Studies Show Obese Men Face Increased Prostate Cancer Risks

Obese men may be more vulnerable to prostate cancer, according to two recent studies released this week by Duke University.

In the first study, researchers found that obese men face twice the risk of being diagnosed with aggressive prostate cancer because their screening test results are frequently less accurate.

Prostate cancer screening tests check the levels of prostate-specific antigen (PSA) in the blood. Elevated levels of PSA indicate a greater risk of prostate cancer.

Obese men frequently return lower PSA measurements, likely because they have more blood, which would dilute their PSA levels.  By the time their PSA readings reach what is considered to be an elevated level in normal-weight men, the cancer is likely to be in an advanced stage.

The study included data from nearly 3,400 men.

A second study from Duke found that weight can influence the success of surgery for prostate cancer.

Researchers determined that there is a greater chance that surgeons will not be able to remove all of the cancer due the difficulty of operating on obese men and the aggressiveness of the cancer.

Both studies were published in the online issue of BJU International.
