There is a lack of authoritative statistics on the time for adult hemangiomas to go away on their own, and they generally do not go away on their own and need to be actively treated. Most adult hemangioma will not subside by itself, if the patient’s hemangioma symptoms are more obvious, need to actively consult the doctor, don’t wait for self-healing. Avoid scratching or squeezing the lesion at the site of hemangioma to avoid causing breakage, infection, bleeding and injury. A small portion of benign hemangiomas can disappear on their own with the delay of time, but the time of self-healing cannot be counted. Junctional hemangioma or malignant hemangioma has the possibility of recurrence, and malignant hemangioma can be metastasized. Adults with hemangiomas should not treat themselves or wait for them to disappear on their own, but should actively consult the doctor and follow the standard treatment under the guidance of the physician’s interview, and should not use medication on their own.
