The study also showed anincreased risk in men with smaller prostates. The study wasconducted at a Veterans Affairs hospital in California from 1998to 2002. It included 787 men who had biopsies for suspectedprostate cancer and showed that obese men were more likelyto have positive results. Obese men also have more aggressivetumors, the study showed.
