Bladder carcinomas are malignant neoplasms of the bladder.
In about three-quarters of patients, at the first examination, a superficial tumor that does not penetrate into the muscular layer of the bladder wall is found. In the remaining quarter, the tumor has already grown into the muscle tissue or has affected other organs (invasive tumor).
Men are more than 2 times more likely to suffer from this disease than women, in addition, the risk of getting sick increases with increasing age. Contributing factors are chronic inflammation of the bladder, smoking, taking certain medications, contact with various chemicals. Bladder carcinoma is considered an occupational disease, so in each case of bladder carcinoma it is required to find out if there is an occupational disease.

(for men - 4.6%, women - 2% of all new cancer cases in 2007 - 2008 according to the Robert Koch Institute). In Germany, with approximately 16,000 new cases per year, bladder cancer is one of the most common types of cancer. Men get sick on average at the age of 69 years, women - at the age of 73 years.
