Bladder Cancer Diagnosis
Tests that examine the urine, vagina, or rectum are used to help detect (find) and diagnose bladder cancer.
The following tests and procedures may be used:
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body from different angles. The pictures are made by a computer linked to an X-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
- Urinalysis: A test to check the color of urine and its contents, such as sugar, protein, red blood cells, and white blood cells.
- Internal exam: An exam of the vagina and/or rectum. The doctor inserts gloved fingers into the vagina and/or rectum to feel for lumps.
- Intravenous pyelogram (IVP): A series of X-rays of the kidneys, ureters and bladder to find out if cancer is present in these organs. A contrast dye is injected into a vein. As the contrast dye moves through the kidneys, ureters, and bladder, X-rays are taken to see if there are any blockages.
- Cystoscopy: A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.
- Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. A biopsy for bladder cancer is usually done during cystoscopy. It may be possible to remove the entire tumor during biopsy.
- Urine cytology: Examination of urine under a microscope to check for abnormal cells.
Certain factors affect prognosis (chance of recovery) and treatment options:
- The stage of the cancer (whether it is superficial or invasive bladder cancer, and whether it has spread to other places in the body). Bladder cancer in the early stages can often be cured.
- The type of bladder cancer cells and how they look under a microscope.
- The patient’s age and general health.
Treatment options depend on the stage of bladder cancer.
