Detailed explanation of the pathogenic factors of bladder tumors

The occurrence of bladder tumors is a complex, multi-factorial, multi-step pathological process with serious hazards. Therefore, it is most important to understand the causes of bladder tumors and prevent them early.

What are the causes of bladder tumors? Relevant experts point out that there are both internal genetic factors and external environmental factors. Smoking is currently the most confirmed risk factor for bladder tumors. About 30% to 50% of bladder tumors are caused by smoking. Smoking can increase the risk of bladder tumors by 2 to 4 times, and the risk rate is proportional to the intensity and duration of smoking.

Another important risk factor is long-term exposure to industrial chemical products. Occupational factors are the earliest known risk factors for bladder cancer. About 20% of bladder cancers are caused by occupational factors, including textile, dye manufacturing, rubber chemistry, pharmaceutical preparations 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.

In fact, there are many causes of bladder tumors, including chronic infection (bacterial, schistosomiasis and HPV infection, etc.), the use of the chemotherapy drug cyclophosphamide (latent period of 6 to 13 years), the 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, etc.

The above is an introduction to the causes of bladder tumors. The relevant article at home points out that bladder tumors may also be related to genetics. Those with a family history have a significantly increased risk of developing bladder tumors. The incidence of bladder tumors in patients with hereditary retinoblastoma is also significantly increased.
