For more information, visit the Agency for Healthcare Research and Quality for information about medicines to prevent breast cancer and genetic testing for breast cancer.
• Find out the risks and benefits of hormone replacement therapy.^{2 3 5 6 8} Some women use hormone replacement therapy (HRT) to treat the symptoms of menopause. Ask your doctor about the risks and benefits of HRT and find out if hormone replacement therapy is right for you.

• Get screened for breast cancer regularly.¹ By getting the necessary exams, you can increase your chances of finding out early on, if you have breast cancer. For more information about the kinds of tests used to screen for breast cancer, and to learn how you can be screened, see Screening.

How Can I Help Others in My Community?

You can help prevent breast cancer in your community. Get involved in community groups that help friends and neighbors get screened for breast cancer, and reduce their risk by helping them exercise and maintain a healthy weight.

Join your community's Comprehensive Cancer Control program. CDC supports Comprehensive Cancer Control (CCC) programs in all 50 states and many American Indian/Alaska Native tribes and U.S. territories. CCC programs bring together cancer experts, survivors, advocates, and other organizations to plan ways to prevent and control breast and other cancers. For more information, contact your local Comprehensive Cancer Control program.

Increase screening in your community. Giving information to members of your community through newsletters, brochures, and pamphlets is an effective way to increase use of screening services. Research has shown other activities by community groups are effective as well. For more information, see CDC's Guide to Community Preventive Services. For tools, visit Cancer Control P.L.A.N.E.T.

Encourage exercise in your neighborhood. Working with your community to provide better locations for physical activity, such as parks and sidewalks, is an effective way to increase activity. For more information, see CDC's Guide to Community Preventive Services. For tools, visit Cancer Control P.L.A.N.E.T.

Help members of your community maintain a healthy weight. Workplace programs to change diet and promote physical activity have been found to be effective. For more information on community efforts to support a healthy weight, visit CDC's Guide to Community Preventive Services. For tools related to diet and physical activity, visit Cancer Control P.L.A.N.E.T.
