Occurring most frequently in men, bladder cancer is among the most common types of cancer and affects nearly 70,000 U.S. adults annually. Of this group, 90 percent of this cancer occurs in adults over the age of 55. Survival rates for bladder cancer vary depending on the stage of the cancer at the time of cancer diagnosis. While survival rates for later stage cancers that have metastasized into the lymphatic system are relatively low, there is good news — usually, the prognosis isn’t all too dire. The average five-year survival rate for bladder cancer is 77 percent.
