Researchers from Harvard University, Roswell Park Cancer Institute and the University of Southern California, along with the Silent Spring Institute, collected and assessed existing scientific reports of breast cancer and environmental pollutants, diet, body size, and physical activity. Also reviewed were animal studies that identify chemicals as potential mammary carcinogens. The study findings were released in the online version of the American Cancer Society's scientific journal, Cancer (From Associated Content).
The free, searchable database reveals that exposure to potential breast cancer-causing agents is widespread from chemicals used in consumer products, food, women's workplaces, and in air and water pollution. The database includes references to 900 studies of which 460 are human breast cancer studies. The researchers stressed that 29 of the potential cancer-causing carcinogens are found in massive amounts in the U.S., but little is known yet about their effects on human health.
