Biopsy for stomach cancer

Biopsy for stomach cancer

Our pathologists analyze tissue samples and lymph nodes under a microscope to determine if cancer cells are present.

What is a 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. 

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. Depending on the type of biopsy performed, you may receive an anesthetic to reduce discomfort.

Biopsies provide tissue samples for diagnosis and may help determine whether the cancer began at the site of the biopsy sample, or if it started somewhere else in the body.

Some sites that are commonly biopsied include the breast, skin, bone marrow, GI tract, lung, liver, bladder, colon and lymph nodes. Our doctors determine the appropriate method of biopsy based on several factors, such as the size, shape, location, and characteristics of the abnormality.
