Men who drink a lot of tea are more likely to develop prostate cancer, say researchers at the University of Glasgow.
The study tracked the health of more than 6,000 men over 37 years and found those who drank more than seven cups of tea a day were 50% more likely to get prostate cancer than non-tea drinkers or those who drank fewer than four cups a day.
But the researchers admit that the tea might not be causing cancer but, rather, adding years onto men's lives.
"Most previous research has shown either no relationship with prostate cancer for black tea or some preventive effect of green tea. 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," said lead author Kashif Shafique.
The study was published in the journal Nutrition and Cancer.
