Please do not believe what you have heard. Mammograms are the best way to screen for breast cancer--they are scientifically proven to save lives. Mammograms give off very little radiation and the benefits FAR outweigh the risks of the test (You get more radiation flying in an airplane across the country).
What you need is a diagnostic mammogram and an ultrasound. MRI is very sensitive, but is reserved for special cases (like screening for high risk women or to determine how extensive cancer is in a patient who has been newly diagnosed with cancer.) One should never get an MRI without a mammogram first--the tests complement one another, but MRI is not perfect and does not replace the mammogram.
