What are the symptoms before death from advanced bladder cancer? 5 ways to prevent bladder cancer

Bladder cancer is a very scary tumor disease, and many patients die from it. There are many causes of advanced bladder cancer, but some patients who are frequently exposed to carcinogens are more likely to develop bladder cancer. For example, patients who are frequently exposed to naphthylamine and benzidine are more likely to develop this disease. In addition, some common dyes in daily life are the culprits of bladder cancer. (3) Symptoms of advanced bladder cancer include urinary retention, where a large amount of urine accumulates in the bladder and cannot be discharged, blocking the bladder neck or urethra. The main symptoms are inability to urinate or difficulty in urinating. In severe cases, urination may not last for a week.

When does bladder cancer cause blood in urine?

Bladder cancer may also cause symptoms such as frequent urination, urgent urination, painful urination, or difficulty urinating. If you have these symptoms, you should pay attention to them and go to the hospital for a complete urine routine, abdominal ultrasound or CT, or MRI examination. When the tumor grows to a certain size, it will be completely painless and have hematuria that can be seen with the naked eye. This is its more characteristic symptom. Bladder cancer may cause hematuria regardless of its size.

How to detect and diagnose bladder cancer early

B-ultrasound can detect tumors larger than 0.5 cm, but it cannot be relied upon to confirm bladder cancer. For further diagnosis, pathology must be obtained through surgery or cystoscopy to finally confirm bladder cancer. Cystoscopic biopsy is the most reliable method for diagnosing bladder cancer, which can clarify the size, number, shape and growth pattern of the tumor and its relationship with surrounding tissues. Bladder color ultrasound, bladder CT and cystoscopy can be used to detect and confirm early bladder cancer.
