Men who regularly drink coffee may be less likely to need advanced prostate cancer treatment than those who rarely consume the hot beverage, new research suggests.
A study presented at a meeting of the American Association for Cancer Research found that men who drank the most coffee were 60 per cent less likely to develop aggressive prostate cancer than those who never had it.
Coffee contains many active compounds such as antioxidants and minerals and it is thought to be one or more of these that affects prostate cancer risk, rather than caffeine.
The study involved nearly 50,000 men, 4,975 of whom developed prostate cancer over a 20-year period.
Dr Kathryn Wilson, from Harvard Medical School and the Harvard School of Public Health, commented: "Coffee has effects on insulin and glucose metabolism, as well as sex hormone levels - all of which play a role in prostate cancer.
"It would be very exciting if this association is confirmed in other studies."
The majority of cases of prostate cancer occur in men over the age of 70.
As well as age, risk factors for the disease include family history and being of African ancestry.
