Study by Parekh Shows that Prostate Cancer in Obese Men Likely to Go Undetected

Men who are obese are less likely to be referred for a prostate biopsy, finds a recent study by Niyati Parekh, an assistant professor in Steinhardt’s Department of Nutrition, Food Studies and Public Health. With faculty from the University of Medicine and Dentistry of New Jersey, Parekh found evidence to demonstrate that obese men also had lower biopsy rates compared to lean men.

A decision to perform a prostate biopsy is commonly based on the results of the PSA test,” says Parekh. “Lower PSA concentrations among obese men may make it less likely for them to be referred for prostate biopsy, thus leading to a lower detection rate of prostate cancer.”

Parekh’s study, published in the American Journal of Medicine and featured in Reuters Health September 2010, noted that lower Prostate-Specific Antigen (PSA) scores among obese men makes it more likely that prostate cancer can go undetected.

“The result of not being detected early for prostate cancer means that these men are detected with late stage prostate cancer that may have already has spread to the bones and other sites,” Parekh said.

Parekh is a nutritional epidemiologist who researches the relationship between diet and chronic disease.
