The lack of Iodine in our body has been implicated in the growing rate of Breast Cancer in this country. Don't get an MRI. Be proactive, take care of your breasts.
Let's face it, that machine is expensive, they just need to pay for it. The reason that they are unable to "catch" cancers with mammograms is that 90% of women in the U.S. have fibrocystic breasts(a precursor to cancer)...therefore the mammmograms are hard to read. And if you have cancer? then what? chemo? cut? burn?
I recommend the book "Breast Cancer & Iodine" by David Derry, MD.
