Liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass that occurs in the liver. A liver hemangioma is made up of a tangle of blood vessels. Liver hemangioma is sometimes called hepatic hemangioma or cavernous hemangioma.
Most cases of liver hemangioma are discovered during a test or procedure for some other condition. Most people who have a liver hemangioma never experience signs and symptoms and never need treatment.
It may be unsettling to know you have a mass in your liver, even if it's a benign mass. However, there's no evidence that an untreated liver hemangioma can lead to liver cancer.
