I'm only guessing here - I'm not a medic - but I assume 45+ is the 'sweet spot' ( can't think of a better term ! ) for prostate cancer. There's nothing stopping you booking a slot though - they don't enforce an age limit.
Opinion seems to differ but for the sake of a blood test that can narrow your chances of getting prostate cancer I'm willing to give a small bit of blood. Remember the NHS poo poos herbal treatment. And nobody likes to be poo poo'ed !!!!
Strangely, not generally. As a rule the NHS doesn't believe these blood tests prove anything when there are plenty of medical trials that suggest they do. And to be clear, these tests highlight if you should take further tests - i.e. you're at risk - not that you HAVE prostate cancer.
Some of you may remember the thread I started about my friend Lisa who within 8 weeks of being diagnosed with caner died. In part because she didn't get any smear tests done. She died at the age of 46 !!!!
I also mentioned in the thread, rather too briefly, about men needing to get cancer...
