Drinking hot tea almost doubles the risk of cancer, says new study | New

(CNN) – Many people start their day with a cup of tea. But according to a new study, those who drink very hot could increase their risk of cancer of the esophagus.

The researchers found that tea drinkers who liked their drink at a temperature above 60 ° C (140 ° F) and consumed more than 700 ml of tea a day – about two large compared to those who drank less tea and at cooler temperatures.

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

"Many people like to drink tea, coffee or other hot drinks." However, according to our report, drinking very hot tea can increase the risk of esophageal cancer, and so it is advisable to Wait until the hot drinks cool down before drinking, "said Dr. Farhad Islami, of the American Cancer Society and senior author of the study.

Previous research has shown a connection between hot tea consumption and esophageal cancer. This study, published Wednesday in the International Journal of Cancer, was the first to identify a specific temperature, according to the authors.

Esophageal cancer is the eighth most common cancer in the world and is often fatal. It kills an estimated 400,000 people each year, according to the International Agency for Research on Cancer. It is usually caused by repeated lesions of the esophagus due to smoke, alcohol, acid reflux and, perhaps, hot liquids.

The esophagus is a long tube through which swallowed food and liquids travel to reach the stomach.

The American Cancer Society estimates that 13,750 new cases of esophageal cancer will be diagnosed in men and 3,900 new cases among women in the United States in 2019.

The research team followed 50,045 people aged 40 to 75 for an average of 10 years. Between 2004 and 2017, researchers detected 317 new cases of esophageal cancer.

The study found that more research is needed on why drinking hot tea is badociated with a higher risk of esophageal cancer.

Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine, said the problem was more heat than the type of drink.

"In fact, it's probably something hot.Microwave jam is known to cause lesions of the esophagus.It is possible that the trauma results in cellular changes and therefore cancer", he told the Science Media Center. Evans was not involved in the study.

In the United States and Europe, tea is rarely consumed at temperatures above 65 degrees Celsius (149 degrees Fahrenheit). However, in countries like Russia, Iran, Turkey and South America, it is common to drink tea as hot or warmer.

"If you go to the Middle East or Russia, they drink it in a constantly heated samovar," said Peter Goggi, president of the Tea Association of the United States last year. "It's very hot."

Dr. James Doidge, senior research badociate at University College London, said that hot drinks were an established risk factor for esophageal cancer.

"It does not take a scientist to understand that repeated irritation of the surface of the body increases the risk of cancer.Sburns cause us skin cancer, smoking causes us lung cancer and many Foods and beverages contribute to the risk of gastrointestinal cancers, "said Doidge, who did not participate in the research, told the Science Media Center.
