Drinking hot tea linked with elevated risk of esophageal cancer

The study said more research was needed on why exactly drinking very hot tea is associated with the higher risk of esophageal cancer.

What's more, those who drink their hot drinks at 75°C are as much as 2.4 times more likely to develop the cancer, the research found.

"As smoking is a recognised risk factor for oesophageal cancer both mechanisms could play a part, interacting to increase risk in the case of smokers who "like it hot".

Hot beverage lovers may now have to think twice before sipping on a cuppa full of a burning coffee or tea, following a new scientific study on the impact of the habit.

That's according to research conducted by scientists from Tehran University of Medical Sciences in Iran, who have discovered a link between drinking boiling hot water and the development of cancer of the oesophagus.

The study looked at more than 50,000 people in Golestan, a province in northeastern Iran.


A new study uncovers a correlation between hot tea and cancer, but you don't have to worry if you drink your tea at a reasonable temperature.

The study identified 317 new cases of ESCC among its 50,045 participants, who were tracked on average for just over 10 years.

The International Agency for Research on Cancer (IARC) has already classified drinking very hot beverages (65 C or higher) as a "probably carcinogenic" and the researchers say this only adds more proof. Compared with drinking less than 700 ml of tea per day at less than 60°C, drinking 700 ml per day or more at a higher temperature (60°C or higher) was associated with a 90 percent higher risk of esophageal cancer.

The American Cancer Society estimates that 13,750 new cases of esophageal cancer will be diagnosed in men and 3,900 new cases in women in the United States in 2019. Evans was not involved in the study.

However, adding cold or warm milk will reduce the temperature, making them safer to drink. "It's very, very hot".

Professor Mel Greaves, from The Institute of Cancer Research, said: "It isn't clear why or how hot liquid has this apparent effect".
