Many hemangiomas, even with rapid growth, stay relatively small and cause no problems. Since they will eventually resolve, no treatment is needed. A significant minority of hemangiomas cause functional problems or threaten to leave permanent skin changes and require active treatment. Early in life, when hemangiomas have their greatest growth potential, it can be difficult to determine how big they will become, so your child may need to be seen in the clinic more often; as they get older this will be less often.
Reasons for treatment include: ulceration (breakdown of the skin), effect on important structures such as the eye, lip, or nose, psychosocial concerns, or when a hemangioma is so large or growing so rapidly that there is a real risk of leaving permanent scarring.
