How common is breast cancer in men?

Men have breast tissue and can develop breast cancer, although it is rare. Men account for only one in every 100 breast cancer cases.

What are the breast cancer risk factors for men?

  • Family history of breast cancer, particularly if a man has inherited a mutation in the BRCA-2 gene
  • Klinefelter’s syndrome (a rare sex chromosome abnormality)
  • Testicular conditions (an undescended testicle, removal of testicles)
  • Age (most cases of male breast cancer occur in men between the ages of 60 & 70)
  • Obesity
  • Chronic liver disease
  • Radiation exposure

What are the signs and symptoms of breast cancer in men?

Breast cancer in men typically presents as a small painless lump in the breast, close to the nipple. Other symptoms may include:

  • Dimpled or puckered breast skin
  • A retracted nipple
  • Breast pain or tenderness
  • Nipple discharge or bleeding

Is treatment for male breast cancer different from the treatment that women get?

Men generally receive the same type of treatment for breast cancer that women do. However, it is standard for men to have a mastectomy rather than a lumpectomy. Men would also commonly receive hormonal therapy since male breast cancer tends to be hormone receptor positive. Radiation and chemotherapy may also be suggested.
