Hemangiomas are benign tumors made up of blood vessels, often appearing as red or purple marks on the skin. They are most commonly found in infants and usually develop within the first few weeks of life. While they can grow rapidly, many hemangiomas shrink and fade over time without treatment. These growths can occur anywhere on the body but are frequently seen on the face, scalp, and back. In most cases, hemangiomas do not cause any pain or complications. However, if they interfere with vision or breathing, medical intervention may be necessary to manage the condition.
