With surgery, they frequently leave Cancer tissue, someone else was asking for about it in the last couple of days, when they had positive margins after surgery.

Many of us have had surgery and then days, weeks, months, years later needed salvage radiation to clean up the prostate area. For me, it was 3 1/2 years after surgery.

The biggest complaint about radiation is that they damage organs near the prostate, Using something Like MRI guided SBRT can avoid that.

With your case you can also consider HIFU , Cryoabalation , NanoKnife , TULSA PRO, HoLEP.
