THE HEAD AND NECK can be affected both by tumors that originate in those areas and the treatment used to destroy the tumors. Even treatment for cancers elsewhere in the body can affect the vital structures and functioning of the head and neck. Because many of the tissues and structures located in the head and neck are growing rapidly during childhood and adolescence, they are very susceptible to damage from treatment for cancer.

This chapter covers damage to bones, teeth, glands, and other tissues in the head and neck. Signs and symptoms are listed, and methods to detect late effects in the head and neck are discussed. Finally, medical management of these late effects is outlined.
