Health Desk: 07 February 2018: Combined with excess alcohol consumption, scaldingly hot tea raises relative risk fivefold, says Chinese researchers

Cancer, which starts in the oesophagus, was already known to be linked to drinking alcohol and smoking, but those risks are heightened by the addition of daily cups of “burning hot” tea, scientists discovered.

Survival rates for oesophageal cancer are poor, with only about 15% of patients still alive five years after diagnosis in the UK. There are about 9,200 new cases diagnosed each year and 7,800 deaths.The tea warning emerged from China, where researchers followed the progress of 456,155 participants aged 30 to 79 for about nine years.

The team led by Dr. Canqing Yu at the National Natural Science Foundation of China found that high-temperature tea drinking combined with either alcohol consumption or smoking was associated with a greater risk of oesophageal cancer than hot tea alone.

“Compared with participants who drank tea less than weekly and consumed fewer than 15g of alcohol daily, those who drank burning hot tea and 15g or more of alcohol daily had the greatest risk for oesophageal cancer,” they wrote in the journal Annals of Internal Medicine.

Combined with excess alcohol consumption, hot tea raised the relative risk of developing the disease.
