Lifestyle Risks for Breast Cancer

The Institute of Medicine’s Committee on Breast Cancer and the Environment issued a report discussing the scientific evidence that documents various risks for breast cancer. The strongest evidence for risk is combined synthetic hormone therapy (especially progestins, not natural progesterone), exposure to X-rays, excessive weight after menopause, and alcohol consumption. Mixed evidence implemented smoking, use of hair dyes, lack of exercise, and exposure to microwaves and other electrical devices. Next in line were second hand smoke, nightshift work, and exposure to various chemicals. The latter has not been well studied. Genetics obviously plays some role as well.
