Yes, as Dave says, order the free comprehensive information pack ‘Toolkit’ from this charity.

A PSA of 14 at your age, is not ‘very high’, 50, 60 or hundreds is. If as you say, there is no cancer detected, why are they offering you cancer treatment?
Have you had a biopsy? What was the staging or Gleason score, G=X+Y=Z?
If you opt for surgery, look for a high-volume surgeon who does at least 100 prostatectomies a year. Practice makes perfect. This should improve your chances of post-operative continence.
You should seek opinions from both surgical and oncological branches of medicine before you make mind up on any treatment plan. You are entitled to second opinion(s) from specialists, even on the NHS.
Best of luck.
Cheers, John.
