There is no special requirement for age, and the time of treatment should be early rather than late; early treatment can intervene the further development of hemangioma from skin to deep as early as possible, and the course of treatment is short, the effect is good, the dose of radiation is also less, and the phenomenon of pigmentation disappears also early. For hemangiomas in special parts such as eye corners, nostrils, external auditory canal, etc., because it is difficult for the dressing device to stick closely to the tumor lesion, the treatment is more difficult, so it can be treated with discretion; for hemangiomas in sensitive, folded or easy to rub parts such as oral cavity, perineum, head and neck, armpit, N nest, etc., the dosage should be on the low side; for the hemangiomas on the facial part, it is necessary to treat the treatment with special care and caution, to avoid the after-effects of skin damage caused by excessive irradiation.
