Interesting: The cumulative risk of a false positive mammogram result after 10 mammos: 49%

Posted by James Bond (aka Igor) (aka Igor) Dec 4 '09, 13:14

The risk of a biopsy as a result of a false positive mammo: 19%

400 40 year olds will have false positive mammograms resulting in 100 biopsies to find a single woman with cancer

And did we know that Breast Self Exams are no longer recommended.

For the source junkies:

- There have been 3 major studies done (in Canda, China, and Australia). Women were followed for 10 years. Results showed no gain, but harm. - James Bond (aka Igor) Dec 4, 13:24 1

Just how many unnecessary biopsies are worth saving one woman's life? Is it closer to 50? -- nm - Agent.Vermin Dec 4, 13:18
I'd rather have a false positive than a false negative. -- nm - loosilu Dec 4, 13:16 1
