I was told I had to have a biopsy after two mammograms found a 10 mm lesion in my left breast.  I went to the breast surgeon yesterday.  She did a breast exam and couldn't feel anything and said that to come back in 6 months and get another mammogram.  As if that wasn't enough, about 30 minutes later at Applebee's, I met a woman who had the exact same situation I did. 2 bad mammograms, ultrasound didn't show anything, deep location of lesion, and SAME dr. couldn't feel anything on her.  She did do a wire biopsy on her.  I have huge breast and am not surprised she couldn't feel anything on me.  My left breast constantly has a dull feeling and sometimes shoots a burning pain through there.  I need some advice on what I should do.  The dr. says she thinks its superimposed breast tissues.  I don't know how she can tell for sure.  Please someone tell me what they think!!!  I had cervical cancer 7 years ago too.
