                    There are different types of treatment for men with breast cancer.
                    Different types of treatment are available for men with breast cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment.   For some patients, taking part in a clinical trial may be the best treatment choice. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.   Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. Information about clinical trials is available from the NCI website. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.
                
                
                    Five types of standard treatment are used to treat men with breast cancer:
                    Surgery      Surgery for men with breast cancer is usually a modified radical mastectomy (removal of the breast, many of the lymph nodes under the arm, the lining over the chest muscles, and sometimes part of the chest wall muscles).         Breast-conserving surgery, an operation to remove the cancer but not the breast itself, is also used for some men with breast cancer. A lumpectomy is done to remove the tumor (lump) and a small amount of normal tissue around it. Radiation therapy is given after surgery to kill any cancer cells that are left.          Chemotherapy      Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated.    See Drugs Approved for Breast Cancer for more information.       Hormone therapy      Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working.     See Drugs Approved for Breast Cancer for more information.       Radiation therapy    Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:            -  External radiation therapy uses a machine outside the body to send radiation toward the cancer.     -  Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer.           The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat male breast cancer.        Targeted therapy     Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy is a type of targeted therapy used to treat men with breast cancer.     Monoclonal antibody therapy uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies are also used with chemotherapy as adjuvant therapy (treatment given after surgery to lower the risk that the cancer will come back).      Trastuzumab is a monoclonal antibody that blocks the effects of the growth factor protein HER2.     See Drugs Approved for Breast Cancer for more information.
                
                
                    Treatment for male breast cancer may cause side effects.

		                    Initial Surgery
		                    Treatment for men diagnosed with breast cancer is usually modified radical mastectomy. Breast-conserving surgery with lumpectomy may be used for some men.
		                
		                
		                    Adjuvant Therapy
		                    Therapy given after an operation when cancer cells can no longer be seen is called adjuvant therapy. Even if the doctor removes all the cancer that can be seen at the time of the operation, the patient may be given radiation therapy, chemotherapy, hormone therapy, and/or targeted therapy after surgery, to try to kill any cancer cells that may be left.         -  Node-negative: For men whose cancer is node-negative (cancer has not spread to the lymph nodes), adjuvant therapy should be considered on the same basis as for a woman with breast cancer because there is no evidence that response to therapy is different for men and women.     -  Node-positive: For men whose cancer is node-positive (cancer has spread to the lymph nodes), adjuvant therapy may include the following:                - Chemotherapy plus tamoxifen (to block the effect of estrogen).      - Other hormone therapy.      - Targeted therapy with a monoclonal antibody (trastuzumab).                 These treatments appear to increase survival in men as they do in women. The patients response to hormone therapy depends on whether there are hormone receptors (proteins) in the tumor. Most breast cancers in men have these receptors. Hormone therapy is usually recommended for male breast cancer patients, but it can have many side effects, including hot flashes and impotence (the inability to have an erection adequate for sexual intercourse).
		                
		                
		                    Distant Metastases
		                    Treatment for men with distant metastases (cancer that has spread to other parts of the body) may be hormone therapy, chemotherapy, or both. Hormone therapy may include the following:         -  Orchiectomy (the removal of the testicles to decrease the amount of hormone made).    -  Luteinizing hormone-releasing hormone agonist with or without total androgen blockade (to decrease the the amount of sex hormones made).    -  Tamoxifen for cancer that is estrogen-receptor positive.    -  Progestin (a female hormone made in a laboratory).    -  Aromatase inhibitors (to decrease the amount of estrogen made).        Hormone therapies may be used in sequence (one after the other). Standard chemotherapy regimens may be used if hormone therapy does not work. Men usually respond to therapy in the same way as women who have breast cancer. + CancerGov + Male Breast Cancer
