Same here, I was 68 y.o. when diagnosed in February. I was Gleason 7 (3+4). I started ADT (Orgovyx) on March 26, SBRT from April 9 to 21 (without SpaceOAR). I noticed some white mucus and a little blood on my stool about 4 days in week 2 post-radiation; I notice no more in week 3. Heard that risk of rectal damage could have been reduced substantially (not 100% eliminated) if there was a spacer.
My oncologist mentioned that my immediate side effects would occur around the 3rd or 4th week after my last SBRT. I am cautiously optimistic for this coming week, when my wife and I will be on a Disney Cruise (booked 8 months before my diagnosis). My oncologist said that I'm good to go; I hope if my SEs peak on week 4, they wouldn't be much worse than week 2. (The long-term SEs may be 10 years or more down the road; not worried about them yet--new treatments may be available by the time they appear, if ever.)
My oncologist will advise if I can get off Orgovyx after 8 or 12 months. I am just a month and a half now.
