Hi Mark
First time post. I'm 65, I was diagnosed a 3+4 localised about a year ago. I'm fit and active, cycling, gym, swimming etc. Also, I've done Pilates classes for about 10 years, so I'm pretty used to seeing, if not wearing, glamorous Lyrcra outfits. I have just had robotic assisted surgery (RARP) on 15th Jan this year.
The treatment decision totally overwhelmed me, and despite reading every piece of literature given by the NHS nurses, consultants and Prostate Cancer UK, there was no clear favourite that faired better than doing 'nothing' (or active maintenance, depending what your definition of what nothing is). By the way, I assume you have used the Prostate Predict website for comparison purposes. I found it very unhelpful for a 3+4, because at 10 years after diagnosis, it appears everything is virtually the same in that percentage-wise, you're still alive.
Slightly off-topic for you, unfortunately, I have Parkinson's Disease at a relatively early stage which is only kept from progressing by doing exercise. Fortunately though, I like exercise, even in Lycra. But watching my PSA level rise over the months got to me a bit, and I decided it was time to call time on a treatment option. The only modicum of 'proper' help came from the radiologist who said in her experience radiotherapy generally resulted in fatigue for longer than the recovery to full fitness under the robotic surgery. Exercise, therefore was my biggest deciding factor.
I don't know if my recovery is relevant as apparently I'm fairly unique: there aren't any posts involving Parkinson's disease in this forum. Also, I since found out from a nurse after surgery that people with neurodegenerative disorders tend to find recovery from incontinence more difficult, and sometimes never recovery continence at all. This information, if imparted prior to surgery, may have influenced my decision. I've now got an open tap, as it were, and it's actually getting worse since catheter removal nearly 2 weeks ago.
Early days, but I've seen a few posts from people regretting their decision, and I'm tending to think the same for me.
I don't know if this helps, if not sorry!
Best of luck.
