What is a hermangioma?

Hemangioma is a common, non-cancerous tumor that occurs when blood vessels grow abnormally. Hemangiomas can occur in any part of the body, but are most common on the skin and in the liver.

Hemangiomas can vary in size from small, red spots to large, raised masses. They can be either solid or filled with blood. In most cases, hemangiomas are not painful, but they can sometimes bleed or cause pain if they are located in an area that is subject to a lot of pressure.

Hemangiomas are usually present at birth or appear in early childhood. They often grow rapidly during the first few months of life, but then gradually slow down and may eventually disappear. In most cases, hemangiomas do not require treatment, but they may be removed surgically if they are causing problems.

The exact cause of hemangiomas is not known, but it is thought that they are caused by a combination of genetic and environmental factors. Hemangiomas are more common in premature infants and in children with certain medical conditions, such as Down syndrome.
