It is truly your choice on whether to go with treatment or let it run it's course. I am a 79 year old male who, 10 years ago, was first diagnosed with high grade, non invasive tumors. I have lost count of how many TRUBTs I've had in the last 10 years to remove recurring tumors; plus losing my right kidney, ureter and a small section of my bladder due to cancer. For me... It has been worth the fight! Prayers for your ultimate decision.
