Chapter 231 Breast Biopsy: Core
DESCRIPTION
Core breast biopsy is a technique used to obtain small tissue samples for the histologic diagnosis of breast masses.
INDICATIONS
Breast mass or suspicious lesion (palpable; nonpalpable masses may be sampled if image guidance is available).
CONTRAINDICATIONS
Local skin infection, known or suspected allergy to agents used (e.g., latex, iodine). Core needle biopsy may not be suitable for patients who have very small or very hard breast lumps; masses close to the chest wall, the nipple, or the surface of the breast; calcifications that require magnification; or very small breasts. Patients who take blood thinners or aspirin should discontinue them in advance of the procedure. Women who cannot remain still or supine for 20 to 40 minutes because of physical illness or other problems are not good candidates for stereotactic core needle biopsy.
