I echo that everyone is different. Some want to know everything and others want to know as little as possible. I think one needs to respect both. Lucie's onc would not have volunteered any prognosis, but we asked because we wanted to react to it, get it behind us and move on. The prognosis (statistics) was, as Ry says, waaaaay off! It was nine months, and Lucie is now 28 months out and going strong.
Lucie does not participate in this forum because she does not want to be overwhelmed with the info, the bad news, etc. She lets me do that, which I don't mind, and I give her what info, support from here she needs. It works out well that way for us. Don
