Needle biopsy

Needle biopsy is a medical procedure that involves the extraction of cells or tissues for examination. It is often used to diagnose diseases, particularly cancer. The procedure is performed using a needle to access the suspicious area.

Procedure

The needle biopsy procedure involves the insertion of a needle into a mass or lump to extract a sample of cells or tissue. The sample is then examined under a microscope to determine the presence of disease. The procedure is typically performed under local anesthesia and can be guided using imaging techniques such as ultrasound, CT, or MRI.

Types

There are several types of needle biopsies, including:

• Fine-Needle Aspiration Biopsy (FNAB): This procedure uses a thin, hollow needle to extract cells from a tumor or lump.

• Core Needle Biopsy (CNB): This procedure uses a larger needle to remove a 'core' of tissue from the abnormal area.

• Vacuum-Assisted Biopsy: This procedure uses a vacuum device to remove more tissue through a single needle insertion.

Risks

While needle biopsy is generally safe, it does carry some risks. These may include bleeding, infection, and an inaccurate diagnosis due to the sample size or location.
