Primary liver cancer, also known as hepatocellular carcinoma (HCC), is primarily caused by chronic liver damage and inflammation. The most common risk factors and causes of primary liver cancer include:
Chronic Hepatitis Infection: Chronic infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) is a major risk factor for liver cancer. These viruses can lead to long-term liver inflammation, cirrhosis, and ultimately increase the risk of HCC.
Cirrhosis: Cirrhosis is a condition characterized by scarring of the liver tissue. It can be caused by chronic alcohol abuse, chronic viral hepatitis, nonalcoholic fatty liver disease (NAFLD), or other liver diseases. Cirrhosis increases the risk of liver cancer.
Alcohol Consumption: Excessive and prolonged alcohol consumption can lead to liver cirrhosis, which in turn raises the risk of liver cancer.
Nonalcoholic Fatty Liver Disease (NAFLD): NAFLD is a condition in which excess fat accumulates in the liver, often due to factors such as obesity and metabolic syndrome. In some cases, NAFLD can progress to nonalcoholic steatohepatitis (NASH) and eventually liver cirrhosis, increasing the risk of liver cancer.
Aflatoxin Exposure: Aflatoxins are toxins produced by certain molds that can contaminate crops like peanuts, corn, and grains. Consuming food contaminated with aflatoxins over time can increase the risk of liver cancer.
Iron Overload: Conditions like hereditary hemochromatosis, in which the body absorbs too much iron, can lead to excess iron accumulation in the liver, increasing the risk of liver cancer.
Obesity: Obesity is associated with an increased risk of liver cancer, primarily due to its connection with fatty liver disease and metabolic changes.
Certain Genetic Conditions: Some inherited genetic conditions, such as Wilson's disease and alpha-1 antitrypsin deficiency, can increase the risk of liver cancer.
Smoking: Smoking tobacco has been linked to an increased risk of liver cancer, particularly in individuals with other risk factors like chronic viral hepatitis.
Exposure to Chemicals: Prolonged exposure to certain chemicals, such as vinyl chloride and thorium dioxide, is associated with an elevated risk of liver cancer.
Preventing primary liver cancer often involves managing risk factors. For example, getting vaccinated against hepatitis B, avoiding excessive alcohol consumption, maintaining a healthy weight, and practicing safe sex are strategies that can help reduce the risk of liver cancer. Additionally, regular medical check-ups and screening for liver disease are important, especially for individuals with known risk factors. Early detection can lead to more effective treatment options for liver cancer.

The main two causes of liver damage are alcoholism and hepatitis.
Scientists don't know what causes these tumors, although the noncancerous growths may be hereditary or present since birth.

A liver scan is usually ordered after blood studies and other imaging procedures have shown a liver abnormality. It is most often used to further evaluate masses or tumors. These may be benign growths in the liver, or cancer

Dysplastic nodules are abnormal growths in the liver that can sometimes be a precursor to liver cancer. They are characterized by changes in the structure and cells of the liver tissue. Monitoring and evaluation of dysplastic nodules are important to detect potential progression to liver cancer.
