What are the symptoms of bladder cancer in the early stages?

Bladder cancer is the most common malignant tumor in the urinary system. Its incidence rate is high in my country, and it is more common in patients over 50 years old, and more common in men than in women. Whether bladder cancer can be diagnosed early is crucial to the patient's prognosis. In order to detect bladder cancer in its early stages, the most important thing is to understand the early symptoms of bladder cancer. So what are the symptoms of bladder cancer in its early stages?

Bladder cancer mostly occurs in the bladder mucosal epithelium, grows quickly, and is prone to ulceration and bleeding on the surface. Therefore, the most common symptom of bladder cancer is hematuria that can be seen with the naked eye without any feeling. This is a unique "abnormal urination signal" of bladder cancer, which occurs in almost every bladder cancer patient, and about 85% of bladder cancer patients seek medical treatment for this reason. Hematuria caused by bladder cancer is generally visible throughout the entire process, that is, the urine is bloody during the entire urination process, and the urine color often deepens at the end of urination; it can also be that the urine starts with blood and then becomes clear, or the urine starts with clear and then becomes hematuria. Compared with hematuria caused by other diseases, hematuria caused by bladder cancer has two characteristics:

The first is painlessness, that is, when hematuria occurs, the patient does not have any pain or other discomfort symptoms, which is medically called painless hematuria. This is different from the pain in the kidneys and ureters caused by stones, and different from the frequent urination, urgent urination, and painful urination caused by cystitis. However, if the tumor is necrotic, ulcerated, or infected, bladder irritation symptoms such as frequent urination, urgent urination, and painful urination may occur;

The second is intermittent, that is, hematuria occurs intermittently, can stop or reduce on its own, and the interval between two hematurias can be several days or months, or even half a year, which can easily create the illusion that hematuria has been cured and improved, and thus fail to seek medical examination in time. Therefore, patients with painless hematuria or patients with long-term incurable "cystitis" should go to the hospital in time to undergo urine exfoliated cell examination.

A small number of bladder cancer patients may not have macroscopic hematuria, but only show excessive red blood cells when examining urine under a microscope, i.e. microscopic hematuria. In addition, patients may also have microscopic hematuria after macroscopic hematuria stops on its own. Therefore, patients with microscopic hematuria or abnormal urine routine examination should also undergo urine exfoliated cell examination. Tomjanovich had a bladder infection one month before he was diagnosed with bladder cancer, which was mainly manifested by symptoms such as frequent urination, urgency, and pain when urinating, as well as microscopic hematuria.

The above is some knowledge about bladder cancer.
