What causes hemangioma and what are the dangers

Most hemangiomas occur on the patient's body surface, affecting the patient's appearance and causing the patient to suffer psychological pressure from the strange looks of others. Not only that, some dangerous hemangiomas will also pose a threat to the patient's physical health and even life. Therefore, if you find that you have a hemangioma, you must check, identify and treat it in time.

What is a hemangioma?

Hemangioma refers to a benign tumor that occurs in vascular tissue. It is formed due to the misconfiguration and tumor-like proliferation of vascular tissue. It is divided into primary and secondary types, of which primary accounts for 75% and secondary accounts for about 25%. Most secondary cases occur in infancy, and a few are discovered in adulthood. The cause is still unclear. Primary or congenital hemangiomas are formed by the proliferation of the vascular network during the human embryonic period. They are present at birth and may be asymptomatic when the hemangioma is small. Hemangiomas can occur in various parts of the body and grow on exposed parts of the face and limbs, affecting appearance. It compresses and destroys the functions and morphology of surrounding tissues and organs to varying degrees, affecting the growth and development of the human body. Some may experience repeated bleeding and infection, and a very small number of people may develop malignant changes or even be life-threatening.

Hemangiomas can be essentially divided into two types: one is a vascular malformation (hamartoma) caused by abnormal vascular development during embryonic development, excessive vascular development or abnormal differentiation; the other is a true tumor caused by abnormal proliferation of vascular endothelial cells.

Hemangioma pathology

The incidence of hemangioma in newborns in China is about 3-8%. At least 300,000 newborns suffer from hemangioma every year. The causes can be divided into two types:

1. Vascular malformations caused by abnormal vascular development during placental development, overdevelopment or abnormal differentiation of blood vessels.

2. Tumors caused by abnormal proliferation of vascular endothelial cells, 80% of which are congenital.

There are many causes of hemangioma: genetic factors, external environmental pollution during pregnancy, drug stimulation and adverse factors that lead to abnormal proliferation and expansion of the vascular network in the placenta within 3 months to form hemangiomas. In addition, environmental pollution, food factors and traumatic factors can all lead to the formation of hemangiomas.
