From 06/2006 thru 07/2007 I had 4 mammograms and all reports says that I have grouped microcalcifications on the L outer breast. On 10/2007, I felt a lump on the outer side of my L breast and it has a constant throbbing pain that extend to my underam. My doc. recommended chest x-ray then ultrasound which both found nothing. my doc & I feel the lump but is not seen on any of this exams. MRI was recommended by my doc but on the day of the exam, the radiologist sent me home without doing the MRI, he said it wont do any good so he recommended to my primary physician that I see a breast specialist/gen surgeon. My appt. will be on next week. Did anybody out there have the same symptom as me? You think this is cancer?
