Bladder cancer is a cancerous tumor in the bladder. In most cases, the bladder cancer develops from the transitional cells that line the inside of the bladder. Most of the symptoms of bladder cancer can also occur with non-cancerous conditions and there may be blood in the urine or painful, involuntary, or frequent urination.
Other symptoms that can occur with this disease are abdominal pain, anemia, bone pain or tenderness, lethargy, or fatigue. In many cases, the reason why a bladder cancer develops is not known. Most bladder cancers occur in people over the age of 50. Also, it is four times more common in smokers than non-smokers. Substances used in the rubber and dye industries have been linked to bladder cancer. Genetic factors also contribute to the risk of developing bladder cancer.
The outlook for early stage cancers is fairly good. The choice of treatment depends on the stage of the tumor, the severity of the symptoms, and the presence of other medical conditions.
