What are the symptoms of male breast cancer?

The symptoms of male breast cancer are the same as the symptoms for breast cancer that develops in women.

Any new lump, area of pain, changes in the skin of the breast or chest wall, nipple discharge or inversion (turning in of the nipple), or lumps under the arm or above the collarbone can be symptoms of breast cancer. If a man notices any of these symptoms, he should alert his doctor so that a thorough evaluation can be performed.

In men, the most common symptoms of breast cancer are a change in the look or feel of the breast, a change in the look or feel of the nipple and nipple discharge. Possible signs of breast cancer to watch for in men 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
These changes aren't always caused by cancer. For example, most breast lumps in men are due to gynecomastia (a harmless enlargement of breast tissue). Any breast changes are a reason to speak to your physician.
Male breast cancer symptoms can be similar to those experienced by women and may include:
  • Lumps in the breast, usually painless.
  • Thickening of the breast.
  • Changes to the nipple or breast skin, such as dimpling, puckering or redness.
  • Discharge of fluid from the nipples.
