Whether neck hemangioma is dangerous or not is related to the pathological nature of hemangioma, the growth site of hemangioma, the growth speed and so on, and cannot be generalized. Whether hemangioma in the neck is dangerous or not is related to the nature of hemangioma pathology. Benign hemangioma generally does not affect physical health, while malignant hemangioma may spread, which in turn may cause corresponding symptoms and need timely treatment. Whether hemangioma in neck is dangerous or not also depends on the location of hemangioma growth, the speed of hemangioma growth, and the relationship between hemangioma and neighboring tissues and organs. If the hemangioma in the neck is superficial and small in size, there is usually no obvious danger. If it is larger and invades deeper, the risk of rupture and infection is higher. If the hemangioma grows faster and is closer to the jugular vein, carotid artery or trachea, it may compress the blood vessels and trachea and cause corresponding symptoms. Drugs for treating neck hemangioma include topical application drugs such as propranolol ointment, imiquimod cream, etc. Oral propranolol, prednisolone, sirolimus and other drugs can also be taken to improve the symptoms, and the drugs need to be selected under the guidance of the doctor. For neck hemangiomas with pressure symptoms or spread, the hemangiomas can be removed by surgical treatment. After treatment, benign cervical hemangiomas can subside significantly, and junctional or malignant cervical hemangiomas can control the progression of the disease and improve the prognosis of the disease.
