To the Editor: Dr Welch and colleagues1 argue that, because of lead time bias, men diagnosed
with prostate cancer might not be living longer and instead are only being
diagnosed earlier. Increasing 5-year survival rates thus may not reflect reduced
disease burden and should not be taken as evidence of improved prevention,
screening, or therapy.
