A biopsy is a procedure used to remove a small piece of tissue or a sample of cells from your body for laboratory analysis. If you are experiencing certain signs and symptoms or if your doctor has identified an area of concern, you may undergo a biopsy to determine whether you have cancer or another medical condition. During the biopsy, a specialized instrument is used to extract the sample, which is then examined under a microscope by a pathologist. This examination helps in diagnosing diseases, assessing the severity of the condition, and planning the appropriate treatment. Biopsies are essential tools in medical diagnostics, providing crucial information that can guide your healthcare provider in making informed decisions about your care. Depending on the location and nature of the tissue being examined, the procedure can be performed using various techniques, such as needle biopsy, endoscopic biopsy, or surgical biopsy.
