Radiation therapy uses X-rays several times stronger than those needed for common diagnostic purposes. Both normal and cancer cells are affected, but most normal cells can recover quickly. Cancer cells cannot. Radiation therapy is usually conducted on an out-patient basis, spanning several days or weeks.
Radiation is a localized treatment, just for the area affected by a tumor.
Half of all cancer patients receive radiation therapy. Some cancers can be completely destroyed, while others are reduced in size, making surgical removal or chemotherapy more effective.
