The International Journal of Cancer has stated that drinking tea at very hot temperatures can lead to esophageal cancer.

The American cancer society has said about 17,650 people will be affected from this disease and 16000 will die from it. Meaning only 1,650 people will be saved.

The society says that approximately 20% of the people with esophageal cancer can go on to live 5 years after a diagnosis. Some factors can raise the risk of this dangerous cancer. They include being male and over the age of 55 along with having a diet concentrated in meat and low in fruits and vegetables.

Some researchers state that drinking hot liquids on a daily basis can also increase the risk of esophageal cancer. Mainly these studies asked the participants to remember and estimate the amount of tea they drank and exactly at what temperature. But such a research can have biased results. When the participants have to recall a series of events loss of memory can mix up the results. So a new study has aimed to correct this study by measuring the temperature selectively.

Very hot tea may raise risk by 90 percent

Dr. Farhad Islami conducted a research over 50,000 people along with his colleagues on people who were between the age of 40 to 75. The researchers followed them for a period of 10.1 years between 2004 to 2017. Out of this big ratio 317 developed esophageal cancer. They divided tea temperature in two categories “very hot” meaning a temperature over 60°C and cold or Luke warm tea at a temperature below 60°C.

The researchers also considered the time of pouring tea to drinking it that take a time for about 2-6 minutes. Overall the study concluded that drinking 700 ml of very hot tea increased the chances of the esophageal cancer by 90% compared with tea at a lower temperature i.e. cold temperature.

The authors warn scientists that they have to conduct a larger research to understand the dynamics behind this cancer.
