You're correct—tea itself is not cancerous. In fact, many studies suggest that certain types of tea, particularly green tea, may have health benefits due to their antioxidant properties. Compounds like catechins found in tea have been researched for their potential role in reducing the risk of some types of cancer.
However, it is important to consider the preparation and consumption methods, as some factors, such as high temperatures, can pose risks. For example, drinking very hot beverages has been linked to an increased risk of esophageal cancer in some studies. Always consult with healthcare professionals regarding dietary choices and their effects on health.
