A study to understand more about soft tissue sarcoma

Soft tissue sarcomas are rare cancers that develop from the cells that make up soft tissue such as muscle and fat for example. As soft tissue is present in all parts of the body, sarcomas can grow almost anywhere. 

Sarcomas often appear as a lump or swelling. But most lumps are not cancerous. Researchers wanted to look at the differences between cancerous and non cancerous (benign) lumps in various types of soft tissue.

They hoped to study tissue samples from people with sarcoma, or suspected sarcoma. They planned to look for and examine abnormal molecules in the tissue, such as proteins or genetic material (DNA).
