The IARC examined studies that mostly looked at mate, a type of tea that is traditionally drunk at very hot temperatures, mainly in South America, Asia, and Africa.
50,045 individuals aged 40 to 75 years were followed by scientists for a median of 10 years, and during follow-up, 317 new cases of esophageal cancer were identified. But according to a new study, there's some evidence that drinking a really hot mug of it could heighten your risk of esophageal cancer.
The good news, according to Georgina Hill of Cancer Research UK, is that 60 C is "a lot hotter than most cups of tea".
Researchers found those who drink their tea less than two minutes after it is ready have a 51 per cent higher risk of gullet cancer than those who leave it for six minutes or more.

"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".
"In fact, it is probably anything hot: Microwaved jam has been known to cause esophageal injury", he was quoted as saying by the Science Media Centre. "It is possible that the trauma leads to cell changes and hence to cancer".
He added that the absolute risk is not quoted in the paper, which he calculated at about 63 cases per 100,000 people.
Beware, it could raise the risk of esophageal cancer, finds a study, reports CNN.
The research was conducted between 2004 and 2017 in the northeastern Iran province of Golestan, where drinking very hot black and green tea is common, and where high levels of ESCC have been noted in the past.
