Primary liver cancer is the sixth most commonly diagnosed cancer worldwide, and because of its poor prognosis, it's the second leading cause of cancer death. But, researchers have found an important link between coffee consumption and liver cancer that can help diminish the risk. 

Researchers have found that drinking one cup of coffee daily was associated with a 20% reduced risk of hepatocellular cancer (HCC) - the most common form of liver cancer.

Drinking two cups of caffeinated coffee per day was linked to a 35% reduction in HCC risk, while the risk of HCC was halved with consumption of up to five cups of caffeinated coffee daily. 

The researchers speculate that the antioxidant, anti-inflammatory, and anti-carcinogenic compounds in coffee may help to explain the link between coffee intake and a lower risk of liver cancer.
