If you are willing to pay out-of-pocket, you can get a breast ultrasound for yourself. There are fast MRIs that are only $300.00 in some places. You can get negotiate the price at private MRI offices. I was given a Diagnostic Mammogram, as opposed to a Screening Mammogram, on my remaining left breast 2 years ago. The doctor said my chances of getting cancer in remaining breast were only 3% in the next 7 years, and therefore, I should go back to the lesser sensitive Screening Mammogram, as nothing had been seen for 3 years in my remaining breast. I refused. They found a lump and another area of calcification in my next Diagnostic mammogram. It was so fast growing that I then was given a breast MRI. I was told that they would have found my cancer a FULL YEAR BEFORE, if I had had a breast MRI! But no one would have recommended it under my circumstances. I know of several incidences where people went ahead and paid for their own MRIs for their peace of mind. Several found cancer before it grew any further.
