Breast cancer symptoms vary widely — from lumps to swelling to skin changes — and many breast cancers have no obvious symptoms at all. Symptoms that are similar to those of breast cancer may be the result of non-cancerous conditions like infection or a cyst.

Breast self-exam should be part of your monthly health care routine, and you should visit your doctor if you experience breast changes. If you're over 40 or at a high risk for the disease, you should also have an annual mammogram and physical exam by a doctor. The earlier breast cancer is found and diagnosed, the better your chances of beating it.
