While I think this is a great step forward, How can this be described as highly accurate when it missed identifying cancer in 48.5% of the people?

- doctoring 5y agoCancer radiologist here! I don't know about "highly accurate", but certainly pretty fucking good. Because for most of those cancers for most populations, the asymptomatic detection rate is much, much lower. Like close to 0%. There is no general population screening test for, say, pancreatic cancer or ovarian cancer etc.
