Many factors over the course of a lifetime can influence your breast cancer risk. You can’t change some factors, such as getting older or your family history, but you can help lower your risk of breast cancer by taking care of your health in the following ways—

Keep a healthy weight.

Exercise regularly. 

Don’t drink alcohol, or limit alcoholic drinks.

If you are taking, or have been told to take, hormone replacement therapy  or oral contraceptives  (birth control pills), ask your doctor about the risks and find out if it is right for you.

Breastfeed your children, if possible.

If you have a family history of breast cancer or inherited changes in your BRCA1 and BRCA2 genes, talk to your doctor about other ways to lower your risk.

Staying healthy throughout your life will lower your risk of developing cancer, and improve your chances of surviving cancer if it occurs.
