Survival Rates

I’ve been on active surveillance for 2 years with localised prostate cancer gleeson score 3-4.

Recently I’ve come across articles on survival rates after 15 years for surgery, ebrt and active surveillance the surprising outcome was that there was over 90% survival rates no matter what course of action was chosen. Iam now 72 it seems very appeared to continue with active surveillance with a good chance I will live into my late 80’s. I’m interested in any feedback
