    Overdiagnosed: Making People Sick In The Pursuit of Health

Lisa Schwartz and Steve Woloshin.

    Breast cancer and stroke screening stories that deserve careful attention

    …h epidemiology at the University of Oxford, dismissed the research. He said, “These authors tell us that randomised controlled trials underestimate the effects of mammography, but don’t say why. Nor do they say anything about overdiagnosis, overtreatment, lead time bias, and length biased sampling. Finding a tumour early is necessary but not sufficient for screening to save lives. It might just mean that screen detected cancers have longer to go …

    …use of the test. The harms associated with mammographic screening include false-positive results, false-positive biopsy results, radiation exposure, false-negative results and false reassurance, pain related to the procedure, overdiagnosis (that is, diagnosis of tumors that are of no threat), and overtreatment.

Maybe Not, And Here’s Why”) wrote about mammography in a medical journal: “The question is no longer whether overdiagnosis occurs, but how often it occurs.” He included the following table to explain the tradeoffs of harms and benefits (debits and credits) – and this was for 50-year old women, for whom the evidence of …

    Beware the polyp police

    … most-studied and widely-used screening programs (for breast and prostate cancer, for instance) have faced evidence-based arguments about whether they were doing more harm than good. The main issue has been the possibility of overdiagnosis. In the case of colon cancer, because most of us will have polyps and very few of us will die from them, screening is also liable to result in overdiagnosis and overtreatment. If and when polyps are found, peop…

    “Simple blood test” – cancer breakthrough or nightmare?

    …epidemic.…Most assume there are no downsides to looking for things to be wrong. But the truth is that early diagnosis is a double-edged sword. While it has the potential to help some, it always has a hidden side-effect: overdiagnosis, the detection of abnormalities that are not destined to ever bother people in their lifetime. Becoming a patient unnecessarily has real human costs. There’s the anxiety of being told you are somehow not …
