Fat men are at greater risk of developing advanced prostate cancers – including aggressive cancers that are fatal, says a new report.

It found ‘strong evidence’ of a link between being overweight or obese and advanced prostate cancer.

A report from a leading cancer prevention charity estimates that one in 10 advanced prostate cancer cases in the UK could be prevented, if men kept a healthy weight.

Prostate cancer is the commonest cancer in men. In the UK, more than 41,000 men are diagnosed each year and the condition leads to approximately 10,000 deaths a year.

The finding was made after an analysis of the global scientific research into lifestyle factors and prostate cancer in the World Cancer Research Fund’s Continuous Update Project (CUP).

The report, the most in-depth review to date, analysed 104 studies involving more than 9.8 million men and over 191,000 cases of prostate cancer.

It casts doubt on links previously made between prostate cancer risk and certain foods.

The evidence linking diets high in calcium to an increased risk of prostate cancer has been downgraded from ‘strong’ to ‘limited’.

Evidence that foods containing lycopene such as tomatoes cut the risk of prostate cancer, has been downgraded from ‘strong’ to no conclusion possible.

The evidence that a diet higher in dairy products increases risk, remains limited.

The report, the result of a partnership with Imperial College London, is the most in-depth review to date of research linking diet, physical activity, and weight to the risk of developing prostate cancer.

Kate Allen, Executive Director Science and Public Affairs at World Cancer Research Fund International, said ‘It is the first time we have been able to show any kind of link between advanced prostate cancer and weight.

‘The emergence of a link between body fatness and advanced prostate cancer could have important implications.

‘It may raise questions in relation to prostate cancer screening, in particular, whether excess weight ought to be included alongside factors like family history in discussions between GPs and men at risk of advanced prostate cancer.’

Dr Jonathan Rees, GP and Chair of the Primary Care Urology Society, said ‘With so much controversy over the merits of screening for prostate cancer, it is vital in primary care for us to understand which patients are most at risk of developing this disease.

‘The findings of this review point us towards recognising overweight or obesity as a risk factor to take into account when discussing screening with patients.’
