It is possible for a hemangioma to come back after treatment. Hemangiomas are caused by genetic problems or problems with the walls of the blood vessels, resulting in over-expansion of the blood vessels, which can lead to the formation of hemangiomas. Some hemangiomas have malignant tendency and may recur after treatment, and the chance of recurrence is relatively high. For example, trapezoidal hemangiomas still have certain effects on the organism after recurrence, and may invade the skin, fat, muscle, and bone, so it is necessary to formulate an individualized treatment plan for this kind of hemangioma to avoid recurrence after surgery and to provide comprehensive treatment for hemangiomas. After the treatment, it is also necessary to have regular checkups to observe whether there is any possibility or tendency of recurrence of hemangioma. If the recurrence of hemangioma is found, early treatment is also very necessary.
