Signs and symptoms of breast cancer in men

Men need to know that breast cancer is not limited to only women. Possible symptoms of breast cancer to watch for include:

  • A lump or swelling, which is usually (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 tissue is large enough to be felt.

These changes aren't always caused by cancer. For example, most breast lumps in men are caused by gynecomastia (a harmless enlargement of breast tissue). Still, if you notice any breast changes, you should see your health care professional as soon as possible.
