Hemangiomas are the most common benign tumor in infants, with an incidence of about 4-10%, and are usually more common in girls, about 3-5 times more common than in boys. It occurs more frequently in whites than in yellows and is less common in blacks. The incidence of preterm low birth weight (less than 1 kg at birth) is as high as 25%, while the incidence of twins is also higher. However, medically, Mulliken divided the originally defined hemangiomas into true hemangiomas and vascular malformations based on the biological behavior of the vascular endothelium and the origin of the abnormality. True hemangiomas are formed by abnormal proliferation of endothelial cells, whereas vascular malformations are anatomical malformations that occur without abnormal endothelial cell proliferation. This classification can be a good way to help us solve the question of whether and how to treat hemangioma. Therefore, parents should not panic when they find that their babies have hemangioma, and they should not rush to the doctor. The right treatment path can get the best treatment effect with the least cost. How to prevent hemangioma? 1, the prevention of neonatal mixed hemangioma, during pregnancy women do not abuse cosmetics, do not contraceptive pills, do not contain estrogen drugs and food. Some experts believe that the increase of estrogen content in human body will lead to the occurrence of neonatal mixed hemangioma. This is also because it can effectively avoid the increase of estrogen in the body of the newborn to avoid the occurrence of hemangioma, which can also help in the prevention of mixed hemangioma. Women who are pregnant with a baby should pay more attention to their daily diet and avoid eating cold and spicy food. If the normal development of the embryo is affected, it may lead to the occurrence of hemangioma. Hemangioma experts say that irritating foods can stimulate the development of the embryo, which is likely to lead to abnormal or malformed development of the fetus’ tissue.
