What is bladder cancer?
Bladder cancer is abnormal growth of the cells that line
the inside of the bladder. The growth is called a bladder
tumor.
A tumor may be either invasive or noninvasive. A
noninvasive tumor is usually a small, wartlike growth that
has not yet grown into the bladder wall. If a tumor is
invasive, the cancer cells may spread into the bladder wall
and then to other organs through the bloodstream and
lymphatic system.
Bladder cancer affects men 3 times more often than women.
Bladder tumors are most likely to develop in white men over
the age of 50.
How does it occur?
In most cases, bladder tumors occur when the cells lining
the urinary tract are exposed to cancer-causing chemicals in
the urine. Chemicals in the urine can come from:
- cigarette smoking (the most common cause)
- the workplace, such as rubber, aniline dye, some
textiles, paint, and, rarely, hairdressing supplies
- overuse of pain medicines that contain phenacetin (these
medicines are no longer available in the US).
What are the symptoms?
Symptoms of bladder cancer are:
- blood in the urine
- pain when you urinate
- frequent need to urinate
- trouble starting to urinate
- lower back pain.
How is it diagnosed?
Your healthcare provider will ask about your symptoms and
examine you. Your urine will be tested for the presence of
blood or infection. Your provider may also look for
abnormal cells in the urine.
You will probably have an exam called a cystoscopy. During
this exam your provider passes a slim, flexible, lighted
tube called a cystoscope through the urethra and into the
bladder to look inside your bladder. The urethra is the
passageway that carries urine from your bladder to outside
the body.
During this test your provider will probably do a biopsy.
This involves removing a small piece of bladder lining
tissue. The tissue is checked to see if it is cancerous.
You may also have the following types of X-rays or scans:
- intravenous pyelogram (an X-ray study of the whole
urinary tract using X-rays and a dye injected into a
vein in your arm)
- CT scan of your abdomen
- an ultrasound of the kidneys.
If cancer is found, you may have more tests to see if cancer
cells have spread within the bladder or to other parts of
the body. For example, you may have a chest X-ray or a bone
scan.
How is it treated?
Treatment of a bladder tumor depends first on whether it is
invasive. For an early, noninvasive tumor, your healthcare
provider will try to destroy the tumor by burning it off
with a high-frequency electrical current passed through a
cystoscope. This process is called fulguration. For small
tumors this may be the only treatment that is needed. In
another process, chemicals or other medicines may be put
into your bladder to destroy the cancer cells.
Large tumors that have gotten into the muscle of the bladder
wall must be surgically removed. Sometimes all or part of
the bladder is removed. This type of surgery is called a
cystectomy. It is performed under general anesthesia. The
ureters (tubes draining urine from the kidney to the
bladder) are now connected to a surgically devised reservoir
and then to an opening made in your abdomen. A bag is
attached to this opening to collect urine. If the whole
bladder is removed, the bag, or external bladder, will be
permanent. In some cases a new bladder may be made from a
piece of intestine.
Other treatments for invasive tumors include radiation
therapy to the bladder or chemotherapy to help destroy
cancer cells that may have spread beyond the bladder.
How long will the effects last?
As with other forms of cancer, the treatments for bladder
cancer that are most successful are those that begin before
the disease has spread. This is why it is important to
catch the cancer as early as possible. See your healthcare
provider as soon as you detect any symptoms of bladder
cancer.
If you have a noninvasive tumor (superficial bladder
cancer), your chances of cure are very good. You should,
however, have regular cystoscopy exams because small tumors
often come back or new ones may develop.
The removal of a large invasive tumor by partial bladder
resection reduces the size of the bladder. This means the
bladder holds less urine than before the surgery and you
will need to urinate more often.
How can I take care of myself?
- Follow your healthcare provider's instructions and take
the full course of your prescribed medicines.
- If your entire bladder is removed, keep the external
opening clean to prevent infection. Empty the external
bladder bag before it gets too full.
- Early in your treatment, consider talking with a
counselor about the changes in your body and your body
image. Some people become depressed over these changes.
Talking with someone early can help you avoid more
involved problems later.
- Maintain a positive outlook. If necessary, make
lifestyle changes that include a healthy diet, lots of
liquids, regular exercise and rest, reduction of stress,
and time for activities that you enjoy.
- Do not smoke.
How can I help prevent bladder cancer?
- If you smoke, stop smoking.
- Use protective measures when you are likely to be exposed
to industrial chemicals.
