Every year, almost 30,000 people in Germany are newly diagnosed with bladder cancer. Men are affected three times more frequently than women. In 7 out of 10 people affected, the tumor is limited to the mucous membrane and has not yet grown into the muscle layer. Risk factors primarily include smoking, certain chemical substances or chronic inflammation of the urinary bladder. However, a frequent occurrence of bladder cancer in the family also poses a higher risk of developing the disease oneself. If detected early, bladder cancer is very curable. Minimally invasive procedures are used.
