Obese Men May Need Additional Prostate Cancer Tests

The gold standard for prostate cancer screening, the PSA test, may not be entirely accurate in obese men.

Researchers at Duke University found that PSA levels for obese men were low and that could be because larger blood volumes dilute the readings. After looking at records from 3,400 men, they found that obese patients whose cancer was found with PSA testing had twice the risk of recurrence than men of normal weight.

However, obese men who were diagnosed by a digital rectal exam had similar outcomes to men with an average weight. The study also found obese men were more likely to have cancer left behind after surgery.
