Piping hot tea raises cancer risk

The study showed that risk of esophageal cancer more than doubled among those who regularly drank tea at 75 degrees Celsius However, waiting for at least four minutes before drinking a cup of freshly boiled tea can reduce the risk of the cancer arising from the oesophagus—the food pipe that runs between the throat and the stomach. 

“Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking hot tea can increase the risk of esophageal cancer, and it is therefore advisable to wait until hot beverages cool down before drinking,” said lead author Farhad Islami of the American Cancer Society.

The study, published in the International Journal of Cancer, involved 50,045 individuals aged 40 to 75 years. 

Drinking 700 ml per day of tea or more at a higher temperature (60 degrees Celsius or higher) was associated with a 90 per cent higher risk of esophageal cancer, the researchers said. The results could also be extended to coffee, hot chocolate or other hot beverages. Esophageal cancer is the sixth most common cancer in India.—IANS
