Had prostate removed. No cancer in lymph nodes Why are they wanting me to have radiotherapy

Before replying can u give some stats please, it will help.

IE, PSA, Gleeson, MRI report, was cancer contained in gland 

Steve 

PSA 10 . GLEESON 4+3. MRI and  GAMAGRAM were both negative. cells also found in seminal gland.

Maybe because cancer cells found in seminal g. they want to be sure by doing some RT as well, 

My blood test on 25th August, 7 weeks after surgery on July 8th, showed PSA of 0.01.  At my appointment with the Surgeon on September 9th I was told that I would be referred to Oncology Department . I'm still waiting for an appointment with oncology to find out details of RT.

I'm thinking of foregoing RT unless/until the PSA rises.

Any thoughts on that?

Difficult one, I would ask why they want to do RT with PSA ok, is there a particular reason.

Any rise though, Go for RT.

Perhaps their thoughts are belt and braces approach.seminal vesicles outside gland I think so could be the reason. Seminal vesicles may not have been found out until prostate gland taken out and dissected.

Bit of guesswork on the last sentence though 

Steve 

Thank you Steve. I'll stay in touch if that's ok

Anytime, good luck
