The American Liver Foundation is promoting Liver Cancer Awareness Month in Nevada this October by educating the public on the functions of the liver in the body and risk factors for liver disease. There are approximately 30 million individuals in America who have some type of liver disease, including hepatitis A, B and C, but many are undiagnosed or improperly diagnosed. Three out of four people in the United States who have hepatitis do not know they are infected, and it is the most common cause of liver cancer.
