Does it matter if the hemangioma is not treated? This is a question that parents are very concerned about. Some parents think that hemangioma is painless and itchy, and if it doesn’t affect the beauty of the face, it is not harmful to the children’s body. Some parents hold a wait-and-see attitude towards hemangiomas, expecting that they will subside on their own. What will happen if the treatment of hemangioma is not timely? The following is the answer of experts. If hemangioma is not treated in time, it will cause the following effects to the patients: 1, hemangioma will leave scars, hyperplasia caused by disfigurement Infantile hemangioma occurring on the surface of the skin has the characteristic of proliferation, so it will lead to the expansion of malformed blood vessels, thinning of blood vessel wall, and it will be ruptured when the tumor is rubbed or stimulated, and the amount of bleeding will be bigger than the general trauma due to the tumor aggregating many malformed blood vessels and easier to be infected, resulting in traumatic injury. Because the tumor gathers a lot of malformed blood vessels, the bleeding volume is larger than the general trauma, and it is more easy to be infected, resulting in the wound not being healed for a long time, and then forming scars, or even enlarging and thickening, merging the facial features, and ultimately leading to disfigurement. 2, hemangioma will lead to hearing and vision impairment When infantile hemangioma occurs in ear, parotid gland and other parts, it can cause hearing impairment because the tumor blocks the ear canal or presses the normal tissues and organs such as auditory nerve.

When infantile hemangioma compresses and pulls the nerve tissue, it can cause neuropathic pain, muscle soreness and other symptoms. Thus, it will bring great inconvenience to patients’ study, life and work, and in serious cases, it can cause disability. 4, hemangioma will cause autism and other psychological disorders Infantile hemangioma occurs in the head, face, limbs and other exposed parts of the human body is the aesthetic center and the focus of vision, which directly affects the generation of first impression.
