Hepatic hemangioma is a common disease. Usually, hemangioma does not grow or grows very slowly, and some patients have 2cm in the past 1-2 years and still 2cm after 2 years when they are reviewed. However, some patients have hepatic hemangiomas that grow 1-2 cm per year, and some patients suddenly grow from 2-3 cm to 10 cm within one year or six months, which is rare. There is another kind of patients, namely pregnant women, whose hemangioma grows faster due to endocrine changes, but it can be controlled without worrying.
