Hemangioma is a kind of benign tumor with high prevalence in pediatric period, accounting for about 22% of the total number of defects in children with congenital disabilities (including defects that appear only months and years after birth), and it is still increasing year by year, and has become the “number one killer” of birth defects in newborn babies. The physical and psychological impact and damage to the affected children cannot be ignored. In order to prevent and treat this disease more comprehensively, it is extremely important to actively understand and master the etiology of hemangioma. So, what are the main factors that induce hemangioma in life? At present, the causes of hemangioma can be divided into primary and secondary, most of which are primary, accounting for 75%, but the influence of the acquired environment can also induce the disease, and the key to stay away from hemangioma is to avoid the triggering factors. The following factors are the main causes of hemangioma: 1. Pregnancy damage During pregnancy, women are affected by various drugs, cosmetics, radiation, chemicals and other factors that can become the cause of hemangioma. In addition, pregnant women suffering from diseases such as anemia and diabetes during pregnancy, or infected with viruses, such as influenza, rubella or certain kinds of injuries may be the cause of hemangioma. The occurrence of disease and the dietary environment have a certain relationship, and the change of dietary habits and living environment is one of the factors that lead to the high incidence of hemangioma. For example, some people will eat artificially farmed seafood and meat products, and so on, and excessive intake of hormones may induce this disease. Genetic factors Infant hemangioma has a certain probability of heredity, but only a very small percentage of patients with hemangioma will inherit it. Trauma is one of the main causes of infantile hemangioma, but it is not common in clinical practice. There are two possibilities for the disease caused by trauma, one is simply a vascular malformation caused by trauma, and the other is that the child suffers from the disease itself, and the symptoms only appear after the stimulation of trauma. 5.Other lesions Some patients have some lesions in their own bodies, and the stimulation of various disease-triggering factors can trigger the mutation of the body’s vascular tissue to form hemangioma. The above is a brief introduction to the causes of hemangioma, and these are not the only factors that cause hemangioma, there are also some rare factors, patients or parents must pay attention to and observe the growth of the affected children in life, through the understanding of the causes of the development of hemangioma, usually actively do a good job in the prevention of hemangioma health care work, and treatment of hemangioma disease for the cause, in order to stay away from the disease and restore health. The only way to keep away from the disease and restore health is to treat the cause.
