Tissue sampling

A biopsy is the removal of a small piece of tissue for lab examination.

Core needle biopsy of the breast

A core needle biopsy of the breast is a procedure to remove samples of tissue from a lump or suspicious area of the breast and evaluate it for breast cancer. Core needle biopsy uses a long, hollow needle to take several core samples of tissue, usually using ultrasound or mammographic guidance. The samples are then sent to a lab for analysis.
