Types of sarcoma

Soft tissue sarcomas are rare malignant tumours that arise anywhere in the body from soft tissue such as muscles or fat.

Primary bone tumours arise in the bones, and although these tumours are rare the most common types are osteosarcoma, Ewing's sarcoma and chondrosa arcoma

Metastatic bone disease can cause problems by weakening the bone, which can lead to a fracture or break in the bone

Gastrointestinal stromal tumours – or GIST for short - occur in the gastrointestinal (GI) tract or digestive system.
