Hot Tea Increases the Risk of Throat Cancer

Consuming hot tea in temperature of 70 degree Celsius or more likely can increase the risk of throat cancer. This is the conclusion of several researchers in Iran.

The research was broadcast in British Medical Journal, conducted in northern Iran, where a large amount of hot tea is consumed every day.

Osophagus cancer (esophagus) killed more than 500,000 people worldwide each year and “oesophageal squamous cell carcinoma” (OSCC) is the most common type.

Some earlier studies have related alcohol and tobacco with throat cancer, and generally, the disease attacks men than women. And now the hot drink is also suspected to cause cancer is such that, according to the study.

Golestan province in northern Iran has highest OSCC in the world, but the consumption of alcohol and low number of smokers, and women have the possibility of diagnosis with the same men.

Tea drinking habit is prevalent in the area, so the researchers set to investigate the possible relationship between tea drinking habits and risk of oesophageal squamous cell carcinoma.

They examined the tea drinking habits of 300 people who had a diagnosis of OSCC and a comparison group of 571 men and women of the same.

Almost all the participants drank black tea regularly, and on average, they consume more than one liter tea every day.

Compared with the tea warm or lukewarm nail on the temperature 65 degrees Celsius or less, drink hot tea, between 65 and 68 degrees Celsius, two time-related throat cancer risk, and drink tea on a very hot 70 degrees Celsius or more related with the increasing of eight times.

Same condition, compared with drinking the tea four minutes or more after pouring, drinking tea less than two minutes after pouring, related with the risk of five times higher.

“Our results show a strong increase in risk of OSCC related with the hot tea or very hot,” said the researchers. They suggest that people have to wait several minutes before drinking a glass of hot tea.

The report also support to the opinion that the injury because of hot temperature may cause “epithelium” cancer, despite how heat enhances tumor growth has not been known yet.
