How many people in the population get hemangiomas of the liver?

Liver hemangioma usually refers to hepatic cavernous hemangioma, the incidence rate of which can reach 0.4-20% in the population, and it is one of the common benign tumors of the liver. Commonly found in middle-aged women, the tumors are mostly solitary or multiple. When the tumors are small, they do not have any symptoms, but if they increase in size and cause compression symptoms (epigastric discomfort, abdominal pain, abdominal distension, etc.), they need to be treated surgically. Hepatic cavernous hemangioma grows slowly, usually without any symptom for several years, at this time there is no need for treatment, and ultrasonic examination can be performed 1~2 times a year to observe the changes in the growth of the tumor. If clinical symptoms appear or the diameter of the tumor is >10 cm, especially when the tumor is located at the edge of the liver, such tumors are prone to rupture leading to bleeding, and surgical resection should be chosen. If the diagnosis of hepatic hemangioma is confirmed, one should seek medical treatment to improve relevant examinations and choose further treatment options (follow-up observation or surgical treatment) under the guidance of physicians.
