Is Male Breast Cancer inherited ?
Male breast cancer is sometimes caused by inherited gene mutations (changes).The genes in cells carry the hereditary information that is received from a persons parents. Hereditary breast cancer makes up about 5% to 10% of all breast cancer. Some mutated genes related to breast cancer are more common in certain ethnic groups. Men who have a mutated gene related to breast cancer have an increased risk of this disease.    There are tests that can detect (find) mutated genes. These genetic tests are sometimes done for members of families with a high risk of cancer.
