Hemangioma is a benign tumor that rarely becomes malignant. Although they are benign tumors, most hemangiomas will cause great harm to the human body if they are not treated in time. However, many friends have relapsed after timely treatment. We will give a detailed introduction on the reasons for recurrence which are of great concern to our patients. The reason for the recurrence of hemangioma after treatment is: 1. Many patients with hemangioma have adopted many kinds of treatment methods, but after treatment, recurrent attacks, and for a long time can not get a thorough and effective treatment, so many patients lose confidence in treatment, and even serious recurrence interval is getting shorter and shorter. Hemangioma is a kind of embryonic developmental abnormality, the incidence of which is relatively small, and few large hospitals have set up special hemangioma departments, so there are relatively few specialists in clinical hemangioma treatment. Many friends do not know which department to go to for hemangioma, so often the doctors do not have special research and treatment experience for hemangioma, resulting in uneven levels of hemangioma treatment, and the treatment methods are not professional enough and not targeted, resulting in a high chance of recurrence after hemangioma treatment. 2, clinical findings, many patients with hemangioma, originally hemangioma area is not so large, but after some inappropriate treatment methods, promote the speed of growth of hemangioma area, but make the original condition more serious. If treatment is not continued, the disease will progress quietly and lead to recurrent attacks and persistent treatment. Many pediatric patients continue to have the disease as adults, and the long course of the disease causes the number of malformed vessels to increase and the scope of the hemangioma to become more and more extensive, leading to a variety of complications after the sequelae. To sum up, to avoid recurrence of hemangioma after treatment, we must pay attention to the choice of doctors. A good doctor must have rich clinical experience in treatment, and for hemangioma specialists, they will have targeted and mature treatment plans for different types of hemangiomas, different parts and different growth patterns. For example, many doctors choose surgery to treat hemangioma, but an experienced hemangioma specialist will consider from all aspects whether the patient is really suitable for surgery and what drawbacks will arise after surgery, and will combine other clinical treatment options to choose the most perfect treatment plan. As far as the treatment of hemangioma is concerned, most experienced hemangioma experts will not choose surgery because the demarcation line between hemangioma and surrounding normal tissues is not clear and surgical excision is not clean, which not only cannot cure hemangioma completely and effectively, but also surgery will produce more broken ends of deformed blood vessels, resulting in fast recurrence and growth of hemangioma. In addition, it is important to emphasize here that throughout the hemangioma treatment process, patients (or family members) should work closely with their doctors and follow up regularly to establish a partnership that will allow doctors to fully grasp and assess the patient’s condition and decide and adjust the treatment plan. Therefore, when a patient feels doubtful and confused about the disease, please confide in the competent doctor in time to obtain helpful guidance and advice.
