Non-invasive bladder cancer does not necessarily recur. Early stage non-invasive bladder cancer patients can improve their survival rate after timely treatment with surgical resection as well as adjuvant radiotherapy and chemotherapy. After reasonable treatment, the possibility of recurrence will be reduced. Therefore, patients with non-invasive bladder cancer may not necessarily recur. However, it should be noted that non-invasive bladder cancer belongs to malignant tumor disease, and if reasonable treatment is not taken in time, the cancer cells are more invasive and may metastasize. At this time, even after surgical removal of the tumor or drug treatment, the tumor still has a greater recurrence rate. Patients with non-invasive bladder cancer should go to hospital for consultation in time, choose appropriate methods to treat the disease and prevent its aggravation, which can reduce recurrence to a certain extent.
