London: There is a reason to get scared if you have that extra flab on your belly! A study has revealed that being obese could limit a man's chance of surviving prostate cancer.

Researchers at Duke University Medical Centre have carried out the study and found that obese men are three times more likely to see the cancer spread beyond the prostate than
those of a healthy weight.

One of the researchers, Prof Stephen Freedland, said: "The study supports a growing body of literature showing that obese men with prostate cancer do worse. Our next step is to
figure out why."

The researchers have based their findings on an analysis of 287 men whose diseased prostates had been removed, and who had then seen cancer return. All were given chemicals called androgen deprivation therapy (ADT) to limit levels of natural testosterone, which can trigger prostate cancer.

Those who were obese were three times more likely to have seen the returning cancer spread beyond the prostate after five years as those of a healthy weight,a process known as progression, a news daily reported.
