Very hot drinks may damage the food pipe and increase cancer risk

Regularly drinking beverages like tea and coffee at very hot temperatures increases the risk of cancer of the food pipe or gullet, known as oesophageal cancer, UK research suggests.

Researchers say the findings , external , from a study of nearly a million people, make this the largest to date to establish the link.

In the study, people who had their drinks "very hot" had around a three times higher risk of the cancer than "warm" tea or coffee drinkers - although experts stress the overall chances of developing this cancer are low.

Steaming hot liquid can damage the cell lining of the food pipe on the way down to the stomach.

The work by Oxford University, which is published in the International Journal of Cancer, defines any drink at 65 degrees Celsuis or above as "very hot" and posing a potential risk.

Consuming six or more hot drinks per day also raises the risk, according to data from 977,282 middle-aged men and women.

Although adding milk can cool drinks down slightly, a milky tea or coffee may still be far too hot, researchers say.

Tea made immediately after a kettle is fully boiled is touching boiling point, which is 100 degrees C (212 degrees F). Once poured into a cup, that lowers to around 90 or 95 degrees C.
