Is good information. But can you talk about the tumours that cannot be treated with tables like imatiniv etc. I have a GIST and i had it removed twice by surgery, i was told my gist did not react to tablets. My question is do gists keeps coming back or will they eventually go. And how many surgeries would i be able to have? Do i have to have surgeries the rest of my life? I was 45 when it was diagnosed and I'm 48 now. It only come to light when it was too big and was obstructing my bowls so i couldn't eat and i was vomiting and diarrea. My stomach hurt like hell if i eat, test were done and have had surgery and it was only found it was a GIST when sent for tests. Thank you for your time.
