Other than skin cancer, breast cancer is the most common cancer among American women. For many women, mammograms are the best way to find breast cancer early, when it is easier to treat. Mammograms can find cancer before it is big enough to feel or cause symptoms.

Symptoms

There are different symptoms of breast cancer, and some people have no symptoms at all. Symptoms can include:

• Any change in the size or the shape of the breast.
• Pain in any area of the breast.
• Nipple discharge other than breast milk (including blood).
• A new lump in the breast or underarm.

If you have any signs that worry you, see your doctor right away.

Risk factors

Some main factors that affect your chance of getting breast cancer include:

• Being a woman.
• Being older. Most breast cancers are found in women who are 50 or older.
• Having changes in your BRCA1 or BRCA2 genes.

How to lower your risk

You can do things to help lower your breast cancer risk.

• Keep a healthy weight and be physically active.
• Choose not to drink alcohol, or drink alcohol in moderation.
• If you are taking hormone replacement therapy or birth control pills, ask your doctor about the risks.
• Breastfeed your children, if possible.
