The bladder is located in the pelvis. It collects and stores urine and
has a muscular wall that allows it to contract and expand. The American
Cancer Society estimates that 74,000 new cases of bladder cancer will
be diagnosed in the United States in 2015 and 16,000 people will die of the disease.
Cancer limited to the lining of the bladder is called non-muscle invasive bladder cancer (NMIBC).
This type of cancer is sometimes called superficial bladder cancer.
More than 75 percent of bladder cancer is diagnosed as a NMIBC and it
has an excellent survival rate. Muscle invasive bladder cancer
penetrates the layers of muscles in the bladder and is more likely to
spread to other parts of the body but is often still quite curable.
Bladder cancer is four times more common in men than in women. It is two
times more common in Caucasians than African-Americans.
