Drink coffee or hot tea may cause esophageal cancer – too hot to drink, coffee, tea or mate, is a habit that may cause esophageal cancer, warns the Organisation’s cancer agency World Health, which however raised suspicions about coffee and mate consumed at temperatures “normal”.
Consumption of hot drinks “at 65 degrees Celsius or more” is “probably carcinogenic” in humans, announced Wednesday the International Agency for Research on Cancer (IARC), in Lyon (France), whose works refer for cancers.
“These results suggest that hot drink consumption is a probable cause of cancer of the esophagus and that the temperature rather than the drinks themselves, which seems to be involved,” said Christopher Wild, Director IARC after a reassessment of the risk of carcinogenicity coffee, yerba mate and hot drinks consumed.

“Smoking and alcohol consumption are major causes of esophageal cancer, especially in many high-income countries,” said Dr. Wild.
However, the majority of esophageal cancers occur in parts of Asia, South America and East Africa, where they often drink very hot beverages.

China, Iran, Turkey and countries of South America, where tea or mate are traditionally very hot bus (about 70 ° C), the risk of esophageal cancer increases with temperature in which the beverage is consumed, according to studies.
“The normal temperature for coffee and tea in European countries and North America are well below. Coffee and tea are often buses below 60 degrees, “said Dr. Dana Loomis, an epidemiologist IARC
Esophageal cancer is the eighth most common cause of cancer in the world and a leading cause of cancer deaths, with about 400,000 deaths in 2012 (5% of all cancer deaths).
However, we do not know the proportion of cases of esophageal cancer can be linked to the consumption of very hot beverages, noted WHO’s cancer agency.
Revaluation
The approach aims to establish a risk of causing cancer, but not the level of risk, warns WHO agency.
This re-evaluation work, the summary appears in the journal Lancet Oncology, was conducted by a group of international experts “without conflicts of interest,” says Kurt Straif IARC.
The decision to classify the hot drinks from the “probably carcinogenic” is based on “limited data” otherwise they would row a notch above with proven carcinogens.
Coffee, one of the most consumed beverages in the world, is no longer considered “possibly carcinogenic” after the revaluation of experts on the basis of “more than 1,000 studies in humans and animal”.
In 1991, coffee was declared as “possibly carcinogenic” by IARC. He was suspected at the time to be involved in cancers of the bladder, on the basis of limited data, which mainly did not take sufficient account of smoking, a major risk for this cancer, or occupational exposure to products toxic.
Since then, a series of studies conducted in Europe, the USA and Japan, have not provided evidence of an association between prostate cancer and coffee.
Moreover, many epidemiological studies have shown that coffee consumption has no carcinogenic effect for cancers of the pancreas, breast and prostate cancer, and reduced risk was even observed for cancers of the liver and the endometrium (lining of the uterus), notes the IARC. Furthermore, data on the more than 20 other cancers, is not conclusive.
As for the mate (tea leaves), popular in Latin America but also in the Middle East, provided they drank cold or too hot, it is not considered a carcinogen.
