Neonatal hemangiomas are not dangerous. Hemangiomas are benign tumors that occur mostly in infancy and childhood, and their pathogenesis is due to congenital vascular malformations. Many hemangiomas have the possibility of self-healing, and many hemangioma babies will gradually shrink and disappear within 5 years of birth. If your baby’s hemangioma grows bigger and bigger and affects your daily life, you need to go to the hospital for further examination and treatment. At present, you can use topical medication, laser surgery and traditional open surgery to treat the tumor. If the baby’s hemangioma grows in a special location, such as lips, perianal, orbital, nasal cavity, etc., the treatment is relatively more troublesome, but also need to be treated with surgery or laser therapy as soon as possible.
