Well, the symptoms can be a little subtle, depending on circumstance - I went through a patch of lots of night-time piddling (not in the bed, I hasten to add) - but not helped by often drinking tea before bed, which I've always done (tho' I've tried to reduce that of late). Likewise I often take a while to get piddling - but I've always been like that. I wound up with a PSA test as a result of hassling my GP after having possible oesteopenia flagged up during a national health screening research project.
A PSA of 6.7 meant a visit from Mr Marigold - turns out it's just a slightly enlarged prostate, but at least now I know. Second test was 3.7, yet to hear results of 3rd. So long at it's not increasing significantly/longterm I won't worry, but I'd certainly rather know than live in ignorance. Yeah, I realise most of us blokes will die with prostate cancer, rather than from it...
>It can be raised in cases of benign enlargement of the prostate, urine infections, after sex, and yes after a finger up the bum.
And cycling !
