Welcome. Like the rest of the guys we all wish you weren't becoming one of us.
PC is very serious but catching it as soon as you did as well as researching all the options is a good step.
Hopefully you and if you have a better half have reviewed all the information you can find and discussed both the options and potential results.
The knife, which I had before the robotics became common, so far as solved the PC problem. It also gives you options which you may not have if you used Radiation, Chemo or etc.
Good Luck and our Prayers and thoughts are with you and yours.
Tom of West Ohio.
