These include pain, numbness, headaches, and problems with nerves or hormones. Blood vessels, lymph nodes, or skin masses can be repaired or destroyed.
Radiation is used to try to cure cancer, as well as to treat symptoms.
Radiation treatment with intent to cure delivers a tolerable dose. People who are cured can live healthy lives with no long-term problems. They can be treated again at the same site if a relapse occurs. Almost all cancers require watching out for a return of the cancer. Monitoring may last for 2 to 10 years, depending on the type of cancer.
