Drinking more coffee could reduce the risk of developing the most common form of primary liver cancer, according to a study led by Southampton.
Researchers from Southampton and the University of Edinburgh found that the more coffee consumed the greater the protection against hepatocellular cancer (HCC). Drinking one more cup of caffeinated coffee a day than your usual amount, but not exceeding five cups, was associated with a 20 per cent reduction in the risk of developing HCC, two cups more with a 35 per cent reduction, and up to five cups with a halving of the risk. HCC is the second leading cause of cancer death globally because of its poor prognosis and high frequency, especially in China and Southeast Asia. It mostly develops in people who are already suffering from chronic liver disease. It is estimated that, by 2030, the number of new cases annually will have risen by about 50 per cent to more than 1.2 million. The compound molecules found in coffee possess antioxidant, anti-inflammatory, anticarcinogenic and other beneficial properties which scientists believe may explain the lower rates of chronic liver disease and liver cancer experienced by coffee-drinkers. The research, published in the journal BMJ Open, examined the data from 26 observational studies, involving more than 2.25 million participants, to calculate the relative risks of developing HCC for drinking between one and five cups of caffeinated coffee a day. Lead author Dr Oliver Kennedy, of the University of Southampton, said:Coffee is widely believed to possess a range of health benefits, and these latest findings suggest it could have a significant effect on liver cancer risk.
