Large Core Needle Biopsy of the Breast
What Is It?
A biopsy is a tissue sample removed from the body and examined under a microscope. In a breast biopsy, a doctor removes tissue from a suspicious area so that a pathologist can determine whether the tissue contains cancerous cells.
At one time, surgeons only performed biopsies by making an incision in the breast and removing the suspicious tissue along with some normal tissue from around it. These surgical biopsies leave scars and may change the size and shape of the breast.
Today, doctors can often use newer techniques. These include fine needle aspiration and core needle biopsy, which don't leave scars or change the shape of the breast. This is a significant advantage, because four out of five women who have biopsies do not have cancer.
