A biopsy is the removal of tissue in order to examine it for disease. The tissue samples can be taken from any part of the body. Biopsies are performed in several different ways. Some biopsies involve removing a small amount of tissue with a needle while others involve surgically removing an entire lump, or nodule, that is suspicious.

Often, the tissue is removed by placing a needle through the skin to the area of abnormality. Biopsies can be safely performed with imaging guidance such as ultrasound, X-ray, computed tomography (CT), or magnetic resonance imaging (MRI). These types of imaging are used to determine exactly where to place the needle and perform the biopsy.

Frequently Asked Questions

 Why are biopsies performed? When a nodule is detected, imaging tests may be performed to help determine if it is benign (non-cancerous) or malignant (cancerous). If imaging studies cannot clearly define the abnormality, a biopsy may be necessary.
 What body parts are usually biopsied? Biopsies are performed in many areas of the body and for many reasons. The following is a list of common biopsy types: Bone; Breast; Kidneys; Liver; Lung; Thyroid; and Prostate.
 How long does the procedure take? The procedure is usually completed within one hour. You may be required to stay in an area for observation for several hours after the biopsy, depending on the type of biopsy performed.
