well i guess that radiation therapy is different now from when i had it in 2013 i was diagnosed with stage 4 i had alot of chemo and radiation twice a day for 6 weeks every day and it was pretty horrible but what i understand they dont do it like that anymore of course i had my esophagus ,my stomach ,gall bladder,and alot of lymph nodes .They did try to make a pouch like thing for my stomach but it didnt work out but as far as the radiation goes theres alot of pain involved but its not painful recieving it i hope he beats it
