A sarcoma (from the Greek σάρξ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus malignant tumors made of cancerous 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.
