Radiation therapy is a highly targeted, highly effective way to destroy cancer cells that may linger after surgery. This reduces the risk of recurrence.
Radiation is usually given after mastectomy in men with:
large cancers (5 centimeters or bigger)
a positive margin of resection (when the cancer comes very close to or is at the edge of the breast tissue removed)
a significant area of lymphatic or blood vessel involvement
significant lymph node involvement (four or more positive nodes)
After mastectomy, radiation therapy is usually given 5 days a week for about 5-7 weeks.
Radiation can also be used for men with advanced (metastatic) disease to relieve symptoms or help avoid complications from specific areas of spread. For example, radiation can help relieve painful bone metastases, decrease the risk of breaking a bone that's been weakened by cancer, decrease bleeding from skin involvement, and reduce neurological symptoms if the cancer puts pressure on nerves or the spinal cord.
Definition A magnetic resonance imaging (MRI) scan of the chest is a noninvasive imaging method that uses powerful magnets and radio waves to create detailed pictures of the chest (thoracic) area. Unlike x-rays and computed tomographic ( CT ) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the Earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals. Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images.

When we live with pain on a daily basis, we often wonder if a new pain is something we should be concerned about. It can be particularly difficult to tell if you have a condition like fibromyalgia, where the pain typically moves around from day to day. Right or wrong, most of us wait to see if the pain gets worse before getting it checked out. But when it's chest pain, we naturally wonder if we could be having a heart attack. Heart Attack Symptoms So how do we know when chest pain is something to worry about? Following are signs that can indicate a possible heart attack: • Uncomfortable pain, pressure, squeezing or fullness in the center of the chest that lasts more than a few minutes. • Discomfort that spreads to other areas of the upper body including the back, neck, jaw, stomach, shoulders, or one or both arms. • Shortness of breath. • Sweating, anxiety, nausea, or lightheadedness. • A feel...
