I know this topic has been posted in the past, but that would have been at a time where it was not in my line of sight, so I decided to throw this out here again.
The only people I have told about my PCa Dx are my wife, best friend, son (32 years old) and brother (49 years old). I am the oldest of the siblings at 55, our sister is 50 and I told her as well when I met with my brother.
My reasoning for telling my son and brother are of course obvious. My son will be talking to his primary physician about his Dad having PCa so they can plan accordingly (anyone have an opinion as to when he should get his first PSA done?) My brother just got his first PSA reading yesterday after I told him about my PCa and how he also needs to be aware. Fortunately his came out at 0.79, YEAH! He now has the all important PSA baseline with which to work. Hopefully he and my son will be spared the beast, but they are now both aware that it has reared its ugly head in our family. My Dad's last check up, at age 79, was PSA 0.5 so that's a good thing as well. Mom and Dad don't know about my PCa, and never will - they don't need that hanging on them and besides with me it's so far, so good.
So then I have also made the decision to tell no one else, and the few that I have told are respecting my wishes of keeping it to themselves. My reasoning - why put this burden on others to begin with, and if I am indeed able to beat the beast or at least keep it at bay, then why say anything. Part of my own psyche is that I also don't want to be treated "differently" nor do I want some kind of darn "pity party" about it.
Just sharing my own thoughts and approach and wondering how others feel and have chosen to deal with this.
