Liquid nitrogen freezing of hemangiomas is effective. Hemangioma is a benign tumor, divided into primary and secondary types, both types of tumors are more sensitive to liquid nitrogen freezing. Research shows that liquid nitrogen freezing can make local skin and blood vessels ischemia and necrosis, so as to achieve the purpose of removing tumor cells. At the same time, because the fibrous tissue within the arteries is able to tolerate freezing, there is little or no damage to the skin. Although liquid nitrogen freezing hemangioma has certain curative effect, but for some special types of hemangioma, such as spongy or mixed hemangioma, but also combined with surgery and other methods of treatment, in order to achieve better results. For some larger hemangiomas, liquid nitrogen freezing treatment is also not suitable.
