My husband 73 years old. had Surgery for oral cancer of cheek, Complete excision, Flap graft from Arm to mouth and then skin graft to Arm from thigh. Negative margins and lymph nodes. We were told to undergo 30-32 Radiation therapy treatments but he does not wish to go through that. I am extremely worried. Can anyone share their experience of this, He feels he can not go through because of pain and permanent side effects
