Signs and Symptoms of Breast Cancer in Men
Possible symptoms of breast cancer to watch for include:
- A lump or swelling, which is often (but not always) painless
- Skin dimpling or puckering
- Nipple retraction (turning inward)
- Redness or scaling of the nipple or breast skin
- Discharge from the nipple
Sometimes a breast cancer can spread to lymph nodes under the arm or around the collar bone and cause a lump or swelling there, even before the original tumor in the breast is large enough to be felt.
These changes aren't always caused by cancer, but if you notice any breast changes, you should see a health care professional as soon as possible.
