Infantile hemangioma is a common benign tumor or vascular malformation lesion in infancy. The development period of this disease is within six months, and many doctors advocate that early detection and early treatment. As the affected child grows, the hemangioma expands, growing faster and increasing in size, which can greatly increase the difficulty of treatment. So parents need to take active and effective treatment measures before their child’s hemangioma increases in size, otherwise it may induce more serious sequelae. However, for the families of the children, they still don’t know when it is more appropriate to treat the hemangioma. They are afraid that the child will not be able to bear it if the treatment is too early, and they want to wait until the child grows up, but they are worried that the hemangioma will miss the best time and grow bigger and bigger. So, when is the best time to treat infant hemangioma? The treatment time for hemangioma cannot be determined by age, but the development of hemangioma is closely related to the growth of age. Most of the hemangiomas will expand with the growth of children, and may even invade joints and bones, which may cause organ dysfunction. According to a large number of previous medical studies, hemangioma grows rapidly after birth, continues to grow and increase, and invades the surrounding normal skin and deep tissues for 6-10 months, which is called the growth period; later on, its growth rate will be slow and stable, but still faster than the development process of the child, and the time varies, which is called the stable period; generally, after the child grows up to 1 year old, very few capillary hemangiomas may begin to degenerate. After the child reaches the age of 1 year, a very small number of capillary hemangiomas may partially degenerate, and a very small number of patients may degenerate and recede after the age of >2 years, which is called the degenerative phase. From this study, we can see that hemangioma is a growth period before the age of one year, and if it develops into the surrounding normal skin and tissues and organs, it will affect its normal function and increase the difficulty of treatment. In some cases, the growth rate of the child will exceed the normal development of the child before 6 months of age, so we should intervene or control the hemangioma before it grows. The above is the specific introduction of “when is the best time to treat infant hemangioma”, hemangioma cannot disappear automatically, so it should be treated at the best time, that is, before the age of one. However, what should be done if the child misses the best treatment time and the hemangioma grows to a larger size after the age of one? Parents are reminded that if their child misses the best time for treatment, parents should not delay any longer and should take their child for regular treatment in time. At this time, treatment is not ineffective, but it will be more difficult to treat, but as long as effective treatment is taken, the ideal treatment effect can be achieved. As long as the most targeted treatment is taken at the best time, it can greatly reduce the difficulty and risk of treatment, as well as the pain of the child, and control the sequelae and complications in time, it can be completely cured without regret. At the same time, parents should help their children to develop a good diet and lifestyle habits, which will help the recovery of the child’s condition. We wish you a speedy recovery!
