Biopsy
A Biopsy is a procedure to remove a piece of tissue or a sample of cells from your body so that it can be analyzed in a laboratory. If you're 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 some other condition.
Biopsy is a medical test commonly performed by a surgeon, or interventional radiologist involving extraction of sample cells or tissues for examination to determine the presence or extent of a disease. The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy. An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration biopsy.
