Men who drink six or more cups of coffee each day are 20 per cent less likely to be diagnosed with prostate cancer.
This is according to a new study carried out at the Karolinska Institute in Stockholm, Sweden.
It found that high consumption of coffee helps to fend off localised cancer. This is the slow growing type of tumour which takes years to develop.
The study found that coffee has no effect on more aggressive forms of cancer.
Almost 45,000 men aged between 45 and 79 took part in the 12-year study and scientists found that the best results were seen in men who were carrying a few extra pounds or grossly overweight.
"Increased adiponectin levels due to coffee consumption may be more beneficial to overweight and obese men," researchers said.
"Our results are potentially important from a public health point of view."
Each year, around 40,000 men in the UK are diagnosed with prostate cancer.
