Hemangioma is not hereditary. Hemangioma is a common benign swelling in the human body, which usually occurs during embryonic period, when the endothelial cells of blood vessels are altered and hemangioma occurs after birth, which is essentially different from the genetic disease that is often said to result from genetic inheritance. Hemangioma is not hereditary and is a benign mass that can be treated effectively. Some hemangiomas are lifelong patients, and they mainly cause cosmetic changes and changes in appearance, and most patients who need treatment come for treatment because of this. In some cases, the hemangioma may break down in the later stages of development, or may compress organs and cause symptoms. In any case, hemangioma is not a hereditary disease and will not be inherited.
