Drunksunflower,

The people at the breast cancer support site all wanted me to pursue biopses. Many suggested that the best course of action would be to remove it. They all know how dangerous lumps can be. Some people were misdiagnosed at first when the ultrasound and mammograms didn't show anything. Several had normal biopsies, with the cancer only discovered after they removed their lump. It's scary stuff. Anything is possible. It's possible biopsies can miss the cancer.
