Bladder Cancer

Bladder cancer is the most common malignant tumor of the urinary system, with the highest incidence rate. The cause of its onset is unclear, and it is generally believed to be related to frequent exposure to carcinogens such as naphthylamine and benzidine. Dyes, rubber, plastic products, paints, detergents, etc. that are commonly used in daily life also have potential carcinogenic risks. Smoking is not only harmful to the respiratory system, it can also cause bladder cancer. In addition, certain diseases such as bladder leukoplakia, glandular cystitis, urethral stones, and urinary retention may also induce bladder cancer. The incidence of bladder cancer in men and women is approximately 5: 2, and approximately 54500 new cases are reported each year in the United States (estimated in 1997).
