Intense treatment for cancers of the head and neck often involves both chemotherapy and radiation. With many important muscles involved in the region, preventing the areas targeted by radiation from weakening can be avoided with swallowing exercises. Ask your oncologist about suitable rehabilitation. The study compared a control group given no swallowing exercises to another group given t...
