Does Drinking Hot Tea Increase Esophageal Cancer Risk?

Posted February 07, 2018

The authors of this prospective cohort study analyzed high-temperature tea drinking, alcohol use, and smoking for possible associations with risk for esophageal cancer.

Previous studies have hinted that drinking hot tea or coffee daily could increase the risk of oesophageal cancer, including a 2016 study by International Agency for Research on Cancer (IARC).

"These findings suggest that abstaining from hot tea may be beneficial for persons who drink alcohol excessively or smoke", researchers said in a press release from the American College of Physicians.

According to a new study in Annals of Internal Medicine, slurping scalding tea can increase your chances of esophageal cancer, especially when combined with being a regular smoker and alcohol drinker. The researchers excluded people who were previously diagnosed with cancer or who reduced tea drinking, alcohol intake or cigarette smoking. Cancer beginning in the esophagus has a survival of only five years after the initial diagnosis.

But even those who don't touch or cigarettes appear to have a higher risk, researchers warned, but they stressed more tests are needed to assess how damaging it could be.

In the end, the researchers indicated 1,731 cases of esophageal cancer.

The researchers who carried out the study were mostly from China (Peking University, Beijing Institute of Technology, Suzhou Center for Disease Control and Prevention, and the China National Center for Food Safety Risk Assessment) and the University of Oxford in the UK. It is often caused by repeated injury to the esophagus because of smoke, alcohol, acid reflux, and possibly hot liquids as suggested by the new study.

This isn't the first time drinking very hot tea has been associated with esophageal cancer. If you only drink hot tea, don't worry. China is among the countries with the highest rates of esophageal cancer.

The study was only observational, so a cause-and-effect link can not be determined.

The research showed that Chinese men are specifically more likely to smoke and drink alcohol along with having tea at very high temperatures.

The study, the largest of its kind, followed close to 500,000 adults in China over an average of 9½ years.

People were only asked about tea, alcohol and tobacco consumption at the start of the study. For the people who find it hard to do so, avoiding burning-tea is the alternative solution. It is also by far, the biggest consumer of tea in the world.
