Which cancer type is defined as a malignant tumor of connective and supporting tissues such as bone, muscle, fat, cartilage, and blood vessels?

• A. Carcinoma
• B. Leukemia
• C. Adenocarcinoma
• D. Sarcoma

Answer: (D)

This item focuses on how cancers are classified by the tissue they originate from. A malignant tumor of connective and supporting tissues—such as bone, muscle, fat, cartilage, and blood vessels—is called a sarcoma. That’s because sarcomas arise from mesenchymal (connective) tissues, which form the supporting framework of the body. In contrast, carcinomas develop from epithelial cells that line organs and skin, with adenocarcinoma being a common glandular subtype of carcinoma. Leukemia is a cancer of blood-forming cells in the bone marrow and blood, not a solid tumor arising from connective tissue. So the description fits sarcoma best.
