Benign tumors that cause liver lesions include hemangiomas, states the San Francisco Center for Liver Disease. These are the most common benign liver tumors. They are often asymptomatic and do not need treatment. Other benign lesions are focal nodular hyperplasias. These tumors are also often asymptomatic and do not bleed or turn into liver cancer. However, adenomas may cause abdominal discomfort, bleed and become malignant. Fortunately, they are rare.

Hepatocellular liver cancer is a malignancy that arises in the liver itself and is not the result of a metastasis from another organ, notes WebMD. People who develop this type of liver cancer usually have birth defects, are alcoholic or have a long standing infection caused by hepatitis B and C. They may also suffer from cirrhosis and hemochromatosis, a condition in which the liver stores too much iron.

Hepatitis is a liver inflammation usually caused by a virus, says the World Health Organization. The main viruses are A, B, C, D and E, and B and C are especially dangerous. These viruses can be contracted through intimate contact or by eating or drinking contaminated food and water.
