According to a survey, the risk of liver cancer in people who drink 1-2 cups of coffee per day is one half of the risk of developing liver cancer in people who do not drink coffee at all. The risk of developing liver cancer in people who drink more than 5 cups of coffee per day is completely without coffee. One-fourth of the risk of developing liver cancer.
