I didn't have similar experience. I had the radio and chemo therapy BEFORE the surgery and the tumor shrunk to 0.1 mm(!) and was removed by TEMS. Now , I'm cancer free but I have all those unpleasant side effects of radiation which damage my digestive system. I wonder how long it will last.Some doctors saying 3-4 years,some don't want to make any predictions and they have no solutions except telling patients like me to take Imodium and drink Metamucil.
