Cancer Biopsy

During a biopsy, a doctor removes a sample of tissue or fluid from the body. A pathologist inspects the cells under a microscope to see if they are cancerous. If the cells are found to be cancerous, a biopsy may help determine whether the cancer began at the site of the biopsy or if it started somewhere else in the body and spread to the biopsy site. Some biopsies are performed endoscopically, others under image guidance, such as ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) in the radiology suite. In some cases, biopsies are performed in the operating suite. This allows your doctor to collect tissue from deep inside the body.
