Whether surgery is recommended for cavernous hemangioma is related to the size of the hemangioma, its growth rate, and the presence of uncomfortable symptoms. If the diameter of cavernous hemangioma is within 5cm, the size is small and the number is small, mostly small lumps, and there is no obvious symptom or the symptom is mild, usually surgery is not used for treatment. It can be handled by non-surgical methods, and then pay attention to regular checkups. If the tumor is properly controlled and does not continue to grow, or grows slowly, surgery may not be necessary. If the diameter of cavernous hemangioma is larger than 5cm, the mass is obvious, and the patient has obvious discomfort symptoms such as pain, it is generally recommended to remove the cavernous hemangioma by surgery. For infantile hemangioma, clinically, drugs, injection of vascular sclerosing agent, laser and other conservative treatments are the mainstay, generally not surgical treatment. However, if the tumor grows in a hidden part of the trunk, surgery can be used to remove the lesion completely. If the patient suffers from cavernous hemangioma, it is recommended to go to the hospital for a detailed examination to determine the specific situation, and carry out symptomatic treatment under the guidance of the doctor to avoid delaying the condition.
