CauseThe cause of bladder cancer is not known. Changes in the genetic material ( DNA ) of bladder cells may play a role. Chemicals in the environment and cigarette smoking also may play a role. And when the lining of the bladder is irritated for a long time, cell changes that lead to cancer may occur. Some things that cause this are radiation treatment, having catheters in place for a long time, or having the parasite that causes schistosomiasis. Bladder cancer is twice as likely to develop in smokers than in nonsmokers. Experts believe that smoking causes about half of bladder cancer in men and more than one-fourth of bladder cancer in women. 1 Exposure to chemicals and other substances at work—including dyes, paints, leather dust, and others—may also cause bladder cancer. SymptomsThe most common symptoms of bladder cancer include:
Symptoms that may indicate more advanced bladder cancer include:
Other symptoms that may develop when bladder cancer has spread include:
The symptoms of bladder cancer may be similar to symptoms of other bladder conditions. What HappensBladder cancer is the rapid, uncontrolled growth of abnormal cells in the bladder. Cancer usually begins in the lining of the bladder. The cancerous cells may grow through the lining into the muscular wall of the bladder. Invasive bladder cancer may spread to lymph nodes , other organs in the pelvis (causing problems with kidney and bowel function), or other organs in the body, such as the liver and lungs. Bladder cancer is classified by stage and grade. The stage is determined by the cancer growth in the bladder wall and how far it has spread to nearby tissues and other organs, such as the lungs, the liver, or the bones. The grade of bladder cancer is determined by how the cancer cells look in comparison with normal bladder cells. Your doctor finds out the stage and grade of your bladder cancer by gathering information from a variety of tests, including blood tests, urine tests, biopsies , bone scans , X-rays , and CT scans . The stage and grade of your cancer are important in selecting the treatment option that is right for you. Bladder cancer is usually curable if it is diagnosed while the cancer is still contained in the bladder, and about 74% of bladder cancers are diagnosed at this early stage. 2 Survival rates decrease as the stage of cancer becomes more advanced, as the cancer cells become more abnormal (grade), and when the cancer involves lymph nodes or other body organs. What Increases Your RiskThe major risk factors for bladder cancer include:
When To Call a DoctorIf you have been diagnosed with bladder cancer , be sure to follow your doctor's instructions about calling when you have problems, new symptoms, or symptoms that get worse. Call your doctor if you:
Watchful WaitingIf you are concerned about your symptoms or you are concerned about your risk for bladder cancer, make an appointment with your doctor. Watchful waiting is not appropriate if you have symptoms that do not go away. Who To SeeHealth professionals who can evaluate your symptoms and your risk for bladder cancer include:
Doctors who can manage your cancer treatment include: To prepare for your appointment, see the topic Making the Most of Your Appointment. Exams and TestsTo find out whether bladder cancer may be the cause of your urinary symptoms, your doctor will evaluate your:
Initial diagnostic tests will include a cystoscopy, a test that allows your doctor to look at your bladder with a thin lighted scope (cystoscope). Small tissue samples ( biopsies ) of any abnormal areas are taken and looked at under a microscope to find out whether cancer cells are present and what the cells look like (grade). Information from the biopsy, cystoscopy, and sometimes other tests is used to find out the size and extent of the cancer (stage). Cancer stage and grade tell the size and shape of cancer cells and whether they have spread to other body areas. Knowing the stage and grade helps you and your doctor make treatment decisions. Other diagnostic tests that may be done include:
If bladder cancer is diagnosed, more tests may be needed to determine whether the cancer has spread (metastasized).
Early detection of returning cancerAfter you have been treated for bladder cancer, it is important to have regular exams and cystoscopies to detect any recurrence early so that additional treatment can begin immediately. Researchers are studying ways to identify low-grade cancer cells without the need for a cystoscopy. Some tests for specific proteins in cancer cells (tumor markers), such as BTA and NMP22, have been approved by the U.S. Food and Drug Administration (FDA) to use to detect recurrent cancer. 2 More research is being done on these screening methods because they are not as accurate as a cystoscopy at this time. 4 Treatment OverviewThe choice of treatment and the long-term outcome (prognosis) for people who have bladder cancer depends on the stage and grade of cancer. Your doctor also considers your age, overall health, and quality of life when developing your treatment plan. Bladder cancer is usually curable if it is diagnosed while the cancer is still contained in the bladder, and about 74% of bladder cancers are diagnosed at this early stage. 2 Treatment choices for bladder cancer may include:
Initial treatmentSurgery is used to treat most stages of bladder cancer .
