Bladder Cancer
Bladder cancer affects approximately 55,000 adults each year — about twice as many men as women, and almost all are over 40 years of age.
By Rear Adm. Joyce Johnson, D.O
The bladder is the “holding tank” for urine. The kidneys filter
waste products from the blood. These products, dissolved in water,
form urine. Urine flows from each kidney through each ureter to the
bladder, located in the lower abdomen. It leaves the body through
the urethra.
Any time you see blood in your urine (i.e., the urine is red or
brownish-orange), see your doctor immediately. This could be a sign
of a common urinary tract infection, but it also could be a symptom
of bladder cancer. Frequent or painful urination also can accompany
bladder cancer.
If your health practitioner suspects bladder cancer, he or she will
take a complete history and do a physical examination, including
tests on the urine. You probably will be referred to a urologist for
a cystoscopy, which involves inserting a small fiber optic tube into
the urethra to see the inside of the bladder. During the cystoscopy,
biopsies may be taken so a pathologist can determine whether the
cells are cancerous. Your doctor also could order an intravenous
pyelogram, which involves injecting a dye into the veins that, on
x-rays, will highlight the outline of the urinary tract and help
identify any masses. If bladder cancer is diagnosed, other tests
might be necessary to determine how advanced (what “stage”) it is.
The stage is a major factor in determining a treatment plan.
Treatment generally involves surgical removal of the cancer. If it
is small and superficial, it can easily be removed, leaving the
bladder intact; sometimes all or part of the bladder must be
removed. If all of the bladder is removed, the surgeon will create a
pouch to hold the urine and a tube through which it can exit the
body. Even if the cancer is so advanced it is not possible to
surgically remove the entire tumor, additional treatments are
available. For some patients, additional treatments are recommended
after surgery.
Radiation therapy could involve inserting radioactive material
directly into the bladder (which must take place in the hospital) or
exposing the patient to radiation from a machine similar to an x-ray
machine (which requires nearly daily out-patient treatments for a
month or two). Occasionally, radiation therapy is done before
surgery to shrink the tumor. Chemotherapy and biological therapies
also are frequently used, with some medications inserted directly
into the bladder and others injected intravenously. Surgery,
radiation, chemotherapy, and biological therapy often are combined
in a treatment plan tailored to an individual patient.
Bladder cancer can run in some families. Smoking more than doubles
your chances of getting bladder cancer. Exposure to some
occupational chemicals or to arsenic also increases your risk.
Early Detection Is Always Key
■ When diagnosed early, bladder cancer is very responsive to
treatment. For more information, visit
