Primary liver cancer is generally not certain to be hereditary, but it may be somewhat related to genetics. For example, there are often phenomena of family and regional clustering of liver cancer. Current research believes that primary liver cancer, commonly referred to as liver cancer, is the result of a combination of factors, closely associated with hepatitis virus infection, aflatoxin infection, and contaminated drinking water. Common scenarios include hepatitis B virus infection leading to hepatitis B followed by cirrhosis, which can further develop into primary liver cancer. Also, long-term alcohol abuse leading to alcoholic cirrhosis can also result in liver cancer.
