Still another study (a major one) suggests that coffee lowers the risk of liver cancer (even in consumers of alcohol). Per the article:
Liver cancer is the second-leading cause of cancer deaths worldwide. But now - along with multiple sclerosis, Parkinson's disease and Alzheimer's disease - the risk of liver cancer can be reduced by coffee consumption. Researchers are unsure why coffee seems to benefit these conditions, they admit, but according to this study - rates of cancer were 29 percent lower in coffee drinkers when compared with non-coffee drinkers....Scientists from the World Cancer Research Fund International's Continuous Update Project (CUP), in partnership with the American Institute for Cancer Research, undertook the research, which looked at 24,500 cases of liver cancer....The authors of the study looked at data from 34 different research initiatives involving more than 8.2 million people from around the world.
