It's a hard decision made worse by time pressure.

I had radiation treatment 5 days a week for 7 weeks with concurrent chemo. That was about six years ago. I continue to have no evidence of disease.

I do have some relatively minor lingering side effects. A little dry mouth, I have to take thyroid meds and such. All in all a reasonable trade to be free from cancer.

One of the toughest things post treatment was the fear of recurrence. Doing all you can to reduce the chance of recurrence is highly valuable. You may not want to risk being in a situation where you are thinking if only I had done the radiation treatment I wouldn't have had the recurrence.

Again a tough decision, but try to focus on information rather than emotion.

Best of luck.
