People kick start their day with a piping hot tea, while some feel relax after having it. But it can be dangerous sometimes. A new study, published in the Journal of Cancer, those who drink tea at 60-degree Celsius temperature or higher had a 90% higher risk of esophageal cancer. Tea lovers who drink more than 700 ml of tea per day at higher temperatures had a doubled risk of fatal disease. Researchers studied more than 50,000 people for a decade. They decided to notice people in Golestan, a province in Iran, where it is common to drink piping hot tea.
Scientists from the American Cancer Society discovered earlier that there is a link between esophageal squamous cell carcinoma (ESSS) and tea. But they did not have the precise knowledge of the impact of various temperatures. The new study discovered that those who sipped tea at temperatures higher than 140 degrees Fahrenheit were associated with a 90% higher risk of getting ESCC. The fact behind the finding is that sipping piping hot tea harms esophagus. It results in burning and irritation in the throat. Dr. Daniela Molena, director of Memorial Sloan Kettering’s Esophageal Surgery Program, hot sips and beverages could destroy the internal coating of the esophagus. As a part of internal recovery, our body keeps generating new cells to repair it. But if something goes wrong, there is a high probability that the healthy cells may turn into cancer cells.
On the other hand, the National Cancer Institute says, it doesn’t mean that tea is harmful. In fact, the organic chemicals and antioxidants in green tea could help to reduce the risk of cancer. Researchers say the concern is not tea, but its temperature is in question. According to the International Agency for Research on Cancer, esophageal cancer is a common type of cancer in the world. It kills around 400,000 people every year. The American Cancer Society roughly estimates in 2019 the U.S. will have 17,650 new cases of esophageal cancer. The researchers concluded as the hot beverages do not offer any health benefit. Thus it is better to let them cool and then drink. Though they noted more study is required in the area for better perception.
