The inheritance pattern of bladder cancer

Among genetic factors, those with a family history have a significantly higher risk of bladder cancer than those without a family history. In addition, the incidence of bladder cancer in patients with hereditary retinoblastoma is also significantly increased. Among environmental factors, the two most obvious risk factors are smoking and long-term exposure to industrial chemical products.

Smoking is currently the most certain risk factor for bladder cancer, and its risk rate is proportional to the daily amount of smoking and the length of smoking history. Long-term exposure to certain carcinogenic chemicals is also a risk factor for bladder cancer, such as textile, dye manufacturing, rubber chemistry, pharmaceutical preparation and pesticide production, paint, leather and aluminum, iron and steel production. The accumulation of diesel engine exhaust can also increase the risk of bladder cancer. But it does not mean that all people who are exposed to these chemical industries will get bladder cancer. To truly find out the cause of bladder cancer, further research and confirmation by the medical community is needed.
In addition, chronic urinary tract infection, residual urine and long-term foreign body stimulation (indwelling catheter, stones) are closely related to the occurrence of muscle-invasive bladder cancer; the use of chemotherapy drug cyclophosphamide, abuse of painkillers containing phenacetin (more than 10 years), pelvic radiotherapy, long-term drinking of water with high arsenic content and chlorine disinfected water, coffee, artificial sweeteners and hair dyes may also be the cause of bladder cancer.
