteristics of chemical use, sources, and regulation.
