1. Hemangioma of liver
The most common type of benign or non-cancerous liver tumor, hemangioma, originates in blood vessels. Most hemangiomas of liver cause no symptoms and thus, do not need treatment. But in cases where it shows symptoms such as bleeding, liver hemangioma treatment may include medication such as corticosteroids, cutting off blood supply of the tumor, or surgery to remove the hemangioma.
2 Hepatic Adenoma
This is a benign tumor that starts from hepatocytes (the main type of liver cell) and usually causes no symptoms. These hormone-induced liver cell adenomas very often do not need any treatment, but some, at the later stage, may cause symptoms, such as loss of blood, pain or lump in the abdomen, etc.
Though non-cancerous, inflammatory hepatic adenoma has a small risk that it could eventually develop into liver cancer, therefore, it is recommended to remove the tumor through a surgical procedure.
3. Focal Nodular Hyperplasia
Focal nodular hyperplasia (FNH) of liver is a tumor-like growth made up of several cell types (hepatocytes, bile duct cells, and connective tissue cells). Although benign, this is the second most prevalent tumor of the liver. It is generally asymptomatic and is often found incidentally.
