- Full body MRI screening for cancer yields a net benefit of 0.025 quality-adjusted life years (QALYs) per person.
- This benefit equates to approximately 926 micromorts, comparable to risks like one year of smoking or two base jumps.
- Medical tests are effective primarily when used on symptomatic individuals due to base rate considerations.
- Routine MRI scans involve trade-offs: most people face minimal costs, but some endure unnecessary tests or biopsies.
- Early cancer detection via MRI benefits a small fraction, gaining about 4 QALYs each.
- The QALY-to-micromort conversion suggests one QALY equals roughly 37,000 micromorts, aiding risk-benefit intuition.
