Show Hint
Memorizing common medical prefixes is key for biology exams.
\textbf{Carcino-} = Cancer (from epithelial cells)
\textbf{Sarco-} = Flesh (connective/mesenchymal tissue)
\textbf{Chondro-} = Cartilage
\textbf{Myelo-} = Marrow/Spinal cord
\textbf{Hema-} = Blood
\end{itemize}
These prefixes can help you quickly deduce the origin of many cancer types.
Step 1: Concept Overview:
This question tests knowledge of cancer terminology, specifically tumor classification by tissue origin. "-oma" denotes a tumor, while the prefix indicates the tissue type.
Step 2: Detailed Explanation:
Matching cancer types (LIST-I) to their tissues of origin (LIST-II):
- A. Carcinoma: Malignant tumors from epithelial cells lining organ surfaces. Thus, Carcinoma \(\rightarrow\) Epithelial Tissue. (A \(\rightarrow\) IV).
- B. Chondroma: "Chondro-" signifies cartilage. A chondroma is a benign cartilage tumor. Thus, Chondroma \(\rightarrow\) Cartilage. (B \(\rightarrow\) II).
- C. Sarcoma: Malignant tumors from mesenchymal tissues (connective tissues like bone, fat, muscle). Thus, Sarcoma \(\rightarrow\) Muscle. (C \(\rightarrow\) I).
- D. Myeloma: "Myelo-" signifies bone marrow. Myeloma (multiple myeloma) is plasma cell cancer (white blood cells in bone marrow). Thus, Myeloma \(\rightarrow\) Blood. (D \(\rightarrow\) III).
Step 3: Solution:
The correct pairings are: A-IV, B-II, C-I, D-III, corresponding to option (A).
