A hemangioma is a type of benign tumor made up of blood vessels that typically appears on the skin or internal organs. Some synonyms for hemangioma include vascular birthmark, strawberry mark, cherry angioma, cavernous hemangioma, and capillary hemangioma. Hemangiomas can vary in size, shape, and color, and may cause discomfort or affect the function of nearby organs. Treatment options for hemangiomas may include medication, laser therapy, surgery, or simply monitoring and observation. While hemangiomas are generally considered harmless and may even disappear on their own over time, it's important to consult with a medical professional to determine the best course of action.
