Dear dogs_with_bees,
What are the most common risk factors for prostate cancer?

Does bicycle riding increase my risk for prostate cancer?
Bicycle riding does not cause prostate cancer. To clarify a common point of confusion, Lance Armstrong had testicular cancer (which also is not related to bicycle riding or prostate cancer).

Your risk of getting prostate cancer increases as you get older, have African ancestry, or have a family history of prostate cancer in a close relative.

How does my family history for prostate cancer affect my risk for developing prostate cancer?
If a first degree relative (I.e. father, brother) has prostate cancer, particularly at an age less than 60 years old, there is an increased risk for prostate cancer in the individual. These individuals should have a PSA test and digital rectal exam on a yearly basis starting at age 40.

How does the amount of fat in my diet affect my risk for prostate cancer?
There is a belief that a high fat diet typical of Western societies is associated with a higher rate of prostate cancer. The association of prostate cancer and fat consumption is based on observations and some animal experiments, though a true cause and effect relationship has not been established. Much work needs to be done in this area. What is important in any diet is to have moderation in what one eats.

Does taking calcium carbonate increase the risk for prostate cancer?
Administration of calcium carbonate does not present an increased risk for prostate cancer. There were some reports about milk intake and prostate cancer, but this may relate more to the fat content of milk rather than calcium.

Do high levels of testosterone increase my risk for prostate cancer?
There is no evidence to suggest that high blood levels of testosterone can cause prostate cancer.

How does sexual activity affect my risk for prostate cancer?
There is some evidence that individuals who have had multiple sexual partners in their teens may be at a higher risk of prostate cancer as they age, but this increase is small. Generally, though, there does not appear to be any relationship between sexual activity and prostate health, or the growth or spread of prostate cancer.
