I sympathize with you. Started radiation following my surgery, and I too was desperately hoping to avoid radiation, which comes with nasty side effects. But the doctors would not have recommended it if they felt it would not significantly reduce your odds of recurrence. And I think it’s the same situation for you. It only takes one stray cancer cell to start multiplying and then you have have a recurrence, which means maybe another surgery and then definitely radiation. Recurrence is the worst possible outcome, worse than radiation. I would take the advice of the doctor.
