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.
