How is male breast cancer treated?
Male breast cancer is usually treated in the same way as breast cancer in women. However, men are more likely than women to have a mastectomy (surgery to remove the whole breast) rather than a lumpectomy (breast-conserving surgery) to remove the cancer because they have less breast tissue. But some male breast cancers can be treated with a lumpectomy, depending on the size of the cancer, the amount of breast tissue the person has, and other factors.
