In addition, in most cases a minimally invasive, needle core biopsy should be performed as the first step in the evaluation process rather than surgery.

If the biopsy shows cancer, the clip will be removed during your breast surgery.

Ultrasound, MRI or x-ray and computer imaging are often used to guide the doctor while they take the sample.
