Matt,
Right now here in the States, there appears to be a move away from regular testing for PSA (Prostate-Specific Antigen), a test which can serve as an early warning of possible cancer, but also seems to be plagued with a high rate of false-negative results and PSA can become elevated for other reasons, such as an infection. When I was battling four tick-borne diseases, my PSA rose dramatically, but we knew the cause and confirmed it with a biopsy.
The naysayers indicate this leads to expensive and unwarranted testing and much angst and some unnecessary surgery which can have suboptimal results. This group says prostate cancers are generally slow-growing and a person is more likely to die with it than from it.
PSA proponents say the best defense against prostate cancer is regular testing and then further investigation if there is a spike in PSA numbers. This group says by the time one has symptoms, it can be too late; testing means early detection that can save lives.
Even among urological practices here in my town, there is disagreement about which approach is best.
Unfortunately, I have lost four good friends to fast-growing prostate cancer; by the time it was found, it had metastacized (spread) to other organs and nothing could be done. A series of elevated PSAs alerted doctors to my own father's prostate cancer, which was also of the speedy kind, and he went for prostate removal and is still here, close on 20 years later. In his particular case, if left untreated, it is unlikely he would have survived.
I decided some years ago it would be a Good Idea to incorporate a PSA into my annual physical and use the results as a baseline to alert me in case of a change. Fortunately, my physician is of like mind. I'm 54. I've been happy with this approach, but it is something you have to decide for yourself. For some (perhaps even a majority), the odds look pretty good and ignorance is bliss and if there is a problem, it progresses slowly enough to not matter. For others, the idea of an early warning has great appeal, with options to be explored based on further investigation (i.e. a biopsy).
All the discussion so far has been a direct outgrowth of the OP's question about saddles and prostate health, but if things stray too far, I can always split the topic.
Best,
Dan.
