Endoscopic biopsy

During endoscopy, your doctor uses a thin, flexible tube (endoscope) with a light on the end to see structures inside your body. Special tools are passed through the tube to take a small sample of tissue to be analyzed.

What type of endoscopic biopsy you undergo depends on where the suspicious area is located. Tubes used in an endoscopic biopsy can be inserted through your mouth, rectum, urinary tract or a small incision in your skin.

Examples of endoscopic biopsy procedures include cystoscopy to collect tissue from inside your bladder, bronchoscopy to get tissue from inside your lung and colonoscopy to collect tissue from inside your colon.

Depending on the type of endoscopic biopsy you undergo, you may receive a sedative or anesthetic before the procedure.
