What are the signs of bladder cancer recurrence

There are many studies and theories on the prevention of bladder cancer, but there is still no definite basis. From an epidemiological point of view, race, geographical location, diet, occupation, working environment, age, gender, and lifestyle are all related to the occurrence of bladder cancer. So what are the signs of bladder cancer recurrence? The following is a detailed introduction.

The main symptom of bladder cancer is hematuria, especially painless hematuria, with occasional discharge of tissue fragments or blood clots. Hematuria can be microscopic or gross. Bladder cancer patients go to the hospital for hematuria, and hematuria can persist or recur. Even without any treatment, hematuria can disappear, especially gross hematuria. This situation is most likely to make patients or doctors mistakenly believe that they have been cured and give up further examinations, thus delaying the disease. If the tumor invades the bladder neck, there will be difficulty in urination and frequent urination. Tumor invasion of the ureter can cause hydronephrosis. If a lump is felt in the lower abdomen, it is a late symptom. If there is hematuria, it should be thoroughly examined. There are usually many reasons for hematuria. Cystitis, prostatitis, benign prostatic hyperplasia, urinary stones, bladder tuberculosis, and non-urinary system diseases can also cause hematuria. Tumors occurring in the kidneys, ureters, or urethra can also cause hematuria, but it is not difficult to distinguish it from other diseases through X-ray urography and cystoscopy.
According to the history of hematuria, urine exfoliated cells are usually examined for tumor cells. Urinary system B-ultrasound can determine the presence and size of the mass and whether there are enlarged lymph nodes. It can also detect whether there are tumor growth and morphological changes in the kidneys and ureters. Urinary system angiography includes intravenous urography and retrograde urography, which can understand the changes in the morphology and function of the kidneys, ureters, and bladder. Cystoscopy and urethroscopy are usually performed to confirm the diagnosis of bladder cancer. Tumor tissue is removed for pathological diagnosis and cell classification. CT or MRI scans can further confirm whether the tumor has metastasized, whether there are enlarged lymph nodes around it, and the relationship between the tumor and surrounding tissues and organs.
