Chris Hoy's situation sounds, as NS says, fairly close to my own story.
That he is this this position at an age 20 years younger than I was when I was diagnosed is especially sad - and I recall how bleak it all sounded at the time, when I was told that there was a 50% chance I wouldn't survive for 5 years. In my case that was just over 4 years ago now and I'm still here, albeit a bit worse for wear, so hopefully he will get that 4 years too, and maybe a bit more.
As NS says men of a certain vintage, and especially if there is a family history of prostate cancer, should request to be tested: I had no early symptoms and by the time I did have symptoms it was already too late and I was seriously ill - and the lovely people at the Beatson West of Scotland Cancer Centre told me that had I been tested a year or so before I became ill my cancer would have been treatable (as in being potentially 'curable').
Don't take no for an answer: the stakes are too high. My disease classification on diagnosis was (and still is) T4N1M1b so google that if you want to know what you, or someone you know, might avoid by getting tested.
