Possible environmental factors that may contribute to an increase in breast cancer include use of lawn services, dry cleaning, and pesticide use.
- 30% of women in high-incidence of reported breast cancer areas reported high routine use of pesticides, compared with 23% in low-incidence areas.
- 36% of women in high incidence of reported breast cancer areas reported use of flea and tick products, compared with 42% in low-incidence areas, a pattern in contrast to results on use of other chemical products.
- 17% of women in high-incidence breast cancer areas reported using termite treatments in their homes, compared with 9% in the low-incidence areas.
- 65% of women in high-incidence areas of breast cancer reported using professional lawn service compared with 36% in low-incidence areas.
Many pesticides contain endocrine disrupting compounds (EDCs) that mimic our natural hormones. Exposure to EDCs is an emerging area of study for breast cancer risk. Since a woman's lifetime exposure to natural estrogen is linked to higher breast cancer risk, exposure to compounds that mimic estrogen and other hormones may also increase risk.
Cancer is caused by external factors (chemicals, radiation, and viruses) and internal factors (hormones, immune conditions, and inherited mutations). (ACS)
Environmental factors, defined broadly to include smoking, diet, and infectious diseases as well as chemicals and radiation, cause an estimated three-quarters of all cancer deaths in the United States. (ACS)
Radon exposure in homes can increase lung cancer risk, and cigarette smoking greatly increases the effect of radon exposure in lung cancer risk. (ACS)
Ten or more years may pass between exposures or mutations and detectable cancer. (ACS)
Exposure to sunlight (UV radiation) causes almost all cases of basal and squamous cell skin cancer and is a major cause of skin melanoma. (ACS)
Various chemicals (benzene, asbestos, vinyl chloride, arsenic, and aflatoxin for example) show definite evidence of causing cancer in humans. (ACS)
The following chemicals are considered probable human carcinogens based on evidence from animal experiments; chloroform, dichlorodiphenyl-trichloroethane (DDT), formaldehyde, polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons. (ACS)
Many kinds of pesticides (insecticides, herbicides, etc.) are widely used in agriculture in the production of the food supply. High doses of some of these chemicals have been shown to cause cancer in animals. (ACS)
During the past 50 years the United States has allowed Arsenic, a known cancer causing element, to be present in its drinking water in amounts that are FIVE times higher than the levels recommended by the World Health Organization.
