Urethral cancer is a disease in which malignant (cancer) cells form in the tissues of the urethra.
\n
There are different types of urethral cancer that begin in cells that line the urethra.
\n
A history of bladder cancer can affect the risk of urethral cancer.
\n
Signs of urethral cancer include bleeding or trouble with urination.
\n
Tests that examine the urethra and bladder are used to diagnose urethral cancer.
\n
Certain factors affect prognosis (chance of recovery) and treatment options.

Urethral cancer is a disease in which malignant (cancer) cells form in the tissues of the urethra.
\n
The urethra is the tube that carries urine from the bladder to outside the body. In women, the urethra is about 1\u00bd inches long and is just above the vagina. In men, the urethra is about 8 inches long, and goes through the prostategland and the penis to the outside of the body. In men, the urethra also carries semen.

The inside of the left kidney shows the renal pelvis. An inset shows the renal tubules and urine. Also shown are the prostate and penis (left panel) and the uterus (right panel). Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra. \n \n \n
Squamous cell carcinoma is the most common type of urethral cancer. It forms in the thin, flat cells in the part of the urethra near the bladder in women, and in the lining of the urethra in the penis in men.
\n
Transitional cell carcinoma forms in the area near the urethral opening in women, and in the part of the urethra that goes through the prostate gland in men.
\n
Adenocarcinoma forms in the glands that are around the urethra in both men and women.
A history of bladder cancer can affect the risk of urethral cancer.
\n
Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn\u2019t mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for urethral cancer include the following:
Signs of urethral cancer include bleeding or trouble with urination.
\n
These and other signs and symptoms may be caused by urethral cancer or by other conditions. There may be no signs or symptoms in the early stages. Check with your doctor if you have any of the following:
\n
\n
\n
Trouble starting the flow of urine.
\n
Weak or interrupted (\"stop-and-go\") flow of urine.
Tests that examine the urethra and bladder are used to diagnose urethral cancer.
\n
The following tests and procedures may be used:
\n
\n
\n
Physical exam and health 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.
\n
Pelvic exam: An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas. \n \n Enlarge \n \n \n Pelvic exam. A doctor or nurse inserts one or two lubricated, gloved fingers of one hand into the vagina and presses on the lower abdomen with the other hand. This is done to feel the size, shape, and position of the uterus and ovaries. The vagina, cervix, fallopian tubes, and rectum are also checked. \n \n
\n
Digital rectal exam: An exam of the rectum. The doctor or nurse inserts a lubricated, gloved finger into the lower part of the rectum to feel for lumps or anything else that seems unusual.
Urinalysis: A test to check the color of urine and its contents, such as sugar, protein, blood, and white blood cells. If white blood cells (a sign of infection) are found, a urine culture is usually done to find out what type of infection it is.
\n
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
\n
Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following: \n
The portion of the blood sample made up of red blood cells.
\n
\n
\n
CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the pelvis and abdomen, 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.
\n
Ureteroscopy: A procedure to look inside the ureter and renal pelvis to check for abnormal areas. A ureteroscope is a thin, tube-like instrument with a light and a lens for viewing. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. A tool may be inserted through the ureteroscope to take tissue samples to be checked under a microscope for signs of disease. \n \n Enlarge \n \n \n A ureteroscopy is a procedure that uses a ureteroscope (a thin, tube-like instrument with a light and a lens for viewing) to look inside the ureter and renal pelvis to check for abnormal areas. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. \n \n
\n
Biopsy: The removal of cell or tissue samples from the urethra, bladder, and, sometimes, the prostate gland. The samples are viewed under a microscope by a pathologist to check for signs of cancer.
\n
\n
\n \n \n
Certain factors affect prognosis (chance of recovery) and treatment options.
\n
The prognosis and treatment options depend on the following:
\n
\n
\n
Where the cancer formed in the urethra.
\n
Whether the cancer has spread through the mucosa lining the urethra to nearby tissue, to lymph nodes, or to other parts of the body.
\n
Whether the patient is a male or female.
\n
The patient's general health.
\n
Whether the cancer has just been diagnosed or has recurred (come back).

