Biopsy for bladder cancer

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. If the cells are found to be cancerous, a biopsy can 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 under image guidance, such as ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI). This allows your doctor to collect cells from deeper inside the body. Depending on the type of biopsy performed, you will receive an anesthetic to minimize any pain.

Biopsy for bladder cancer

With bladder cancer, biopsies are usually done during a cytoscopy. A thin instrument is inserted through the cytoscopy tube, and a small sample of tissue that appears possibly cancerous is collected from inside the bladder.
