HW views on exercise...

I guess it's kinda like pomegranate juice - can't hurt so what have you got to lose?

A current study indicates a clear benefit for PCa specific survival with exercise and rigorous exercise having the greatest benefit.

However, the National Cancer Institute says mostly no...except one recent study where exercise helped folks 65 and up.

What is the relationship between physical activity and risk of prostate cancer?
Research findings are less consistent about the effect of physical activity on prostate cancer, with at least 36 studies in North America, Europe, and Asia. Overall, the epidemiologic research does not indicate that there is an inverse relationship between physical activity and prostate cancer (4, 7). Although it is possible that men who are physically active experience a reduction in risk of prostate cancer, the potential biological mechanisms that may explain this association are unknown, but may be related to changes in hormones, energy balance, insulin-like growth factors, immunity, and antioxidant defense mechanisms (7). One recent study suggested that regular vigorous activity could slow the progression of prostate cancer in men age 65 or older (9). sad mad

that's what i expect a sedentary person -- who's very unwilling to change even with his health on the line -- to say.  exercising didn't prevent me from getting prostate cancer but it's helping keep my mind and body strong as i gird up for the fight of my life.

Contraire F8,

I've started running a lot and love it - and will do so regardless of any substantiated PCa benefit. I'm just fishing for data beyond the anecdotal i.e., Michael Milken etc. Milken's story is inspirational and he had little clinical evidence to guide him. I've changed my diet considerably but still researching the ins and out - I've eliminated red meat, dairy and still working on shifting a higher percentage of my protein to non-animal protein. And yes, I'm a pomegranate lush (daily). Lots of veggies.

I read too many studies.....who was it that said there are three kinds of lies; lies, dam lies and statistics. I have serious doubts about some of these studies.

The best to you F8 - I'm a T3a and just entered the fight in April.

K2,
There might not be any evidence that it affects PCa directly but there is plenty of data that show exercise helps your other organs: heart, lungs, etc. I am much more than just my prostate. (Fortunately, since I don't have one.)
For the first 18 months post RP I was incontinent. I would squirt when I moved, bent over, walked, ran, or read a funny HW post. Very subtly that became an excuse for me to slack off. After I got the sling and was able to do things again, I noticed how quickly I became winded. It took me ~4 months but that is fixed now.
Regarding the "lies, lies, and statistics". They say the only way you truly know you are cured of PCa is when you die of something else. Imagine a person who starts eating 5 pounds of red met daily and dies of a heat attack in a month. A good statistician could correlate the two and use that as proof of a PCa cure. ;-)

Actual one of the studies I originally cited finds a clear PCa benefit to exercise.
Other than the various types of surgery/radiation/drugs the only other area left is the holistic mind/body/spirit (to include exercise) not an area the medical establishment is particularly fond of so, they don't seem to advocate much for it. Again, someone like Michael Milken would probably say it definitely makes a difference.

Contraire F8,

K2 -- that wasn't aimed at you specifically.  i don't know your history.  i'm just saying where i'd expect to hear that type of comment.  i've exercised vigorously most of my adult life.  i've always figured it was cheaper than a shrink  cool  .  i often wondered about milken or even someone like zufus.  you know, how'd they do it?  the fact is they could be exceptions but nevertheless i'm going to listen when they talk even if it means breaking out the foil cap cool .
