Vaccines, antibiotic and antiviral medicines, and donated antibodies can help prevent certain infections. Some people need transfusions or medication to make sure they have enough red blood cells or platelets. Gentle massage, yoga, meditation, exercise, and other ways to relax can help you deal with fatigue. Avoid massage in areas that have had focused radiation therapy, have enlarged lymph nodes, or your cancer has affected your lymphatic system. Your doctor will keep checking you for signs of other cancers, too.
