A full-body MRI screening for cancer, when performed on asymptomatic individuals, yields a net benefit of approximately 0.025 Quality-Adjusted Life Years (QALYs) per person. This benefit is equivalent to approximately 926 micromorts, a risk level comparable to activities such as a year of smoking, two BASE jumps, or a day on the front lines in Ukraine. The author expresses skepticism about the utility of such tests on healthy individuals, emphasizing the importance of base rates in medical diagnostics and questioning the practical value of QALYs without a relatable context.
