Needle Biopsy of the Breast

What is a needle biopsy of the breast?

As the only definitive way to confirm if breast tissue is malignant or benign, needle biopsy is safe and minimally invasive. The procedure is used to retrieve a sample from an abnormal breast lesion by obtaining small amounts of breast tissue through a needle. The tissue is then studied by a pathologist to generate a diagnosis.

There are various needle biopsy methods, including ultrasound-guided biopsy (for highly visible lesions on an ultrasound), stereotactic (for more conspicuous lesions), and MR-guided biopsy (guided in real-time by MRI for potential lesions not visible by mammogram or ultrasound).
