Understanding breast cancer
Breast cancer forms in the cells of the breast and is the most common cancer in women, though men can develop it too. Most cases are found early, when treatment works best.
Signs and symptoms
Possible signs include a new lump in the breast or underarm, swelling or thickening, dimpling or skin changes, nipple changes or discharge, or breast pain. Many breast changes are not cancer, but new ones should be checked. Learn more about the signs of breast cancer.
Lowering the risk
Risk can be lowered by staying physically active, keeping a healthy weight, limiting alcohol, and, for some, discussing risk-reducing options with a doctor. Knowing your family history matters, since some breast cancers are inherited.
Finding it early
Mammograms can find breast cancer before it can be felt, which is why regular screening is recommended for women at average risk starting in their 40s. A diagnosis is confirmed with a biopsy. See our guide to screening and early detection.
Why stories like this matter
When a public figure shares a cancer diagnosis, it can prompt others to learn the warning signs, talk with their doctor, and take screening seriously. That awareness saves lives — a cancer found early is very often far more treatable.
