What is the cause of hemangioma in newborn babies?

Hemangiomas in newborn babies may be related to genetics, hormone levels, and abnormal vascular development. They are usually benign and can be managed through observation, drug therapy, or surgical intervention. Congenital hemangiomas are mostly caused by abnormal vascular development during the embryonic period, which is partly related to genetic factors. The intrauterine environment during pregnancy, such as hormone fluctuations, may also affect the formation and growth of blood vessels.

1. Genetic factors are considered to be one of the important causes of hemangiomas in newborn babies. Babies with a family history of hemangiomas may be more susceptible to the disease than babies without a family history. This type of hemangioma usually appears at birth or within a few weeks after birth, with varying sizes and shapes, but most of them will disappear on their own within a few years.

2. Hormone levels, especially female hormones such as estrogen, are believed to be related to the formation and development of hemangiomas. This phenomenon is more common in female babies, especially when hormone levels fluctuate greatly during the mother's pregnancy or in the early stages after the baby is born.

3. Abnormal vascular development is another major cause. During embryonic development, errors may occur in the formation and distribution of blood vessels, leading to the occurrence of hemangiomas. These abnormalities may be mild capillary dilation or complex arteriovenous malformations, requiring different treatments depending on the specific situation.

4. For hemangiomas with minor symptoms, doctors usually recommend observing their natural development, because many infants' hemangiomas will gradually disappear with age. During the observation period, parents should take their babies for regular medical examinations to ensure that the hemangioma does not worsen or cause other problems.

5. In terms of drug treatment, commonly used drugs include beta-blockers such as propranolol, which can effectively reduce the size of hemangiomas, especially those located on the face or other important parts of the body. In addition, steroid drugs such as prednisone are also commonly used to reduce the growth of hemangiomas.

6. Surgical treatment is suitable for infants whose hemangiomas are large or located in critical areas. Laser surgery and cryosurgery are two common methods. Laser surgery destroys hemangioma tissue through high-energy beams, while cryosurgery causes hemangioma tissue necrosis through low temperatures. These surgical methods need to be performed under the guidance of professional doctors to ensure safety and effectiveness.

Although most hemangiomas in newborns are benign, if they show rapid enlargement, bleeding or infection, parents should seek medical attention in time and seek help from professional doctors so that appropriate treatment plans can be developed as soon as possible to ensure the healthy growth of the baby.
