Breast Cancer in Men

Although men are less likely to develop breast cancer than women, they do have breast tissue and can therefore develop breast cancer. Types include ductal carcinoma in situ, infiltrating ductal carcinoma, infiltrating lobular carcinoma, Paget disease of the nipple, and inflammatory breast cancer. Risk factors of breast cancer in men include: family history, inherited gene mutations, extra X chromosomes (Klinefelter syndrome), radiation exposure, heavy drinking, liver disease, estrogen treatment, obesity, testicular conditions, and occupational exposure to high temperatures and gasoline fumes. Early detection of breast cancer is usually found in men who have a family history of breast cancer that undergo genetic counseling and testing to detect BRCA mutation. Treatments include surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy. Survival rates of breast cancer in men are high if the cancer is found early and declines in later stages.
