Hepatic hemangioma growing violently in a month is not liver cancer, and there is no evidence that hepatic hemangioma has the possibility of malignant transformation. Hepatic hemangioma is a relatively common benign tumor of the liver, which usually has no clinical symptoms and may be caused by congenital developmental abnormalities or may be related to hormonal stimulation. The etiology and pathogenesis of hepatocellular carcinoma are still unclear. It is believed that it is mostly related to hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, aflatoxin, drinking water contamination, alcohol, cirrhosis, sex hormones, nitrosamines and other factors, not related to hepatic hemangioma. If liver hemangioma grows violently within one month, it may develop into huge hemangioma (10-15cm) or even extra large hemangioma (>15cm), which requires active surgical treatment or hepatic artery embolization to prevent hepatic hemangioma from rupture and bleeding, causing shock symptoms and endangering life. Patients with hepatic hemangioma should be reviewed regularly to observe changes in their condition and deal with abnormalities in a timely manner.
