We don't have the details of all your stats (pathology report details), but based upon what you mentioned you probably don't need to rush into anything. PCa usually takes years and decades to get to the point where it may be found or detectable, autopsies done on younger folk(30's-40's) found them with PCa (studies) say, and it would be usually indolent or low risk territory on those findings, PCa could change over time and become more viralent,but not always. Patients in your risk area have time to decide.
Are you aware of the definition of 'indolent PCa' ? Maybe surveilance is a real option?
Maybe there are other options and choices?
Did you have your pathology reviewed by some of the few experts?
Did you see an onco-doc for possible opinion?
Are you prepared to accept all the risks that come with surgery? What about postphoning it for perhaps years, and do other drug protocols or options, whereby you can remain continent and not have e.d.(long term) and maybe even keep manhood intact?
My brother got diagnosed with similar looking stats about 5-6 yrs. ago now, he has done nothing thus far, no problems, no psa rises, has healthy diet and lifestyle. He will have to decide when and if on his own case.
Good luck to you in whatever way you go, alot roads lead to Rome.
