Q. What are the long term permanent side effects in my throat from radiation?

A.

Depending on exactly where you receive radiation, a number of side effects can occur either on a temporary, long-term, or delayed basis. They include changes in sensation (the ability to feel), secretions (dry mouth), taste, and range of motion (when tissue hardening restricts movement and posture). These side effects can then affect key physical functions associated with the mouth and throat, such as speech and, especially after radiation, swallowing.

Whether these side effects turn into a chronic condition (or lead to other problems) often depends on how soon they are recognized and treated. Certain precautions such as addressing dental issues, can be taken before treatment begins to reduce—if not outright prevent—long-term side effects. A publication from the National Cancer Institute, Oral Complications of Chemotherapy and Head/Neck Radiation, provides an overview of possible treatment side effects and how to manage them.
