How long does it take for bladder cancer to recur after surgery?

Bladder cancer refers to a malignant tumor that occurs on the bladder mucosa. It is the most common malignant tumor in the urinary system and one of the top ten common tumors in the body. The pathological types of bladder cancer include bladder urothelial carcinoma, bladder squamous cell carcinoma, bladder adenocarcinoma, and other rare bladder clear cell carcinoma, bladder small cell carcinoma and bladder cancer. The most common is bladder urothelial carcinoma, accounting for about 90% of the total number of bladder cancer patients. Generally speaking, bladder cancer refers to bladder urothelial carcinoma, which was formerly known as bladder transitional cell carcinoma.

Cause: The cause of bladder cancer is complex, including both internal genetic factors and external environmental factors. Two obvious risk factors are smoking and professional exposure to aromatic amine chemicals. Smoking is currently the most certain risk factor for bladder cancer. 30% to 50% of bladder cancers are caused by smoking. Smoking increases the risk of bladder cancer by 2% to 6 times. As the smoking time increases, the incidence of bladder cancer also increases significantly. Another important risk factor is related to a series of occupations or occupational exposures. Aniline and diaminobenzene have been confirmed to be carcinogens of bladder cancer. Patients who are exposed to these chemicals for a long time have an increased probability of developing bladder cancer. Bladder cancer patients caused by occupational factors account for about 25% of the total number of bladder cancer patients.

Bladder cancer is a disease that is prone to recurrence. The surgical treatment of this cancer is not particularly complicated, but the probability of recurrence is very high. Because there are many pathological types of bladder cancer, such as urothelial carcinoma. This type of bladder cancer is prone to metastasis because it is prone to infiltration metastasis, leading to recurrence. After surgical treatment of bladder cancer, human cancer cells are in a low stage. The general recurrence time has a lot to do with the human body constitution and surgical treatment method. If the human body constitution is poor and the surgical treatment is not perfect, it will recur within three months.
