Jennel,

Welcome to the OCF forum. I'm sorry to hear what your father has been going through, but unfortunately, as others have said, the recovery from radiation is a long, slow, painful process. Is he being treated at a comprehensive cancer center? How often is he scheduled for followups with his doctors? (They should still be fairly frequent at this stage, so they can continue to watch for any signs of trouble.)

You mentioned that he isn't doing much for mouthwash. Oral hygiene post-radiation is extremely important to try to fight off infections, and your father should be getting advice from dental professionals that are experienced with the effects of radiation.

Please encourage your father to get on this site also. There are many here who have been through similar experiences and can offer support and advice.
