Definition
A breast biopsy is the removal of breast tissue for examination by a pathologist. This can be accomplished surgically or by extracting, or withdrawing, tissue through a needle.A biopsy is recommended when a significant abnormality is found by physical examination or an imaging test. Examples of an abnormality can include a breast
During a needle biopsy on the breast, a local anesthetic is used, and a needle with a looped end is inserted into the potential tumor (A). A sample is taken (B), and the needle withdrawn (C). The sample is sent to a laboratory for analysis. (Illustration by GGS Inc.)
lump felt during physical self-examination or tissue changes noticed from a mammogram test. Before a biopsy is performed, it is important to make sure that the threat of cancer cannot be ruled out by a simpler, less invasive examination. A lump may be obviously harmless when examined by ultrasound. If less invasive tests are not conclusive, the presence of cancer or a variety of benign breast conditions can be determined by using a biopsy.Surgical biopsy
There are two major types of surgical breast biopsy: excisional and incisional. An excisional biopsy is a surgical procedure where the entire area of concern and some surrounding tissue is removed. It is usually done as an outpatient procedure in a hospital or freestanding surgery center. The patient may be awake and is sometimes given medication to make her drowsy. The area to be operated on is numbed with local anesthetic. Infrequently, general anesthesia is used. An excisional biopsy itself usually takes under one hour to perform. The total amount of time spent at the facility depends on the type of anesthesia used, whether a needle localization was done, and the extent of the surgery.If a mass is very large, an incisional biopsy may be performed. In this case, only a portion of the area is removed and sent for analysis. The procedure is the same as an excisional biopsy in other respects.
Aftercare
After a surgical biopsy, the incision will be closed with stitches and covered with a bandage. The bandage can usually be removed in one or two days. Stitches are taken out approximately one week afterward. Depending on the extent of the operation, normal activities can be resumed in approximately one to three days. Vigorous exercise may be limited for one to three weeks.
The skin opening for a needle biopsy is minimal. It may be closed with thin, clear tape (called a steri-strip) or covered with a small bandage. The patient can return to her usual routine immediately after the biopsy. Strenuous activity or heavy lifting is not recommended for 24 hours. Any bandages can be removed one or two days after the biopsy.
