Tea drinkers who consumed less of the beverage at cooler temperatures were significantly less at risk.
According to a study, drinking extremely hot tea can increase the risk of esophageal cancer. An article published in the journal Burns in 2016 found that a cup of tea with 10ml of milk cooled to less than 65 C in under five minutes.
They said that the drink was not associated with the cancer at all rather the temperature is the real victim in doing so to all types of tea. But this study, say the authors, is the first to pinpoint a specific temperature of tea.
The American Cancer Society reports there are about 17,650 new esophageal cancer cases diagnosed each year in the country, largely in men. However, they also recommend further studies on the reason behind the connection.
"If you go to the Middle East or to Russian Federation, they drink it out of a samovar that's constantly under heat", Peter Goggi, president of the Tea Association of the U.S., told CNN in 2018.
