Liver hemangioma

A liver hemangioma is a benign (noncancerous) growth in the liver formed by a cluster of blood vessels. It is also known as a hepatic hemangioma or cavernous hemangioma. Most liver hemangiomas are discovered incidentally during imaging tests performed for other reasons. They are very common—affecting up to 20% of people—and usually cause no symptoms. In the vast majority of cases, no treatment is required. Although finding a mass in the liver can be concerning, liver hemangiomas are not cancerous and do not turn into liver cancer. There is no evidence that leaving a liver hemangioma untreated increases cancer risk. In simple terms, a liver hemangioma is a harmless collection of blood vessels within the liver that typically does not affect health or liver function.
