Bladder cancer is a disease in which malignant (cancer) cells
form in the tissues of the bladder.
The bladder is a hollow organ in the lower part of the abdomen. It is shaped like a small balloon and has a muscular wall that
allows it to get larger or smaller. The bladder stores urine until it is passed out of the body. Urine is the liquid waste that is made by
the kidneys when they clean the blood. The urine passes from the two kidneys
into the bladder through two tubes called ureters. When the bladder is emptied
during urination, the urine goes from the bladder to the outside of the body
through another tube called the urethra.
There are three types of bladder cancer that begin in cells in the lining of the
bladder. These cancers are named for the
type of cells that become malignant (cancerous):
Cancer that is confined to the lining of the bladder is called superficial bladder cancer. Cancer that begins in the transitional cells may spread
through the lining of the bladder and invade the muscle wall of the bladder or spread to nearby organs and lymph nodes;
this is called invasive bladder cancer.
See the following PDQ summaries for more information:
Smoking, gender, and diet can affect the risk of developing bladder cancer.
Anything that increases your chance of getting a disease is called a risk factor. Risk factors for bladder cancer include the following:
- Smoking.
- Being exposed to certain substances at work, such as rubber, certain dyes and textiles, paint, and hairdressing supplies.
- A diet high in fried meats and fat.
- Being older, male, or white.
- Having an infection caused by a certain parasite.
Possible signs of bladder cancer include blood in the urine or
pain during urination.
These and other symptoms may be caused by bladder cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems
occur:
- Blood in the urine (slightly rusty to bright red in
color).
- Frequent urination, or feeling the need to urinate without
being able to do so.
- Pain during urination.
- Lower back pain.
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, taken 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 prognosis (chance of recovery) depends on the following:
- 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.

After bladder cancer has been diagnosed, tests are done
to find out if cancer cells have spread within the bladder or to other parts of
the body.
The process used to find out if cancer has spread within the bladder lining and muscle or to other parts of the body is called staging. The information gathered from the
staging process determines the stage of the disease. It is important to know
the stage in order to plan treatment. The following tests and
procedures may be used in the staging process:
- 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.
- CT scan (CAT scan):
A procedure that makes a series of detailed pictures of areas inside the body, taken 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.
- MRI (magnetic
resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
- Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
- Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
- Bone scan: A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner.
There are three ways that cancer spreads in the body.
The three ways that cancer spreads in the body are:
- Through tissue. Cancer invades the surrounding normal tissue.
- Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
- Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.
When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, if breast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
The following stages are used for bladder cancer:
Stage 0 (Papillary Carcinoma and Carcinoma in Situ)
In stage 0, abnormal cells are found in tissue lining the
inside of the bladder. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is divided into stage 0a and stage 0is, depending on the type of the tumor:
Stage I
In stage I, cancer has formed and spread to the layer of tissue under the inner lining of the bladder.
Stage II
In stage II, cancer has spread to either the inner half or outer half of the muscle wall of the bladder.
Stage III
In stage III, cancer has spread from the bladder to the fatty layer of tissue surrounding it, and may
have spread to the reproductive organs (prostate, uterus, vagina).
Stage IV
In stage IV, cancer has spread from the bladder to the wall of the abdomen or pelvis. Cancer may have spread to one or more lymph nodes or to
other parts of the body.
Back to Top Recurrent Bladder Cancer
Recurrent bladder cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the bladder or in other parts of the body.

There are different types of treatment for patients with bladder
cancer.
Different types of treatment are available for patients with bladder cancer. Some treatments are standard (the currently used treatment), and some
are being tested in clinical trials.
A treatment clinical trial is a research study meant to help
improve current treatments or obtain information on new treatments for patients
with cancer. When clinical trials show that a new treatment is better than the
standard treatment, the new
treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Four types of standard treatment are used:
Surgery
One of the following types of surgery may be done:
- Transurethral resection (TUR) with fulguration: Surgery in which a cystoscope (a thin lighted tube) is inserted into the bladder through the urethra.
A tool with a small wire loop on the end is then used to remove the
cancer or to burn the tumor away with high-energy electricity. This is known as fulguration.
- Radical cystectomy: Surgery to remove the bladder and any lymph nodes and nearby organs that contain cancer. This surgery may be
done when the bladder cancer invades the muscle wall, or when superficial cancer involves a large part of the bladder. In men, the nearby organs that are
removed are the prostate and the seminal vesicles. In women, the uterus, the ovaries, and part of the vagina are removed. Sometimes, when the cancer has
spread outside the bladder and cannot be completely removed, surgery to remove
only the bladder may be done to reduce urinary symptoms caused by the cancer.
When the bladder must be removed, the surgeon creates another way for urine to
leave the body.
- Segmental cystectomy: Surgery to remove part of the
bladder. This surgery may be done for patients who have a low-grade tumor that
has invaded the wall of the bladder but is limited to one area of the bladder.
Because only a part of the bladder is removed, patients are able to urinate normally after
recovering from this surgery.
- Urinary diversion: Surgery to make a new way for
the body to store and pass urine.
Even if the doctor removes all the cancer that can be seen at the
time of the surgery, some patients may be given chemotherapy after surgery to
kill any cancer cells that are left. Treatment given after surgery, to increase
the chances of a cure, is called adjuvant therapy.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the spinal column, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Bladder cancer may be treated with intravesical (into the bladder through a tube inserted into the urethra) chemotherapy. The way the chemotherapy is given depends on the type and stage of the cancer being treated.
Biologic therapy
Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in
clinical trials. It may not mention every new treatment being studied.
Information about clinical trials is available from the
NCI Web site.
Chemoprevention
Chemoprevention is the use of drugs, vitamins, or other substances to reduce the risk of developing cancer or to reduce the risk that cancer will recur (come back).
Photodynamic therapy
Photodynamic therapy (PDT) is a cancer treatment that uses a drug and a certain type of laser light to kill cancer cells. A drug that is not active until it is exposed to light is injected into a vein. The drug collects more in cancer cells than in normal cells. Fiberoptic tubes are then used to carry the laser light to the cancer cells, where the drug becomes active and kills the cells. Photodynamic therapy causes little damage to healthy tissue.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's clinical trials database.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. This is sometimes called re-staging.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

Back to Top About PDQ
PDQ is a comprehensive cancer database available on NCI's Web site.
PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.
PDQ contains cancer information summaries.
The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.
The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.
Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.
PDQ also contains information on clinical trials.
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Listings of clinical trials are included in PDQ and are available online at NCI's Web site. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237); TTY at 1-800-332-8615.
