Percutaneous image-guided core breast biopsy.

Percutaneous image-guided core biopsy is an accurate, fast, minimally invasive, and less expensive alternative to surgery for the diagnosis of breast lesions. Percutaneous core biopsy is usually performed under stereotactic or ultrasound guidance, using an automated needle or vacuum-assisted biopsy probe. Use of percutaneous core biopsy spares the need for surgery in most women with benign disease and expedites treatment in women with breast cancer.
