• History of Hepatitis B or C – Worldwide, these conditions are the most common causes of liver cancer.

• Abuse of alcohol – Drinking more than two drinks of alcohol a day over the course of many years can increase the risk for cancers.

• Aflatoxin – Aflatoxin is “a harmful substance made by certain types of mold ... can form on peanuts, corn, and other nuts and grains ...The United States has safety measures limiting aflatoxin in the food supply.” (National Cancer Institute)

• Iron storage disease
• Cirrhosis
• Obesity and diabetes
