Among prostatectomy patients, those with diets high in high saturated fat (HSF) are almost twice as likely to experience biochemical failure as those who consume a low saturated fat (LSF) diet, say US scientists.

Several studies have indicated that obesity is associated with an increased risk of biochemical failure after treatment with radical prostatectomy or external beam radiation for localized prostate cancer.

Patients at risk of prostate cancer and thos with prostate cancer should reduce their fat intake.
