Overview
Soft tissue sarcomas are relatively uncommon cancers. They account for less than 1 % of all new cancer cases each year.
Epidemiology
In 2006, about 9,500 new cases were diagnosed in the United States.[1]
Age
Soft tissue sarcomas are more commonly found in older patients (>50 years old) although in children and adolescents under age 20, certain histologies are common (rhabdomyosarcoma).
