Chondrosarcoma is broadly cancer, but in medical terms, we wouldn’t necessarily phrase it that way; we simply describe chondrosarcoma as a type of malignant tumor, and currently, its treatment outcomes are not very good. Generally, when we talk about cancer, we’re referring to malignant tumors that originate from epithelial tissue, including cancers like stomach cancer, lung cancer, colon cancer, and liver cancer, which all derive from epithelial tissues. However, because chondrosarcoma originates from mesenchymal tissue, which includes muscle, cartilage, blood vessels, and nerves, malignant tumors that occur in these areas are usually called sarcomas. Sarcomas are definitely malignant, but to strictly call them cancer is not particularly precise.
