Hemangioma is a type of benign tumor that can occur in many parts of the body, both superficial and visceral. The population of people who develop hemangiomas nowadays is children, and they are mostly found on the face. So is hemangioma dangerous? The answer depends on the situation. 1. The course of most hemangiomas can be divided into 3 major stages, namely appreciation, quiescence and remission. Therefore, it may take many years for the hemangioma to recede or even disappear completely as the child grows. These receding hemangiomas appear on the surface of the body and are bright red and strawberry-like. Although these receding hemangiomas are not dangerous to the child, a few of them can affect his or her appearance and can be mentally taxing. Therefore, most families who can afford it choose to have it removed, but not too early, because premature removal can leave traces of removal. The right thing to do is to observe whether the hemangioma is particularly prominent or aesthetically displeasing before undergoing surgery after consulting a doctor’s advice. In addition to the above-mentioned hemangiomas, there are also about 20% of hemangiomas that are commonly found in important body parts such as joints, nipples, anus, fingers, and even cranial and thoracic cavities, or that grow too fast and cannot be eliminated, thus affecting the corresponding functions and even endangering lives. Such hemangiomas are dangerous and should be treated promptly. There are 7 major types of treatment for hemangioma as follows: 1. Surgical excision: It is the first choice for the treatment of tumors, but it should be noted that the applicable symptoms should be mastered and not removed indiscriminately. 2.Cryotherapy: It is difficult to treat completely and has a high recurrence rate because of its high control difficulty, so it should be chosen carefully. 3.Radionuclide therapy: After using this technique for treatment, there will be the phenomenon of tissue atrophy or atrophic scar at the treatment site, which is recommended to be removed, otherwise there may be a risk of cancer, so the method should be generally avoided. 4.Injection therapy: Injecting specific drugs into the body of hemangioma to cause cell necrosis of this tumor is the focus of future research. 5.Laser treatment: It is effective for superficial and erythematous nevi. 6.Interventional therapy: It is more difficult to achieve the expected effect. 7.Copper needle therapy: It is rarely used now because of the corresponding toxicity caused by the absorption of copper atoms. However, no matter which type of treatment is chosen, it is necessary to understand clearly its possible risks and whether it is used on one’s child before proceeding. Whether or not hemangioma is dangerous varies from person to person, and not all of them are dangerous.
