Radiation therapy may be advised after surgery if you have an intermediate- or high-grade cancer or an adenoid cystic carcinoma, if the cancer could not be removed completely, or if the edges of the removed area contain cancer cells. Radiation therapy might be an option as the main treatment if surgery would result in serious problems with eating, speech, or appearance, or for people who refuse surgery.
