Prevention:

Tamoxifen is approved for breast cancer prevention in women aged 35 and older who are at high risk. Discuss this with your doctor.

Women at very high risk for breast cancer may consider preventive (prophylactic) mastectomy. This is the surgical removal of the breasts before breast cancer is ever diagnosed. Possible candidates include:

• Women who have already had one breast removed due to cancer
• Women with a strong family history of breast cancer
• Women with genes or genetic mutations that raise their risk of breast cancer (such as BRCA1 or BRCA2)

Your doctor may do a total mastectomy to reduce your risk of breast cancer. This may reduce, but does not eliminate the risk of breast cancer.

Many risk factors, such as your genes and family history, cannot be controlled. However, eating a healthy diet and making a few lifestyle changes may reduce your overall chance of getting cancer.

There is still little agreement about whether lifestyle changes can prevent breast cancer. The best advice is to eat a well-balanced diet and avoid focusing on one "cancer-fighting" food. The American Cancer Society's dietary guidelines for cancer prevention recommend that people:

• Choose foods and portion sizes that promote a healthy weight
• Choose whole grains instead of refined grain products
• Eat 5 or more servings of fruits and vegetables each day
• Limit processed and red meat in the diet
• Limit alcohol consumption to one drink per day (women who are at high risk for breast cancer should consider not drinking alcohol at all)
