What are the symptoms of bladder cancer?

Bladder cancer is also a type of malignant tumor. The effectiveness of treatment depends mainly on how quickly the disease is discovered. If it is discovered and treated early, the disease can be well controlled, but if it is treated late, it will be more troublesome. Therefore, early detection is very important. Now we will introduce the common symptoms of bladder cancer to you, and hope that you can learn to judge.

In general, the main symptoms of bladder cancer are:

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

Symptoms of urinary obstruction: Large tumors, tumors at the bladder neck, and blood clots can cause difficulty in urination or even urinary retention. Symptoms of bladder cancer can cause upper urinary tract obstruction, low back pain, hydronephrosis, and renal impairment.

Hematuria: Painless macroscopic hematuria is the most common symptom, 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, and may also manifest as initial hematuria or terminal hematuria. Some patients may discharge 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, and 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. This is one of the more important symptoms of bladder cancer.

Through our introduction, I believe everyone has a more systematic understanding of this. Please pay attention to the changes in your body in your daily life, and don't always hold your urine, because this may also be one of the causes of this disease. The best thing for everyone is to exercise more, don't sit for a long time, and take active prevention. Finally, I wish you all good health.
