What is sarcoma?

Sarcoma is a rare type of cancer that begins in the connective tissues of the body. Connective tissues are parts of the body that join together, support or separate other tissues or organs. Examples are bones, cartilage, fat, muscles, membranes, tendons and ligaments. Sarcoma occurs when abnormal cells in these types of tissue grow in an uncontrolled way. 

Sarcomas can develop anywhere in the body. 

Sarcomas are rare across all age groups, but they are one of the most common types of cancer in children.
