What is Male Breast Cancer?

Though it is rare, men can get breast cancer. Like women, men have breast tissue in which cancer cells can grow. In girls, hormones produced during puberty make the breast tissue grow. Because boys don’t have the same hormones, their breast tissue does not grow like a girl who is going through puberty.

According to the American Cancer Society, breast cancer is about 100 times less common in men than it is in women.

Most breast cancer in men is ductal carcinoma, which means the cancer cells began growing in the (milk) ducts of the breast.

Symptoms of Male Breast Cancer

Like most breast cancer, male breast cancer may be discovered by feeling a lump or noticing a change in the breast shape. Because mammograms are not recommended for men, it’s important that men speak to their physician about any concern with his breast tissue.

Some symptoms of male breast cancer also include:

  • Changes in the breast shape
  • Breast or nipple pain
  • Discharge from the nipple
  • Nipple inversion
  • Swelling of the breast
  • A lump
  • Thickening of the nipple skin
