Detecting Bladder Cancer
Almost 64,000 people will develop bladder cancer this year. B;adder cancer is
three times more common in men, and those who smoke are at the highest risk.
While bladder cancer can be cured when found early enough, it is estimated that
over 13,000 people will die this year from the disease.
Blood in the
urine or a significant change in the frequency of urination may be an indication
of bladder cancer. To confirm bladder cancer, a doctor will usually perform a
cystoscopy, the best available method for detecting bladder cancer. During this
procedure, a thin tube with a lens is inserted into the bladder through the
urethra. Then, the doctor looks for any abnormal growths in the bladder and
removes a piece of tissue to be checked for cancer cells.
A new way of
detecting bladder cancer is a urine test, which is being developed by Italian
researchers. It measures the amount of an enzyme called telomerase, a key factor
in cellular repair. In a new study, published on October 26 in the Journal of
the American Medical Association, researchers found that they can detect
abnormal levels of this enzyme about 90 percent of the time, indicating a high
likelihood of bladder cancer.
This test represents a promising and
potentially important contribution to the early diagnosis of bladder.
