My father had esophagal cancer which was operated, after operation he went through radiation. the radiation dose was 64 Gy, out of which last 24 Gy has been given by hyperfractionated radiation. Followed by that he was treated with intraluminal brachy therapy 10 Gy in 2#(weekly once)
He has tolerated the above treatement well. I want to know for how many days has he to suffer side effects and what are the side effects of this treatment?
