Multiple clinical studies and case reports demonstrate that hemangiomas, particularly infantile hemangiomas, are successfully treated using medications such as beta-blockers (e.g., propranolol).
The retrieved literature consistently supports the claim that hemangiomas are treatable with medication. Multiple papers (such as studies 2, 3, 5, 6, 9, and 11) specifically detail the successful use of pharmacological agents like propranolol and other beta-blockers to treat various types of hemangiomas, leading to lesion regression and symptom resolution. There are no papers contradicting the general premise that medication is an effective treatment.
