diet and exercise pre prostate cancer prostatectomy

Hi

I'm trying here as I don't feel Prostate cancer UK give enough specific advice on what I'm seeking.

I was thought to be in general good health at the time of being Diagnosed in 2022 with prostate cancer gleeson 6 (classed then as low grade). when aged 58 yrs (at that time amazingly having taken part in 5 marathons between 2009-2019).

However, despite staying on active surveillance and the PSA not varying too greatly, nov25 there was a spike and though since stabilised again at around 5, MRI in July 26 shows a slightly higher grade gleeson 7 as the cells have spread a bit and now focal therapy isn't sadly considered an option.

However, I have the choice of prostatectomy-nerve sparring (if all goes well) or radiation. I'm preferring the first option as I don't like the risk of the radiation straying and affecting other close by organs.

So, last appointment 4th Nov 26 when my consultant urologist has said I need to increase protein in my diet and do core strengthening pelvic floor exercises over the next few months to try and reduce the chances of urinary issues post op, especially as my MUL is only 9mm and thus I have a higher chance if incontinence post surgery.

If anyone had a similar pre op plan for a prostatectomy and they carried out their proposed high protein/low carb diet and essential core strengthening/ pelvic to a good standard, with good outcomes post surgery id be very grateful to hear your advice.

Many thanks, John
