What are the causes of hepatic hemangioma?

Hepatic hemangioma is one of the most common benign tumors of the liver. The causes of hepatic hemangioma mainly include congenital factors, abnormal hormone levels, and vascular malformations. Among these, congenital factors may result from abnormal development of liver blood vessels during the embryonic period; abnormal hormone levels, such as changes in female hormones or long-term use of oral contraceptives, may promote the growth of hemangiomas; vascular malformations may be caused by factors such as infections or impaired blood circulation. In daily life, it is difficult to prevent hepatic hemangioma definitively; however, maintaining a healthy lifestyle—including a balanced diet, moderate exercise, and regular medical checkups—can help monitor its presence and any changes. If a hepatic hemangioma is large or causing symptoms, prompt medical attention is recommended.
