Chance of survival increases in obese patients with advanced prostate cancer Chance of survival increases in obese patients with advanced prostate cancer Last Updated: Sun, Jul 11th, 2021, 10:20:08hrs Amsterdam [Netherlands], July 11 (ANI): A new research has found that obese patients with a form of advanced prostate cancer survive longer than overweight and normal-weight patients. The study, presented today at the European Association of Urology Congress, EAU21, followed more than 1500 patients over three years. Patients classed as obese - with a BMI over 30 - had a ten percent higher survival rate than thinner patients over 36 months. Although obesity is usually associated with an increased risk of death from many cancers and some other chronic diseases, there is some evidence in a few cancers of a survival advantage for patients with a high body mass index. This phenomenon is known as the 'obesity paradox'.
