A hemangioma is a non-cancerous growth of blood vessels that appears as a red or purplish mark on the skin. These vascular tumors are most common in infants but can also develop in adults. While some hemangiomas fade naturally, others may persist or grow, requiring hemangioma treatments in Leesburg, FL, to reduce their size and appearance. The exact cause is unknown, but they are believed to result from abnormal blood vessel development before birth. Although usually harmless, hemangiomas can sometimes cause complications, including ulceration, pain, or interference with vision or breathing if they grow in sensitive areas.
