Many causes can contribute to bladder cancer:

  • Chronic bladder infections: eg caused by recurring urinary tract infections, bladder stones, indwelling urinary catheter.
  • Schistosomiasis (Bilharzia) is a common infectious disease in tropical regions. Worm larvae from water bodies, when swimming through the skin or drinking contaminated water through the gastrointestinal tract, penetrate the human body and affect its various organs and systems. Including the bladder. Without treatment, this condition can lead to bladder cancer. The WHO estimates that schistosomiasis affects approximately 200 to 300 million people, primarily in tropical regions.
  • Smoking: Smokers are 6 times more likely to develop bladder cancer than non-smokers.
  • Chemical substances: long-term contact with known chemicals (eg beta-naphthylamine or benzidine used in the rubber and aniline industry) increases the risk.
  • Medications: It has been proven that some drugs contribute to the occurrence of bladder carcinoma: for example, cyclophosphamide, phenacetin, which as non-steroidal antirheumatic drugs since 1988 are no longer allowed into practice.
