I was a practicing dentist and opted for surgery for a few reasons - one of them being that surgery was more practical with my schedule.
I took 3 weeks off and then went back to work. Radiation (in my case) would have been many visits an hour or more each way - totally not work friendly.
Ironically, after I retired, I did need 25 sessions of radiation due to a recurrence of the cancer. But since there was no work involved, it was much less stressful than it could have been had I still been employed.
