breast lesion

I had hysterectomy and left-oopherectomy in Jun 2007 due to dermoid cysts on left ovary and multi-fibroids in uterus. I am doing mammography and breast ultrasound annually. This year, the ultra sound captures a lesion measuring 4 mm in the lower quadrant of the left breast. It has a regular oval shaped but dark grey in color. Mammography didn’t capture anything. I have numerous cysts in both breasts which are densed, they all have regular oval shaped and black. Is it possible that I have abnormal solid nodule? Is it hyper-echoic lesion? I hope you can help.
Thank you

The questions you ask would be answered by the reports by the Radiologist who read your films. Hyper and Hypo echoic simply means that the lesion reflects more or less waves than would be expected. Any nodule can be "abnormal" ... in fact NO lesion is "normal". If there is considerable doubt as to the exact cause or nature of this lesion then a biopsy most likely be advised. Regards .....
