What are the clinical symptoms of bladder cancer

The most obvious early symptom of bladder cancer is hematuria, and the incidence rate is very high. There are two types of hematuria: macroscopic hematuria and microscopic hematuria. Macroscopic hematuria refers to bloody urine that can be seen with the eyes, and microscopic hematuria refers to urine that contains red blood cells under a microscope. Bladder cancer hematuria is mostly painless and intermittent, most of which are full-course hematuria, and a few are terminal hematuria. Hematuria accompanied by frequent urination and urgency is rare.

As the disease progresses, it may manifest as: Advanced bladder cancer may infiltrate around the pelvic floor or metastasize to distant sites. When the tumor infiltrates the posterior urethra, prostate, and rectum, corresponding symptoms will appear. When the tumor is located at one ureteral orifice, it causes ureteral orifice infiltration, which may cause ureteral dilatation and hydronephrosis on one side.
