Why do babies have hemangiomas?

In our lives, many babies have hemangiomas when they are just born. As the baby grows older, these hemangiomas may gradually disappear. Even if they do not disappear, their color will become lighter and they will gradually get better. In addition, the hemangiomas that babies have when they are born are generally benign. This kind of hemangioma will not make the baby feel uncomfortable. So why do babies have hemangiomas?

Hemangiomas are congenital benign tumors or vascular malformations. Most of them appear in the skin, subcutaneous tissue and oral mucosa of the face and neck, such as the face, tongue, lips, floor of mouth and other tissues. Hemangiomas in deep muscles, bones or parotid glands are also not uncommon. Hemangiomas are common in infants at birth or shortly after birth. It is a common disease among infants and young children, with an incidence rate of 1% to 2%, and the incidence rate in female infants is three times that in male infants. Adults may also experience symptoms of hemangiomas. Some may develop during infancy as they grow and develop, while others may appear as tumors deep in the face grow larger. The most common ones in infants and young children are: port-wine stains, strawberry hemangiomas, cavernous hemangiomas, and mixed hemangiomas. Generally speaking, the natural process of hemangioma goes through three stages: growth, dormancy, and regression. According to clinical statistics, 91.9% of hemangiomas can regress naturally with age, and the skin appearance can return to normal after regression. Of course, some hemangiomas will not disappear and may exist for life. It is currently advocated that hemangiomas should be treated actively to prevent their area and volume from continuing to increase, which would increase the difficulty of later treatment. It is recommended to closely observe the growth of hemangioma. If it does not disappear or shrink, go to the hospital for timely examination if necessary to grasp the best time for treatment.

Some hemangiomas grow with age and will never appear in your life. If they are not treated early when the tumor is small, you will have lifelong regrets. Hemangiomas are more common in infants and young children. Whether they are children or adults, they should be detected and treated early. No matter which treatment method is chosen, it should be performed when the tumor is small. Once the tumor grows larger, it will increase the difficulty of treatment and affect the effectiveness of treatment. Therefore, you should take your child for examination as soon as possible to confirm the diagnosis and decide how to treat it.

A very small number of them, such as hemangioendothelioma, angiosarcoma, and hemangioblastoma, are malignant tumors, accounting for about 5%. Hemangiomas are divided into primary and secondary types. Primary hemangiomas account for 75%, that is, they are congenital and fetal, and are formed due to abnormal proliferation of the vascular network in the human embryonic period and are present at birth; secondary hemangiomas mostly occur in infancy and the cause is still unclear.

Hemangiomas can occur in various parts of the human body, such as the face, limbs, chest and abdomen, as well as the brain, liver, chest, and abdominal cavity. Hazards of hemangioma: bleeding, infection, ulcers, compression, and destruction of tissue and organ functions and morphology, which can affect appearance and human growth and development.

2. What is the cause of infantile hemangioma?

①Genetic factors. ② During pregnancy, women are exposed to environmental pollution, drug stimulation and adverse factors, which lead to abnormal proliferation and expansion of the vascular network within 3 months of the embryo. ③Environmental pollution and food factors. ④Traumatic factors.
