Good morning, Countrygirl.
Take it easy. Here you will find great support, as I do.
I'm not an expert at this subject yet as my husband is just beginig this bad journey, but as some member on here say, "PCa isn't always curable but it's treatable."
Give more details about Dad's issue so they can help you: age, Gleason, stage, tests, etc etc.
Everyone must be sleeping right now, but I am sure they will give you some wise and relieving response later.
Best wishes,
Lola.
