One downside of missing so few cancers is false positive results. These occur when a mammogram finds something that looks like cancer, but turns out to be benign (not cancer). The more mammograms a woman has, the more likely she is to have a false positive result that will require follow-up tests. Studies have shown the chances of having a false positive result after 10 yearly mammograms are about 50 to 60 percent [31-32].
Up to 70,000 American women a year are treated unnecessarily for breast cancer because they were screened with mammograms, according to an analysis in today's New England Journal of Medicine that's likely to reignite a running debate over the value of cancer screening. The study, whose results are already being challenged by other cancer experts, finds that nearly one in three breast cancer patients – or 1.3 million women over the past three decades – have been treated for tumors that, although detectable with mammograms, would never have actually threatened their lives. The study lays bare perhaps the greatest risk of cancer screening, called "overdiagnosis," long acknowledged by doctors and even advocates of mammograms, but unknown to most women who undergo the procedures.
Mammograms use ionizing radiation at a relatively high dose, which can contribute to the mutations that can lead to breast cancer. You can get as much radiation from one mammogram as you would from 1,000 chest X-rays. Mammography also compresses your breasts tightly, which can lead to a dangerous spread of cancerous cells, should they exist. Dr. Samuel Epstein, one of the world's top cancer experts, has stated:

There is just a lot of confusion about mammography right now.
Better safe than sorry but, you should also consider if you have any of the risk factors for breast cancer..

I went to schedule my mammogram and was told by the clueless (more on that later) receptionist that they are now using digital mammography and not to worry if I am called back for another scan because 60% of their patients have false positives on the initial scan.
She went on to tell me that on the second scan my pictures would be read real time by a radiologist who would meet with me before I left and tell me whether I have the big C or not.
My issues: 1) Why such a high rate of false positives? So I did some research... and here is what I found out...ww5.komen.org...

2) I would freak out if I was called back even knowing there is a high false positive rate. Wouldnt it make more sense to do the radiologist assisted mammograms and not employ these fear tactics?
I am seriously thinking of cancelling my appointment. I am not sure I can trust this place even though its false positive rate is consistent with the national average.
I also read this which caused me even greater concern:Unnecessary Cancer Diagnosis

Now I understand that mammograms save lives, but it also appears it can lead to chemo and breast issues that did not require treatment.
What are you thoughts???
