External beam radiation

External beam radiation is the usual type of radiation therapy for men with breast cancer. The radiation is focused from a machine outside the body on the area affected by the cancer. This usually includes the chest wall where the breast was removed and, depending on the size and extent of the cancer, may include the underarm area, supraclavicular lymph nodes (nodes above the collarbone) and internal mammary lymph nodes (nodes beneath the breast bone in the center of the chest).

Before your treatments start, the radiation team will take careful measurements to determine the correct angles for aiming the radiation beams and the proper dose of radiation. They will make some ink marks or small tattoos on your skin that they will use as a guide to focus the radiation on the right area. You might want to ask your health care team if these marks will be permanent.

Radiation therapy is much like getting a diagnostic x-ray, but the radiation is more intense. The procedure itself is painless. Each treatment itself lasts only a few minutes, but the setup time − getting you into place for treatment − usually takes longer.
