Hello Janey and welcome.
As Chris says, get the Toolkit through publications or through the onsite nurses. Very helpful and full of information.
You say your dad has elected to go for Radical Prostatectomy and there are many on here who have had the same. Do you know whether it is open surgery, or robotic?
It's just that we have members who have had both (not the same member obviously!) and they will have relevant info for your dad's choice.
We do all understand exactly how you are all feeling because we have all trodden the same path,even if we veered off into different treatments. That initial diagnosis is frightening isn't it.
Do you know any of your dad's scores - his PSA or his Gleason scope for instance?
In the meantime, don't panic. Ask away any questions you/he might have. Somebody is bound to know the answer.
Best Wishes
Sandra
