Hemangioma is not cancerous. Hemangioma is caused by the weakening of the elasticity of the blood vessel wall and the malfunction of the blood vessel wall, resulting in excessive expansion of the blood vessel, which is greater than 1.5 times the normal diameter, forming a hemangioma. However, there is a possibility that hemangioma may form invasive hemangioma, that is, it may damage the surrounding tissues, such as trapezius hemangioma, which may cause certain invasion to muscles and bones, and in this case, hemangioma treatment may also be more troublesome. After treatment, hemangioma can also cause recurrence if there are residual tumor wall cells, which can lead to corresponding symptoms. For the treatment of hemangioma, it is important to evaluate and distinguish which type of hemangioma is involved, and then individualize the treatment.
