Hey Jackie, sounds like you have a plan - a good one. I think the docs are right in that PSA doesn’t just stall out; but mine took quite some time (5yrs) to hit the magic .2 and even then it bounced up and down for the last year until finally hitting .18.
I had IGRT radiation, since every day at treatment the machine would do a cone beam scan of my insides to check for gas, stool in the rectum, bladder fullness and relative position of all the organs to each other. Only once in 25 sessions was I kicked off the table for too much gas in the rectum, which is a very critical area.
Still amazed at the technology, even though we always use terms like fried, zapped, cooked, etc to describe what was done. My RO explained that they can actually “shape” the beam to go around the rectum but not thru it; the machine - a Varian TruBeam- actually goes underneath you and radiates you from the back as well….really amazing technology.
