Men who are deemed to be "heavy tea drinkers" are at a greater risk of developing prostate cancer, new research has suggested.
Scientists at Glasgow University discovered, in a comprehensive study involving 6,000 men over a 37-year period, that those who consumed more than seven cups of tea a day had a 50 per cent higher chance of developing the cancer than non-tea drinkers or those who drank around four cups a day.
Commenting on the study, lead author Dr Kashif Shafique, from the Institute of Wellbeing at the University of Glasgow, said that most previous research has indicated no relationship between tea and prostate cancer.
"We don’t know whether tea itself is a risk factor or if tea drinkers are generally healthier and live to an older age when prostate cancer is more common anyway," he added.
"We found that heavy tea drinkers were more likely not to be overweight, be non alcohol-drinkers and have healthy cholesterol levels. However, we did adjust for these differences in our analysis and still found that men who drank the most tea were at greater risk of prostate cancer."
Other interesting findings to come out of the study included heavy tea drinkers having healthy levels of cholesterol, be more inclined not to drink alcohol and not be overweight.
