Symptoms of recurrence of bladder cancer after surgery

Where does bladder cancer recur after surgery? Bladder cancer is a malignant tumor that originates from the bladder, which means that abnormal cells proliferate in large numbers without control. The most common bladder cancer cells come from the mucosal epidermis of the bladder. The main risk factor for bladder cancer is genetic influence. In addition, people who smoke or have long-term contact with certain dyes, gasoline or other chemicals also have a higher risk.

1. Hematuria. Bladder cancer often presents hematuria as the first symptom. It can be visible or microscopic hematuria. Hematuria is usually painless, intermittent, and continuous, and is sometimes accompanied by blood clots. The diverse manifestations of hematuria can easily lead to misdiagnosis. For example, intermittent hematuria is often considered to be the disappearance of the disease when the hematuria stops, and further treatment is not given in time. In addition, the amount of hematuria and the duration of hematuria are related to the malignancy of the tumor and the size, range, and number of the tumor. The progression of the disease or the larger range of lesions or combined infections may be accompanied by urinary tract irritation symptoms, discharge of slough-like substances, discharge of lumps, blood clots, or difficulty urinating due to lumps blocking the urinary tract, dripping, or even urine retention.
2. Urinary tract irritation. Urinary tract irritation symptoms rarely occur in early bladder cancer. They can appear earlier when accompanied by urinary tract infection or tumors occur in the bladder trigone. In addition, bladder irritation symptoms also reveal the possibility of bladder carcinoma in situ. Therefore, patients with bladder irritation who lack evidence of infection should actively undergo a comprehensive examination to make an early diagnosis.
3. Other symptoms: If the tumor infiltrates the ureteral opening or grows at the ureteral opening, it can cause ureteral dilatation, which in turn leads to hydronephrosis and kidney enlargement. When bladder cancer metastasizes to the lungs, liver, and bones, corresponding symptoms may appear, such as cough, shortness of breath, abnormal liver function, pain in the liver area, and bone pain somewhere. When bladder cancer is very serious, it may also be complicated by bladder cancer pain, severe hematuria, and urinary retention.
