Text 1: Public-health official Park argues that mass screening for early cancers saves lives. Programs like mammography for breast cancer and colonoscopy for colon cancer detect tumors at treatable stages, before symptoms develop; population-wide screening, Park contends, has reduced mortality from these diseases.
Text 2: Public-health official Singh accepts mortality reductions in some screening programs but argues that the case is uneven across cancers. Some screening — for example, prostate-specific antigen testing — has detected indolent tumors that would never have harmed patients while subjecting many to needless treatment. "Screening saves lives" generalizes across very different evidence bases.
Based on the texts, how would Singh (Text 2) most likely respond to Park's claim?
- Acheck_circle
He would accept some benefits while arguing that the case differs sharply across cancers.
- B
He would say all cancer screening should be expanded immediately.
- C
He would deny that any screening reduces mortality.
- D
He would propose that no early detection is ever useful.
Explanation
Singh accepts some benefits but argues for case-by-case evaluation. B captures this position.
