Symptoms that differentiate benign from malignant hepatic hemangioma are whether or not there are symptoms related to the rupture of the hemangioma, abdominal discomfort and so on. 1. Benign: hepatic hemangioma is a common benign tumor of liver, most patients have no obvious symptoms, usually found in ultrasound or abdominal surgery, there is no evidence that it may become malignant. It is mainly caused by congenital dysplasia, hormonal stimulation, etc. When the hemangioma enlarges to more than 5cm, patients may have symptoms such as abdominal mass, loss of appetite, nausea and pressure. 2. Malignant: generally if the tumor is larger than 25cm, it has certain influence on liver function, which may cause the hemangioma with obvious growth trend to rupture or produce obvious clinical symptoms, such as abdominal discomfort and pain. Therefore, most patients with hepatic hemangioma only need regular examination and close follow-up. If patients continue to have symptoms such as abdominal discomfort, it is recommended that they seek prompt medical attention to avoid delaying their condition.
