Patient's question:
My son is lively and adorable, but recently, he has developed a blue bump in his eyebrows. My friend told me it's a hemangioma. I was very worried upon hearing this and would like to ask what a hemangioma is and what causes it.Doctor's answer:
Hello! The factors that can cause hemangiomas include:1. Elevated estrogen levels. Estrogen receptors can induce the proliferation of vascular endothelial cells. In most clinical studies of capillary hemangiomas in children, it has been found that most children have high estrogen levels, indicating that the cause of neonatal capillary hemangiomas may be related to elevated estrogen levels.
2. The reasons for elevated estrogen levels in neonates may be related to the child itself. Some children have congenitally high estrogen levels, while others may have elevated estrogen levels due to high estrogen levels in the mother during pregnancy. Many factors in daily life can lead to elevated estrogen levels, such as diet, emotions, diseases, and medications.
3. Vascular malformations are caused by abnormal growth and development of blood vessels during embryonic periods. There are many reasons for abnormal growth and development of blood vessels, such as smoking, secondhand smoke, and alcohol consumption by pregnant women, which are among the causes of embryonic malformations. Additionally, drugs and radiation can also lead to abnormal growth and development of fetal blood vessels during the embryonic development process, resulting in the occurrence of hemangiomas later in life.
4. Family factors. Newborns with hemangiomas in several generations of their family are more prone to developing hemangiomas, indicating a susceptible genetic factor.
