Hi ruthedwards
I have followed the expert in this video for some years now. He is quite dogmatic and appears to be against prostatectomy (refers to urologists who perform prostatectomies as 'prostate snatchers'!) which is not very helpful.
Newly diagnosed men ideally want unequivocal answer for their choice of treatment which is generally not possible because prostate cancer is a very complex disease. Unfortunately consultant-bias does not help when urologists and oncologists try to influence your choice towards their speciality.
Most men, if they can, would prefer to have their prostate removed because it appears to promise a permanent cure. However the success of a prostatectomy depends on the certainty of whether the cancer is well contained within the gland, with clear and sufficient negative margin. MRI can help but until the prostate is examined after the surgery you can't be certain. Of course even an MRI can't detect a single cancer cell which may have escaped and lie dormant for many years or may never develop into a serious tumour.
You don't expect to undergo any other treatment if you have a prostatectomy unless you are unlucky or the surgery is not performed competently.
You need good advice. Good luck.
