Male Breast Cancer

Breast cancer may occur in men. It’s usually detected in men who are in their 60s and 70s. According to the National Institutes of Health, breast cancer in men makes up less than 1 percent of all breast cancer cases.

Causes of male breast cancer may include:

  • Radiation exposure
  • Family history of breast cancer
  • High levels of estrogen
  • The BRCA2 gene for breast cancer

Symptoms of cancer of the breast in men include breast pain and tenderness, and one or more breast lumps that you can feel. If you notice a lump or other changes in your breast, see your doctor.

Diagnostic tests for male breast cancer are the same as those for women, but may include an additional test for estrogen and progesterone receptors. If elevated female hormones are found in the cancerous tissue, hormone therapy may be used to stop the cancer from spreading.

Treatment options for male breast cancer are the same as those for women. Your cancer care team will help you decide which cancer treatment or treatments are best for you, based on the stage of the cancer, your general health, and other factors.
