I saw the trailer on TV but had to do a search on CNN to find the story. It basically says that for some older patients there was no benefit to having radiation "therapy" (my quote marks) after surgery. I do note that this is not for everyone!
I am one of the somewhat older patients, and I feel I was forced into rads even though I had only a 6% chance of recurrence. I suffer every day from the effects of the radiation and wish I had never had it.
Now I investigate everything somewhat fanatically every time I need a new procedure or drug.
