User:Mr. Ibrahem/Liver tumor

Liver tumors are abnormal growths within the liver. They may be benign or malignant (liver cancer). Symptoms may vary from none to an enlarged liver, abdominal pain, yellowish skin and eyes, vomiting, and itchiness.

Benign tumors include hemangiomas, liver cysts, hepatic granulomas, and hepatocellular adenomas. Malignant tumors may form within the liver or spread from elsewhere in the body (metastasis). The most common type to form within the liver is a hepatocellular carcinoma, with other types including bile duct cancer and hepatoblastoma. They may be discovered on medical imaging and confirmed by tissue biopsy.

Treatment depends on the type of tumor and may vary from none to chemotherapy, surgery, and liver transplant. Benign tumors of the liver are relatively common. Cancerous tumors of the liver are most commonly metastatic. The first descriptions of surgery for liver tumors date from the late 1800s; however, it was not until the 1970s that major advances were made.
