In a new study, researchers found drinking hot tea is linked to increased risk of esophageal cancer.
The finding suggests that drinking very hot tea is not safe and that people should wait until hot beverages cool down before drinking.
The research was reported by the American Cancer Society.
Many people enjoy drinking tea, coffee, or other hot beverages.
But previous studies had shown that hot tea drinking is linked to risk of esophageal cancer.
It is cancer arising from the esophagus, which is the food pipe that runs between the throat and the stomach.
However, no study has examined this link with accurately measured tea drinking temperature.
In the current study, the team examined 50,045 adults aged 40 to 75 years for about 10 years.
The team found that during the time, 317 people had esophageal cancer.
Compared with people who drank less than 700 ml of tea every day at less than 60°C, people who drank 700 ml per day or more at a higher temperature had a 90% higher risk of esophageal cancer.
The finding is in line with recent findings. For example, one study from USC and collaborators found that drinking beverages hotter than (65 degrees Celsius) may increase the risk of tumors in the esophagus.
Researchers in that study reviewed more than 1,000 studies on over 20 different types of cancer.
They concluded that drinking any beverage hotter than 65 degrees Celsius is probably carcinogenetic to humans.
This means drinking hot beverage can be as harmful as DDT, eating frying food at high temperatures, eating red meat and the HPV.
The researchers suggest that when people drink hot coffee, tea, and the caffeine-infused beverage, they should wait until the beverage cools down.
The lead author of the study is Dr. Farhad Islami from the American Cancer Society.
The study is published in International Journal of Cancer.
