A new study conducted in China and published in the Annals of Internal Medicine suggests drinking hot tea can increase the risk for esophageal cancer in people who smoke and drink alcohol. Smoking and drinking are known risk factors for cancer of the esophagus – the eighth most common type of cancer worldwide.
This study involved 456,155 people between the ages of 30 and 79 in China. People with cancer, as well as those who had already reduced their consumption of tea, alcohol, or tobacco products, were excluded from the study. The participants provided information about their lifestyle habits – smoking drinking, tea consumption, and others – including the usual temperature at which they drank their tea (warm, hot, or burning hot).
According to researchers, 1,731 cases of esophageal cancer were documented during the 9-year follow-up period. Burning-hot tea drinking combined with either alcohol consumption or smoking was associated with an increased risk for esophageal cancer than high-temperature tea drinking alone.
