Haemangioma is a benign (non-cancerous) tumour made up of blood vessels. They can occur anywhere on the body. They can vary in size and appearance, and can be classified as either superficial (just under the skin) or deep (involving deeper layers of tissue). Some haemangiomas may disappear on their own over time, while others may require treatment if symptomatic.
They do not need removing unless there is a history of sudden change such as increasing in size quickly or becoming painful.
