Thanks td,
I wish you well in your Brachy course and hope the side effects clear up soon after completion. I used to suffer from Ulcerative Colitis in the seventies through to the nineties so I know what it's like to have a need of a bathroom in a hurry.
I was offered Brachy and RT but interestingly they were the other way around. HDSR followed by fifteen fractions of RT or twenty fractions of RT. I opted for the latter as I reckoned that by the time I'd driven the fifty mile round trip every day for three weeks I might have got used it and one more week would be less hassle than a surgical procedure.
Good luck anyway.
