What causes bladder cancer?

Long-term exposure to chemical carcinogens According to statistics, the incidence of bladder cancer among workers engaged in dye operations is 15 to 32 times that of the general population. The reason is that the dyes they are exposed to for a long time contain carcinogens such as 2-naphthylamine, 1-naphthylamine, benzidine, and 4-aminobiphenyl. These carcinogens can enter the body through the skin, respiratory tract, or digestive tract, act in the bladder, cause the bladder mucosa to become malignant, and induce bladder cancer. The cause of bladder cancer is complex, and it is difficult for patients to determine the specific cause. Environmental factors and genetic factors are closely related. There are many causes of bladder cancer, and the causes may be complex, such as genetic factors, environmental factors, and other reasons. The specific reasons are as follows:

What is the chance of bladder cancer recurring?

If it is a bladder tumor T1 stage, then considering that at this time, it is limited to the lamina propria, considering this time, actively cooperate with the treatment, and provide reasonable care in the later stage, the prognosis is still good. Tumor treatment needs to be relatively timely, and the prognosis is relatively good. The recurrence rate of non-basal invasive bladder tumors before T1 stage within five years is 60%-70%. The treatment of bladder cancer T1G3 is more difficult.
