TeaYou may heard lots of health benefits of tea, especially green tea, but new research shows if you drink too hot tea or coffee, you’re increasing the risk for esophageal cancer.

Doctors have long wondered whether very hot beverages increase the risk for squamous cell esophageal cancer. Considering the many things people eat and drink, studies have come back mixed on the hot drink and cancer connection.

Study has been showed that almost all people who live in Golestan, Province in Iran has high tendency have an abnormally esophageal. They are only drink two beverages, water and very hot tea. Of course water is not negative effect for our health, except if they’re contaminated. So, what else could make this happen?

Esophageal CancerA research team traveled to Golestan and documented the smoking, alcohol use and tea habits of 871 people in the region, 300 of whom were recently diagnosed with esophageal cancer. According to the study published in the British Medical Journal, the researchers found a strong link between the temperature at which people preferred their tea and the likelihood that they developed cancer.

So how hot is too hot for your throat? The scientists classified warm tea at anything below 149 degrees Fahrenheit. Hot tea, anything measured above 156 degrees Fahrenheit, doubled the risk of esophageal cancer. People who frequently had very hot tea, at 158 degrees Fahrenheit or above, had an eight-fold increased risk of esophageal cancer. At the very hot temperature, it would even hurt your finger, but they get used to it, you see.

Other Potential Culprits
TeaHot tea is not the only beverage linked to esophageal cancer. Drinking alcohol and using tobacco also ups the risk for cancer in the windpipe. But unlike booze and cigarettes, evidence in his study showed it's not the chemicals in the tea that matters.

Past studies comparing adjacent tea drinking areas in Linxian, China and areas surrounding the Golestan province in Iran, showed temperature affects cancer rates, according to data cited in Malekzadeh's article. Esophageal cancer numbers rose in regions where people preferred their tea very hot, and dropped where tea was served at a cooler temperature.

But gastroenterologists aren't entirely convinced of hot tea's effects.
I would not tell people to stop drinking hot tea at this point. Also there's diet, and you have to look at genetic factors that are involved, as well. Esophageal cancer, especially the squamous cell variety, is much more prevalent in Asian and South American countries than in the United States. So there's not a recommended screening for esophageal cancer in the U.S.
