People who drink more than 700mL of tea daily and at a temperature greater than 60 ° C, are 90% more likely to develop esophageal cancer , says a new study.
The comparison was made with those who consume the drink less and at lower temperatures.
The study carried out in Iran had the participation of more than 50 thousand people during 10 years. At this time, 317 new cases of esophageal cancer were diagnosed in participants who were between 40 and 75 years old.
The research was published in the International Journal of Cancer .
This research reiterates the suspicion of some scientists that repeated injuries in certain places may influence the appearance of cancer.
Thus, as a specific temperature has been raised, it will be easier to understand the causes of esophageal cancer, as well as prevent its onset.
Esophageal cancer is common
According to the International Cancer Research Agency, esophageal cancer is the eighth most common type of cancer in the world and kills about 400,000 people a year.
In Brazil, according to the National Cancer Institute (INCA), 10,790 new cases of the disease were registered in 2018, with 8,240 in men and 2,550 in women.
This tumor is caused by repeated injuries due to smoke, alcohol, acid reflux and liquids (teas, mate, coffee) consumed very hot. The main risk factors for this disease are smoking and excessive consumption of alcoholic beverages.