Chemotherapy uses medicines to destroy cancer cells. For early-stage bladder cancer, the medicines may be delivered directly into the bladder using a catheter (intravesically). For cancer that has deeply invaded the bladder or spread to lymph nodes or other organs, chemotherapy may be given orally or intravenously (IV) . Side effects may differ, depending on the medicines used and your age and overall health. For some people, depending on the stage of the cancer, chemotherapy given before cystectomy ( neoadjuvant ) leads to better results. 6 Radiation therapy, which uses high-dose X-rays or other high-energy rays to destroy cancer cells, is one of the standard treatments for certain types of bladder cancer. Radiation therapy also is used as palliative care to relieve symptoms and preserve kidney function. Home treatment can help manage some of the side effects of radiation therapy. Immunotherapy uses medicines that cause your body's immune system to attack bladder cancer cells. Bacillus Calmette-Guerin (BCG) and interferon are two of the medicines used for immunotherapy. Immunotherapy is most often used for early-stage bladder cancer. It may be used after a transurethral resection (TUR) to prevent cancer recurrence. Home treatment measures may help relieve some common side effects of cancer treatment, such as nausea, vomiting, fatigue, hair loss, stress, or sleep problems. If you have recently been diagnosed with bladder cancer, you may feel a wide variety of emotions in reaction to your diagnosis. Most people feel some denial, anger, and grief. There is no "normal" or "right" way to react to a diagnosis of cancer. You can take steps, though, to manage your emotional reaction after learning that you have bladder cancer. Some people find that talking with family and friends is comforting, while others may need to spend time alone to understand their feelings about their disease. If your emotions are interfering with your ability to make decisions about your health and to move forward with your life, it is important to talk with your doctor. Your cancer treatment center may offer counseling services. You may also contact your local chapter of the American Cancer Society to help you find a support group. Talking with other people who have had similar feelings after a diagnosis such as yours can help you accept and deal with your disease. What to think about during initial treatmentYour quality of life becomes a critical issue when considering your treatment options. Be sure to discuss your personal preferences with your urologist and oncologist when they recommend treatment. Some people with bladder cancer may be interested in participating in research studies called clinical trials. Clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. People who do not want standard treatments or who are not cured using standard treatments may want to participate in clinical trials. These are ongoing in most parts of North America and in some other countries for people with all stages of bladder cancer. When bladder cancer is found early, before it has spread outside the bladder, more than 90% of people live at least 5 years after they are diagnosed. The long-term outcome (prognosis) for men older than 65, African Americans, and those who smoke is worse than for other people who have bladder cancer. Treatment for advanced-stage bladder cancer is intended to control symptoms and increase comfort ( palliative care ), not cure the disease. For more information about specific bladder cancer treatments, see the topics:
Ongoing treatmentAfter initial treatment for bladder cancer , it is important to receive follow-up care. Your emotional reactions may continue throughout the course of your treatment, depending on your prognosis, the treatment methods used, and your quality-of-life decisions. Your urologist or oncologist will schedule regular checkups based on the stage and grade of your tumor. These checkups usually include:
People with high-grade tumors of any stage may also have an intravenous pyelogram (IVP) or computed tomography (CT urogram) done every year. Treatment if the condition gets worseBladder cancer can come back (recur) in the bladder or spread (metastasize) to other parts of the body. Recurrent bladder cancer may be treated with surgery or chemotherapy to slow cancer growth and relieve symptoms. Participation in a clinical trial may be recommended if you have been diagnosed with recurrent bladder cancer. Complementary therapiesIn addition to conventional medical treatment, some people may want to try complementary therapies, such as: Complementary therapies are not a substitute for the standard treatment recommended for bladder cancer. Before you try any of these therapies, discuss their possible benefits and side effects with your doctor. Let him or her know if you are already using any such therapies. For more information, see the topic Complementary Medicine. What To Think AboutMost treatments for bladder cancer cause side effects. Side effects may differ, depending on the type of treatment used and your age and overall health. Your doctor can talk to you about your treatment choices and the side effects associated with each treatment.
Home treatment measures may help you manage the side effects. Palliative careIf your cancer gets worse, you may want to think about palliative care . Palliative care is a kind of care for people who have illnesses that do not go away and often get worse over time. It is different from care to cure your illness, called curative treatment. Palliative care focuses on improving your quality of life, not just in your body but also in your mind and spirit. Some people combine palliative care with curative care. Palliative care may help you manage symptoms or side effects from treatment. It could also help you cope with your feelings about living with a long-term illness, make future plans around your medical care, or help your family better understand your illness and how to support you. If you are interested in palliative care, talk to your doctor. He or she may be able to manage your care or refer you to a doctor who specializes in this type of care. For more information, see the topic Palliative Care. End-of-life issuesSome people with advanced-stage disease may choose not to have treatment focused on prolonging life because the time, costs, and side effects of treatment may be greater than the benefits. Making the decision about stopping medical treatment to prolong life and shifting the focus to end-of-life care can be difficult. For more information, see the topics: PreventionBladder cancer cannot be prevented, but you may be able to reduce some of your risk factors for developing it.
