Study: Hot Drinks Increase Cancer Risk
To protect against cancer, milk should be added to hot drinks like tea and coffee. If the temperature of these drinks is too high, then the risk of developing esophageal tumors doubled.
Drinking too hot tea or coffee more than doubles the risk of developing cancer, as scientists at Tehran University of Medical Sciences have found, writes MedicForum. Iranian scientists have received another confirmation of the connection of hot drinks and a dangerous disease.
If people drink daily tea with a temperature of 60 C or higher, the risk of esophageal malignant neoplasms increases by 90%. In order to reduce it, you need to allow the drink to cool for a few minutes or add milk there.
For the first time, researchers were able to prove this connection during a large-scale observation that lasted for a long time. Too hot drinks irritate the mucous membranes of the mouth and throat, which is a kind of "fuel" for tumors, as scientists believe.
In the world, esophagus cancer is the eighth most common malignant neoplasm, as well as one of the main causes of death from tumors. Researchers believe that the data they obtained about tea is also true for other drinks, including coffee or hot chocolate.
In general, the study lasted for 13 years; slightly more than 50 000 people aged from 40 to 75 years, living in northeastern Iran, became its participants. During the observation period, 317 cases of esophageal cancer were recorded. For those who regularly drank very hot tea (75 C), the likelihood of developing this disease grew 2,4 times.
