A sarcoma is a rare type of malignant tumor
that grows on the connecting tissue found between the body's organs, and rapidly multiplies throughout the body. These tumors are unique in containing only partially developed cells
. They can also be found developing on muscles and bones, respectively referred to as myosarcoma and osteosarcoma. Depending on which cells are predominantly found in these tumors, they can be categorized as chondrosarcoma, derived from cartilage cells; and angiosarcoma, from blood vessels; among others.
