title: [Male breast cancer].
abstract: Breast cancer is rare in men. Diagnosis of the illness may be delayed due to the fact that the doctor and the patient fail to suspect it. Male breast cancer is treated mainly on the same principles as female breast cancer. A man affected with breast cancer should always be directed to genetic testing, as inherited mutations increasing the risk of developing cancer are more common than in female breast cancer. Most breast cancers in men are hormone receptor positive. Among hormone treatments, the antiestrogen tamoxifen exhibits the best efficacy both in early-state and advanced cases.