Stages of Urethral Cancer
\n
\n
\n
\n
Key Points
\n
\n
\n
After urethral cancer has been diagnosed, tests are done to find out if cancer cells have spread within the urethra or to other parts of the body.
\n
There are three ways that cancer spreads in the body.
\n
Cancer may spread from where it began to other parts of the body.
\n
Urethral cancer is staged and treated based on the part of the urethra that is affected. \n
\n
Distal urethral cancer
\n
Proximal urethral cancer
\n
\n
Bladder and/or prostate cancer may occur at the same time as urethral cancer.
\n
Urethral cancer can recur (come back) after it has been treated.
\n
\n
\n
\n \n
After urethral cancer has been diagnosed, tests are done to find out if cancer cells have spread within the urethra or to other parts of the body.
\n
The process used to find out if cancer has spread within the urethra 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.
\n
The following procedures may be used in the staging process:
\n
\n
\n
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.
\n
CT scan (CAT scan) of the pelvis and abdomen: A procedure that makes a series of detailed pictures of the pelvis and abdomen, 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.
\n
MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of the urethra, nearby lymph nodes, and other soft tissue and bones in the pelvis. A substance called gadolinium is injected into the patient through a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
\n
Urethrography: A series of x-rays of the urethra. 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. A dye is injected through the urethra into the bladder. The dye coats the bladder and urethra and x-rays are taken to see if the urethra is blocked and if cancer has spread to nearby tissue.
\n
\n
\n \n \n
There are three ways that cancer spreads in the body.
Tissue. The cancer spreads from where it began by growing into nearby areas.
\n
Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
\n
Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
\n
\n
\n \n \n
Cancer may spread from where it began to other parts of the body.
\n
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.
\n
\n
\n
Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
\n
Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.
\n
\n
\n
The metastatic tumor is the same type of cancer as the primary tumor. For example, if urethral cancer spreads to the lung, the cancer cells in the lung are actually urethral cancer cells. The disease is metastatic urethral cancer, not lung cancer.
\n
\n \n
\n \n
\n \n Many cancer deaths are caused when cancer moves from the original tumor and spreads to other tissues and organs. This is called metastatic cancer. This animation shows how cancer cells travel from the place in the body where they first formed to other parts of the body. \n \n \n
\n \n \n
Urethral cancer is staged and treated based on the part of the urethra that is affected.
\n
Urethral cancer is staged and treated based on the part of the urethra that is affected and how deeply the tumor has spread into tissue around the urethra. Urethral cancer can be described as distal or proximal.
\n \n Enlarge \n \n \n Anatomy of the distal and proximal urethra. Urine flows out of the bladder and leaves the body through the urethra. The part of the urethra that is closest to the bladder is called the proximal urethra. The part that is closest to where the urine leaves the body is called the distal urethra. The urethra is about 8 inches long in men and about 1\u00bd inches long in women. \n \n \n \n
Distal urethral cancer
\n
In distal urethral cancer, the cancer usually has not spread deeply into the tissue. In women, the part of the urethra that is closest to the outside of the body (about \u00bd inch) is affected. In men, the part of the urethra that is in the penis is affected.
Bladder and/or prostate cancer may occur at the same time as urethral cancer.
\n
In men, cancer that forms in the proximal urethra (the part of the urethra that passes through the prostate to the bladder) may occur at the same time as cancer of the bladder and/or prostate. Sometimes this occurs at diagnosis and sometimes it occurs later.
\n \n \n
Urethral cancer can recur (come back) after it has been treated.
\n
The cancer may come back in the urethra or in other parts of the body.

\n
Key Points
\n
\n
\n
There are different types of treatment for patients with urethral cancer.
\n
The following types of treatment are used: \n
\n
Surgery
\n
Radiation therapy
\n
Chemotherapy
\n
Active surveillance
\n
\n
New types of treatment are being tested in clinical trials.
\n
Treatment for urethral cancer may cause side effects.
\n
Patients may want to think about taking part in a clinical trial.
\n
Patients can enter clinical trials before, during, or after starting their cancer treatment.
\n
Follow-up tests may be needed.
\n
\n
\n
\n \n
There are different types of treatment for patients with urethral cancer.
\n
Different types of treatments are available for patients with urethral 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.
\n \n \n
The following types of treatment are used:
\n \n
Surgery
\n
Surgery to remove the cancer is the most common treatment for cancer of the urethra. One of the following types of surgery may be done:
Transurethral resection (TUR): Surgery to remove the cancer using a special tool inserted into the urethra.
\n
Electroresection with fulguration: Surgery to remove the cancer by electric current. A lighted tool with a small wire loop on the end is used to remove the cancer or to burn the tumor away with high-energy electricity.
\n
Laser surgery: A surgical procedure that uses a laser beam (a narrow beam of intense light) as a knife to make bloodless cuts in tissue or to remove or destroy tissue.
Partial penectomy: Surgery to remove the part of the penis surrounding the urethra where cancer has spread. Plastic surgery may be done to rebuild the penis.
\n
Radical penectomy: Surgery to remove the entire penis. Plastic surgery may be done to rebuild the penis.
\n
\n
\n
If the urethra is removed, the surgeon will make a new way for the urine to pass from the body. This is called urinary diversion. If the bladder is removed, the surgeon will make a new way for urine to be stored and passed from the body. The surgeon may use part of the small intestine to make a tube that passes urine through an opening (stoma). This is called an ostomy or urostomy. If a patient has an ostomy, a disposable bag to collect urine is worn under clothing. The surgeon may also use part of the small intestine to make a new storage pouch (continent reservoir) inside the body where the urine can collect. A tube (catheter) is then used to drain the urine through a stoma.
\n
After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.
\n \n \n
Radiation therapy
\n
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:
\n
\n
\n
External radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer.
\n
Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. Internal radiation therapy is also called brachytherapy.
\n
\n
\n
The way the radiation therapy is given depends on the type of cancer and where the cancer formed in the urethra. External and internal radiation therapy are used to treat urethral cancer.
\n \n \n
Chemotherapy
\n
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells 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 cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type of cancer and where the cancer formed in the urethra.
\n \n \n
Active surveillance
\n
Active surveillance is following a patient's condition without giving any treatment unless there are changes in test results. It is used to find early signs that the condition is getting worse. In active surveillance, patients are given certain exams and tests, including biopsies, on a regular schedule.
\n \n \n \n
New types of treatment are being tested in clinical trials.
\n
Information about clinical trials is available from the NCI website.
\n \n \n
Treatment for urethral cancer may cause side effects.
Patients may want to think about taking part in a clinical trial.
\n
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.
\n
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.
\n
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.
\n \n \n
Patients can enter clinical trials before, during, or after starting their cancer treatment.
\n
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.
\n
Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI\u2019s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.
\n \n \n
Follow-up tests may be needed.
\n
As you go through treatment, you will have follow-up tests or check-ups. Some tests that were done to diagnose or stage the cancer may be repeated 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.
\n
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).
Surgery to remove the tumor (transurethral resection), electroresection and fulguration, or laser surgery for tumors that have not spread deeply into tissue.

The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.
\n \n \n
Clinical Trial Information
\n
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.
\n
Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
