With Routine Mammograms, Some Breast Cancers May Be Overtreated
Excerpt:The limitless debate over regular mammograms is getting another kick from an analysis that greatly questions whether the test really does exactly what it's supposed to. Dr. H. Gilbert Welch, coauthor of the analysis of mammography's impact, which was just released in The New England Journal of Medicine, tell Shots that the purpose was to "get down to a very basic question.". That is, do annual mammograms amongst women over 40 find early-stage breast cancers that can be dealt with so that they never ever become deadlier late-stage tumors? Over the last trio of decades, diagnoses of early-stage breast cancers rose, largely due to regular mammogram screening. But the incidence of late-stage cancers decreased only somewhat. That leads some to question whether mammograms are really doing exactly what they're supposed to-- catching early cancers prior to they proceed.

- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.

The last three decades have seen a dramatic increase in early-stage, but not late-stage, breast cancers, as mammography has become routine. Some researchers are concerned that women are being treated for cancers that would never turn deadly.
