Recently completed my 23 sessions of 2 Gy each - about 2/3 of dose if EBRT was sole therapy. I'm on Lupron for 18 months (6 down), and have brachytherapy in 2 weeks. All in all not too bad for the EBRT - seems it was cumulative within a week and overall. I kept active - climbing 2x a week, lifting 2x a week, and a hike or ski here or there. The biggest pain was having to go in every weekday.
My urinary tract was irritated - but I never had to take the prescribed Flomax, and my bowels were a bit irritated - a bit gassey and cramping, but I never felt like it was a big issue, but was annoying. Only on the last week of treatment did I feel tired enough to miss a couple exercise sessions. Three days after the last session I'm feeling on the upswing. My PSA bumped from .16 to .18 after the process - from irritation and considered stable as interpreted by my medical oncologist. She did note my red blood count was down about 12% - from the radiation - so yea, take a nap!!
I did bake an assortment of 3 dozen biscotti to thank those wonderful radiation nurses. that I gave them after my last treatment :). On to the next phase!!
