What are benign hemangiomas?

Benign growth: Its a growth thats not cancerous. It's made up of cells from blood vessels.

Benign: Hemangiomas are collections of vascular tissue in an unexpected location, and of low vascular flow. They are benign (not cancer), and usually painless and asymptomatic. Therefore, they are generally not treated. They are particularly common in the liver, skin, and spine. Having said that, very large hemangiomas can bleed, fracture if in the spine, cause pain, or be disfiguring and may be treated.
