Worried for my mother

Hello, I have been reading but I wanted to post my situation. I am worried about my mother. Here is the situation.

In early December she was complaining about breast pain at about the 3 o'clock region. She went to her Dr and had a mammogram which came back clear.

Fast forward to early February she calls me and says she felt a palpable lump at about the 12 o'clock region that is about the size of a pea. A little bit bigger than the bb sized one she had under her breast. She gets to her Dr and he orders an ultrasound.

Ultrasound results come back and they called to tell her that there was an area of concern and the artifacts so the Dr wanted to do a biopsy. So next Wednesday she does that.

Is there anything positive you can help me with here. I appreciate reading all your answers.
