Breast biopsy
Breast Biopsy
A Breast Biopsy (/ˈbraɪ.ɒp.si/) is a medical procedure that involves the removal of cells or tissues from the breast to examine under a microscope. The procedure is often performed to investigate suspicious breast lumps or abnormalities detected by physical exam, mammography, or other imaging studies.
Etymology
The term "biopsy" is derived from the Greek words "bios" (life) and "opsis" (sight), meaning "to view life." The term "breast" comes from the Old English "breost," which means "chest."
Types of Breast Biopsy
There are several types of breast biopsies, including:
- Fine-needle aspiration biopsy (FNAB): A thin needle is used to remove a sample of cells from the breast.
- Core needle biopsy (CNB): A larger needle is used to remove a sample of breast tissue.
- Vacuum-assisted biopsy (VAB): A vacuum-powered instrument is used to collect multiple tissue samples during one needle insertion.
- Surgical biopsy: A surgical procedure is used to remove all or part of a lump or suspicious area. It can be either an incisional biopsy (removal of part of the lump) or an excisional biopsy (removal of the entire lump).
Procedure
The procedure for a breast biopsy can vary depending on the type of biopsy being performed. However, in general, the area is numbed with a local anesthetic, and a needle or surgical instrument is inserted into the suspicious area to remove tissue or cells. The samples are then sent to a pathology lab for analysis.
Risks and Complications
Like any medical procedure, a breast biopsy carries some risks. These may include infection, bleeding, bruising, and changes in the breast's appearance. There may also be a risk of false-negative results, which means the test could miss a cancer diagnosis.
