Caffeine Drinks and the Risk of Cancer: A Review

Coffee and tea are among the most consumed beverages in the world. That is why the impact of coffee and tea consumption on health is very important. We reviewed papers that studied the link between coffee and tea and various cancers. We investigated the associations between various cancers and the consumption of coffee and tea. Coffee had the effect of reducing the risk of proximal tumor, liver cancer, oral and pharyngeal cancer, and prostate cancer. And herbal tea was effective in reducing the risk of distal colon cancer. However, ovarian cancer and colorectal cancer were not associated with caffeine beverage consumption.
