Question

Lung cancer can be detected at an early stage by:

• A. bone marrow test
• B. blood test
• C. MRI scans
• D. Gene sequencing

Hint:

To find a small lump early, you need a "picture" (Imaging) rather than a "chemical test."

Answer 1

The Correct Option is C

Step 1: Concept
Early detection of localized tumors requires high-resolution imaging.

Step 2: Meaning
While biopsy or sequencing confirms the type of cancer, imaging identifies the presence of a mass.

Step 3: Analysis
MRI (Magnetic Resonance Imaging) or specialized CT scans can detect small nodules or abnormalities in lung tissue long before symptoms appear or systemic markers show up in blood tests.

Step 4: Conclusion
Among the given options, imaging via MRI is a recognized method for identifying physical tumor structures at an early stage. Final Answer: (C)
