What is the cause of bladder cancer?

Bladder cancer is a malignant tumor with a high incidence rate. The most obvious symptom after the onset of the disease is hematuria, which is mostly painless. In addition to hematuria, patients also have urination problems and urination pain. So what is the cause of bladder cancer? Let's take a look together.

The causes of bladder cancer are very complex, including internal and external factors, such as internal genetic factors and external environmental factors, which can lead to the occurrence of bladder cancer.

For bladder cancer, the two most obvious risk factors are smoking, and there is also a saying that it is occupational exposure to aromatic amine chemicals. Among them, smoking is the most certain cause of bladder cancer. Among bladder cancer patients, 30% to 50% of them are caused by smoking. According to research, smoking increases the risk of bladder cancer by 2 to 6 times. The longer the smoking time, the higher the incidence of bladder cancer. Another important cause is related to occupational exposure. There is data to prove that some chemicals such as aniline, diaminobenzene, 2-naphthylamine, 1-naphthylamine, etc. are carcinogens of bladder cancer. If people are exposed to these chemicals for a long time, they will increase the chance of bladder cancer. Bladder cancer caused by occupational factors can account for 25% of the total number of bladder cancer patients. Industries such as aluminum products, coal tar, asphalt, dyes, rubber, and coal gasification have a significantly higher chance of bladder cancer than other occupations.

Bladder cancer is very harmful. Once diagnosed, it must be treated in time. The treatment can be selected according to the situation. Generally, non-muscle-invasive urothelial carcinoma can be treated with urethral bladder tumor transurethral resection, and bladder instillation can be performed after surgery to prevent recurrence. For muscle-invasive urothelial carcinoma and bladder squamous cell carcinoma, adenocarcinoma, etc., it is suitable to use total cystectomy for treatment, and partial cystectomy can also be used for treatment according to the situation. The specific treatment plan can be determined according to the specific situation of the patient.

The above are the common causes of bladder cancer, which are mainly caused by smoking and the hazards of some chemical substances. Therefore, in order to better prevent bladder cancer, it is best not to smoke. For some occupations that often require contact with carcinogenic chemicals, you must take protective measures to prevent the occurrence of bladder cancer.