Home TreatmentIf you are receiving radiation therapy or chemotherapy to treat any stage of bladder cancer , you can use home treatment to help manage the side effects that may be caused by these treatments. Home treatment may be all that is needed to manage the common problems listed below. If your doctor has given you instructions or medicines to treat these symptoms, be sure to follow them. In general, healthy habits such as eating a balanced diet and getting enough sleep and exercise can help control your symptoms.
Other issues that may arise include:
Many people with bladder cancer face emotional issues as a result of their disease or its treatment.
Bladder cancer rarely causes pain, and not all forms of cancer treatment cause pain. If pain occurs, many treatments are available to relieve it. If your doctor has given you instructions or medicines to treat pain, be sure to follow them. Home treatment for pain, such as a nonsteroidal anti-inflammatory drug (NSAID) or an alternative therapy like biofeedback , may improve your physical and mental well-being. Be sure to discuss with your doctor any home treatment you use for pain. Some people with advanced-stage disease may choose not to have treatment because the time, costs, and side effects of treatment may be greater than the benefits. Making the decision about stopping medical treatment to prolong life and shifting the focus to end-of-life care can be difficult. For more information, see the topics: MedicationsMedicines may be used to control the growth of bladder cancer cells and to relieve symptoms. Chemotherapy uses medicines to destroy cancer cells. Immunotherapy uses medicine that causes your body's immune response to attack cancer cells in your bladder. Medication ChoicesChemotherapy may be taken by mouth (orally), injected into a vein ( intravenous, or IV ), or put into the bladder through a urinary catheter (intravesically). Chemotherapy can kill cancer cells both inside and outside the bladder area. Medicines through a vein (IV)
Medicines through a catheter into the bladder
What To Think AboutMedicines, alone or in combination, may be delivered directly into the bladder using a catheter (intravesically). Adjuvant chemotherapy may be used with transurethral resection (TUR) of the bladder. Chemotherapy is also used when cancer cannot be controlled with surgery. Most chemotherapy causes some side effects. Home treatment may be all that is needed to manage your symptoms. But some people may need medicines to control nausea and vomiting. If your doctor has given you instructions or medicines to treat your symptoms, be sure to follow them. In general, healthy habits such as eating a balanced diet and getting enough sleep and exercise can help control your symptoms. Clinical trials are research studies to look for ways to improve treatments for bladder cancer. Experts are doing studies on:
Ask your doctor about taking part in a clinical trial. SurgeryThere are two main surgeries for bladder cancer .
Surgery ChoicesSurgery to remove cancer
Surgery to remove bladder
Following surgery to remove the bladder, your surgeon will create a new channel for urine to pass from your body. 7
Noncontinent diversions are simpler and may have fewer complications either right after surgery or in the coming months and years. Continent diversion reservoirs eliminate the need for a urine storage bag to be worn outside the body. What To Think AboutSide effects from your surgery can include problems with bowel functioning, such as constipation or diarrhea. Your ability to have or enjoy sexual intercourse may also be affected. Adhesions may develop after surgery, and a bowel obstruction may occur as a complication if surgery was extensive. Other TreatmentRadiation treatment for bladder cancer uses high-energy X-rays to kill cancer cells and shrink tumors. External beam radiation comes from a machine outside the body. The machine aims radiation at the area where the cancer cells are found. Internal radiation uses needles, seeds, wires, or catheters that contain radioactive materials placed close to or directly into the bladder. Which treatment you receive will depend on the type and stage of your cancer. Photodynamic therapy (PDT) is being studied as a treatment for bladder cancer. PDT uses laser light and a special light-activated substance (Photofrin) to kill cancer cells. Results of early studies with photosensitizers show that PDT may be effective in treating recurrent noninvasive bladder cancer. 2, 8 Until all the drug is out of the body, the skin can get a sort of sunburn after even short exposures to light. This effect can last several weeks. 9 Other Treatment Choices
What To Think AboutSome people with bladder cancer may be interested in taking part in research studies called clinical trials. Clinical trials are designed to find better ways to treat cancer patients and are based on the most up-to-date information. People who do not want standard treatments or who are not cured using standard treatments may want to take part in clinical trials. These are ongoing in most parts of the United States and in some other countries for people with all stages of bladder cancer. The combination of conventional medical treatment and complementary medicine is an approach that is sometimes termed integrative medicine, in which conventional and complementary therapies work together for the best outcome.
