#6. Watch your Weight
Obesity after menopause appears to increase risk of breast cancer. The reverse may be true for premenopausal women.

#7. Exercise
A recent scientific workshop concluded that physical activity provides a small amount of protection against breast cancer. The mechanism of protection is not well understood, however.

#8. Have children before age 30
Reproductive factors influence breast cancer risk through effects on cell growth and division, as well as through promotion of cancer growth. Early onset of menstrual periods (before age 12), late menopause (55 or older), late age at first full-term pregnancy (over 30), and fewer pregnancies all increase breast cancer risk by affecting a woman's hormone levels. Having children before the age of 30 reduces the risk of breast cancer.

#9. Know the relationship between estrogen and breast cancer
Recent use of estrogen replacement therapy has been shown to increase breast cancer risk, with higher risk associated with longer risk. This effect may diminish 5-10 years after the therapy is stopped. It is important that you understand the many benefits of estrogen replacement therapy after menopause, but also know its risks.

#10. Consider tamoxifen (if you are at high risk for breast cancer
Approximately 184,200 new cases of breast cancer are reported each year in the United States, with more than 40,000 deaths. Current evidence supports the offering of tamoxifen (a pill taken for 5 years) to reduce the chances of getting breast cancer in women with at least a 1.67 percent 5-year risk. This drug can reduce the risk of getting breast cancer by about 50%. There are side effects associated with tamoxifen, and these include (among others) hot flashes, increased risk of uterus cancer, and blood clots.
