Sarcoma Stocks List

Sarcoma

A sarcoma is a cancer that arises from transformed cells of mesenchymal (connective tissue) origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma. Human sarcomas are quite rare. Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma. The term is from the Greek σάρξ sarx meaning "flesh".
