6 major risk factors for bladder cancer

Studies have found that more than 80% of bladder cancer cases are related to carcinogenic risk factors. Currently, it is believed that the main risk factors for bladder cancer include smoking, occupational factors, drug factors, family history, urinary tract diseases and unhygienic drinking water.

1. Smoking: Smoking is the most important risk factor for bladder cancer. The risk of bladder cancer in smokers is 2 to 4 times that of non-smokers. The risk of developing bladder cancer is related to the amount, duration and degree of inhalation of cigarettes.

2. Occupational factors: Occupational factors are one of the risk factors for bladder cancer. Workers engaged in the production of aromatic amines, dyes, rubber, aluminum, and leather have a higher risk of bladder cancer than ordinary people.

3. Drug factors: Drugs can increase the risk of bladder cancer. For example, taking large amounts of painkillers containing phenacetin can increase the incidence of bladder cancer.

4. Family history: Bladder cancer has a certain familial incidence. Studies have found that the risk of bladder cancer in the direct relatives of bladder cancer patients is about twice that of those without a family history, and the risk is even higher for the direct relatives of young bladder cancer patients.

5. Urinary tract diseases: Long-term chronic stimulation of the urethral epithelium or increased levels of carcinogens in the urine caused by human metabolic products can cause the urethral epithelium to proliferate and become cancerous, increasing the risk of bladder cancer.

6. Unhygienic drinking water: Drinking tap water that has been disinfected with chlorine and contains chlorination by-products can increase the risk of bladder cancer.
