The best time to treat infantile hemangioma is mainly related to the type, location and size of the hemangioma, and cannot be generalized. Infantile hemangioma is one of the more common diseases in pediatric dermatology. If the hemangioma is superficial or hidden, and the tumor is small and does not affect the child’s image, it usually does not require special treatment and can be reviewed regularly. As children grow older, some hemangiomas may stop growing or may shrink until they fade away. If the hemangioma lesion is large or tends to increase in size and affects the normal life of the child, treatment should be considered and can be performed after the child is 1 month old with appropriate laser or cryotherapy. Because of suction, when infants develop hemangioma, they can visit pediatric dermatology every 3 months or so to be examined and evaluated by a doctor for the growth of hemangioma to decide the next step of treatment.
