The date of diagnosis is often confirmed __ before a biopsy or surgical resection is performed.

• A. Clinically
• B. Radiographically
• C. Pathologically
• D. Laboratory tests

Answer: (A)

Clinical assessment is what often first establishes a cancer diagnosis in practice. When a patient’s history, physical examination, and imaging create a consistent picture of malignancy, clinicians record a working diagnosis and begin planning the diagnostic workup, including a biopsy or surgical procedure. This clinical identification allows earlier treatment decisions and scheduling while the definitive confirmation comes from tissue analysis after biopsy or resection. Imaging and laboratory tests can raise suspicion or support findings but cannot by themselves prove malignancy; pathology after tissue examination remains the gold standard for confirming the diagnosis.
