Report links advanced prostate cancer to obesity

According to a report from the World Cancer Research fund, obesity greatly increases the chances of developing aggressive prostate cancer. 1

The report was an update from an original analysis in 2007, and reviewed 104 studies assessing more than nine million men. It compared their diets, physical activity, nutrition, weight and their overall risk of prostate cancer. Of that group, 191,000 had prostate cancer.

The report revealed some limited evidence linking diets high in dairy or calcium with increased prostate cancer risk, and also signs that low levels of vitamin E in the blood could also increase cancer risk. In addition to these findings, the review found strong evidence that being tall could be an increased factor, which is linked to developmental factors in childhood and adolescence.

The report ends by recommending men retain a healthy bodyweight, exercise regularly and eat a healthy diet to reduce their risk of cancer.

Prostate cancer is the most common form of cancer in men, with over 40,000 being diagnosed in the UK every year and 250,000 men currently living with it. It is estimated that one in eight men will develop prostate cancer in their lifetime, with most being diagnosed with it in their 70s.
