Does bladder cancer require cystoscopy?

This depends on how long it has been since the treatment. Generally, the examination is done within the first three months after the treatment. When B-ultrasound shows whether there is a space-occupying lesion in the bladder, if there is a space-occupying lesion, it may be bladder cancer, glandular cystitis, or polyps, stones, etc., a cystoscopy is required to confirm the diagnosis. If the cystoscopy shows a tumor, pathology can be done to determine whether it is benign or malignant. Of course, the pathological results are ultimately required. The biopsy is sent for pathological examination, and generally a diagnosis of bladder cancer can be made within one week.

Why does bladder cancer cause back pain?

If patients with bladder cancer experience low back pain, it may be caused by the metastasis of bladder cancer to the lumbar spine. It is best for patients to undergo a whole-body bone radionuclide scan to confirm the diagnosis. Some patients with bladder cancer may have widespread dissemination in the abdominal and pelvic cavity, thus causing invasion and compression of the nerves in the abdominal and pelvic cavity, which may also manifest clinically as low back pain. Hematuria is the earliest symptom of bladder cancer. The biggest feature of this type of hematuria is that it is painless and occurs for no reason.

What are the mid-stage symptoms of bladder cancer in men?

There are no specific symptoms in the early stages of male bladder cancer, so it is difficult to detect bladder cancer in the early stages. Patients may show symptoms such as frequent urination, which is manifested by an increase in the number of urinations. However, many diseases can cause frequent urination, such as prostatitis and prostatic hyperplasia in men, or a natural decrease in bladder capacity with age, which can also cause physiological frequent urination. Therefore, it is difficult to detect bladder cancer through a single examination of frequent urination. For bladder cancer, if the tumor is large or a blood clot forms and blocks the urethra, a series of symptoms such as urinary retention and difficulty urinating will occur. It is recommended that you should actively go to the hospital for a detailed examination to make a clear diagnosis and then treat the symptoms. Because in the middle stage of bladder cancer, the bladder cancer may grow to a certain size and have more blood vessels on the surface, which can cause the patient's tumor to rupture easily. Under the impact of urine, it is easy to cause vascular bleeding, and vascular bleeding can easily cause the patient to urinate blood, and severe cases may also be accompanied by blood clots.
