The specific pathogenesis and causes of hemangiomas are not very clear. Their formation is usually related to multiple factors, and some children have congenital hemangiomas. For example, cases of congenital vascular malformations usually appear right after birth, but there are also some hemangiomas that form later in life, and even some adults may develop hemangiomas, so it is not necessarily congenital. If the hemangioma occurs in a part of the skin that is not particularly noticeable, it can be observed for the time being, as it does not cause serious harm to health. However, if the hemangioma is located in a more critical area, such as inside an organ, or if it develops very rapidly, it should be given adequate attention and examined and treated in a timely manner.
