Breast cancer in men
Although it is rare, men can get breast cancer. About one out of every 100 breast cancers diagnosed in the United States is found in a man. Some men inherit abnormal (mutated) genes from their parents that increase the risk of breast cancer. Mutations in one of several genes, especially a gene called BRCA2, put you at greater risk of developing breast and prostate cancers.
Men who have a strong family history of cancer should discuss this with their doctors. Black males have the highest incidence of breast cancer among males.
The most common kinds of breast cancer in men are the same kinds in women:
- Invasive ductal carcinoma. The cancer cells begin in the ducts and then grow outside the ducts into other parts of the breast tissue. Invasive cancer cells can also spread, or metastasize, to other parts of the body.
- Invasive lobular carcinoma. Cancer cells begin in the lobules and then spread from the lobules to the breast tissues that are close by. These invasive cancer cells can also spread to other parts of the body.
- Ductal carcinoma in situ (DCIS) is a breast disease that may lead to invasive breast cancer. The cancer cells are only in the lining of the ducts and have not spread to other tissues in the breast.
