Prostate cancer warning

In an attempt to identify risk factors that contribute to prostate cancer, an international team of researchers - led by Oxford University - compared the data from blood samples of 3,700 men with prostate cancer and 5,200 men without the disease.

The study, Annals of Internal Medicine, found that men with high levels of a protein called Insulin-like Growth Factor-1 (IGF-1) were more likely to go on to develop prostate cancer than those with lower levels of the protein.

Scientists hope that the research might enable them to develop specific diet and lifestyle advice for men at high risk of prostate cancer.

Lead author Dr Andrew Roddam, a Cancer Research UK epidemiologist at the University of Oxford, said: "Now we know this factor is associated with the disease, we can start to examine how diet and lifestyle factors can affect its levels and whether changes could reduce a man's risk."
