Researchers found that people who preferred tea above 140 degrees Fahrenheit and drank more than 24 ounces of tea a day (about two large cups) had a 90 percent higher risk of esophageal cancer than those who drank less tea and at cooler temperatures, CNN reported.
The study, which included more than 50,000 adults in Iran, was published in the International Journal of Cancer.
"Many people enjoy drinking tea, coffee, or other hot beverages. However, according to our report, drinking very hot tea can increase the risk of esophageal cancer, and it is therefore advisable to wait until hot beverages cool down before drinking," lead author Farhad Islami, from the American Cancer Society, told CNN.
A previous study linked hot tea with esophageal cancer, but this new one is the first to pinpoint a specific temperature, according to the researchers.
Esophageal cancer is the eighth most common cancer in the world and kills about 400,000 people a year, according to the International Agency for Research on Cancer.
In 2019, the United States will have 13,750 new cases of esophageal cancer diagnosed in men and 3,900 new cases in women, the American Cancer Society estimates.
