Hot tea can increase the risk of a deadly cancer five-fold for people who also regularly drink alcohol, Chinese research suggests.

People who drink at least one alcoholic beverage and a "burning hot" cup of tea on a daily basis were five times more likely to develop esophageal cancer than people who drank tea at any temperature less than once a week, the study found.

The risks to smokers also increase with high-temperature tea drinking, said the study, which examined data on 456,155 Chinese adults ages 30 to 79. Drinking boiling hot tea every day was associated with roughly twice the risk of oesophageal cancer as consuming tea less than weekly for people who smoked.

Both smoking and drinking alcohol are already widely-known to be linked to oesophageal cancer, but the new study, which appeared in the Annals of Internal Medicine, proved that very hot tea can increase the risks.

Lv Jun, of Peking University Health Science Centre in China, who co-authored the study, told The Telegraph: “Boiling hot tea will harm the cells in the oesophagus. “If the person also drinks alcohol and smokes, then the harm caused will be more heightened.”

At the start of the study, none of the participants had cancer. Researchers followed half of the participants for at least nine years.
