Preliminary analysis revealed that compared to subjects who drank tea <1 time per week, those who consumed >4g of tea daily had an overall cancer risk increase of 26%, a 62% increase in lung cancer risk, and a 29% increase in stomach cancer risk.
However, further analysis found that tea drinkers often also have habits such as smoking and alcohol consumption, both of which can increase the risk of cancer.
Moreover, many Chinese people like to drink hot tea, and hot tea can scald the esophageal mucosa. Repeated scalding can significantly increase the risk of esophageal cancer.
After excluding factors such as smoking and alcohol consumption, the relationship between tea drinking and the risk of cancer significantly decreased.
