Most hemangiomas grow quickly within 6 months of the child’s age, and after 6 months they may stop growing and absorb slowly on their own, so that they do not leave traces in the end, unless the hemangioma is very large and may have local skin laxity after receding. Most hemangiomas are benign and do not affect anything other than aesthetics, and they do not break easily than other normal skin, and they do not bleed more than once. (Except for a few types of hemangioma) Therefore, the need for hemangioma treatment should be weighed against the pros and cons, depending on the age of the child, the location and type of hemangioma, and the rate of progression, etc. Choose the appropriate treatment method. Cryotherapy will definitely cause scars. The more advanced laser treatments can also control the growth of hemangioma to some extent without leaving scars or light scars. Isotope dressing treatment method is not advisable.
