Several common symptoms of bladder cancer

It is understood that there are many people suffering from bladder cancer in real life, especially workers who have been engaged in the production of aromatic amines, dyes, rubber, aluminum, and leather for a long time are prone to bladder cancer, which brings great harm to their health. What are the common symptoms of bladder cancer ? The following will tell you about the common symptoms of bladder cancer.

Common bladder cancer symptoms include:

1. Symptoms of urinary obstruction: Large tumors, tumors at the bladder neck, and blood clots can cause urinary difficulties or even urinary retention. Tumor infiltration of the ureteral orifice can cause upper urinary tract obstruction. Symptoms of bladder cancer include low back pain, hydronephrosis, and renal impairment.

2. Hematuria: Painless macroscopic hematuria is the most common symptom of bladder cancer, which may occur in more than 80% of patients, of which 17% have severe hematuria, but 15% may only have microscopic hematuria at the beginning. Hematuria is mostly intermittent throughout the whole process. Symptoms of bladder cancer may also manifest as initial hematuria or terminal hematuria. Some patients may excrete blood clots or necrotic tissue. The duration of hematuria and the amount of bleeding are related to the malignancy, stage, size, number, range, and morphology of the tumor, but they are not necessarily proportional. Carcinoma in situ often manifests as microscopic hematuria, while hematuria in urachal carcinoma of the bladder may not be obvious. Bladder tumors of non-urothelial origin may not have hematuria if the lesions do not penetrate the bladder mucosa.

3. Bladder irritation symptoms: frequent urination, urgent urination, and painful urination, accounting for about 10%, are related to the widespread distribution of carcinoma in situ and invasive bladder cancer, especially when the lesions are located in the bladder triangle, which are all symptoms of bladder cancer. Therefore, long-term "cystitis" that cannot be cured should be alert to the possibility of bladder cancer, especially carcinoma in situ.

The above are the common symptoms of bladder cancer. I hope it will help you understand bladder cancer. Once the above symptoms of bladder cancer appear, you must go to the hospital immediately for active treatment to avoid delaying the disease and missing the best time for treatment.
