Usually, a bladder biopsy is performed to check for cancer of the bladder or urethra. The symptoms of bladder cancer typically are:
- painful urination
- frequent urination
- blood in the urine
- lower back pain
These symptoms can be an indication of something less sinister than cancer, such as an infection. Equally your biopsy might not may indicate something other than cancer, such as cysts, ulcers. bladder diverticula, or balloon-like growths on the bladder. Therefore, a bladder biopsy is only performed if your doctor strongly suspects cancer and has for example, found cancer through other tests.
Before a bladder biopsy, your doctor will carry out some other routine tests such as a test of your urine and some imaging tests, such as an X-ray or CT scan, before the procedure. Because these scans and tests alone cannot determine whether the growth is a cancerous growth, a bladder biopsy reviewed in a laboratory, is necessary.
