First of all age has nothing to do with how well we handle life's stresses. My dad had a stroke when I was just about your age and I can tell you I reacted much the way you are now. I don't have a whole lot of knowledge about your dad's particular type of cancer, but I did work with a woman whose husband had prostate cancer. He had some sort of surgery where they implanted some "seeds" that I believe delivered radiation to the cancer. She is no longer at my office, but the last I heard he was doing just fine. I am sure the doctors will have many options for your dad. So many strides are being made in cancer treatment these days. Try and keep your chin up for your dad's sake as well as your own. Please do let us know how he is doing. ((((hugs))))
