Bladder cancer is not a typical hereditary disease, but it does have a certain genetic predisposition. Although genetic factors play a role in the development of bladder cancer, the exact genetic mechanisms are not yet fully understood. Individuals who have close relatives with bladder cancer are at a higher risk of developing the disease compared to the general population, and approximately 5-10% of bladder cancer cases exhibit a familial genetic tendency. Additionally, mutations in certain genes, such as BRCA1 and BRCA2, have been associated with an increased risk of familial bladder cancer. The occurrence of bladder cancer is also influenced by numerous other factors, including smoking, occupational exposure, and chronic bladder diseases. Therefore, when considering the genetic risk of bladder cancer, multiple factors should be taken into account comprehensively.
