Could you tell me what are side effects of radiation therapy in the throat?

Throat related: During tx pain, difficulty swallowing, hoarseness, dry mouth, decreased taste, skin irritation, hair loss, cough. After treatment and long term, stiff neck, difficulty swallowing, change in voice, dry mouth, dental and gingival issues, thyroid damage. The degree and extent of these depends on the amount of neck and throat in treatment field (one side vs both, just vocal cords or larger region).

Soreness: Radiation therapy to the throat can cause numerous side effects both long and short term. In the short term patients can expect hoarseness, difficult and painful swallowing and soreness/redness of the skin. In the long run there can be changes in taste, hypothyroidism, voice changes and swallowing changes as well as long term changes of the skin of the neck.
