What are the symptoms of bladder tumors

Bladder tumors are a relatively common type of urinary tumor. The cause of the disease is still unclear, but surveys show that people who smoke for a long time and have occupational exposure to aromatic amines are more likely to develop bladder tumors. The best time to treat this disease is in the early stages, so it is important to understand the symptoms of bladder tumors. So what are the symptoms of bladder tumors?

About 75% to 78% of patients with bladder tumor symptoms suffer from hematuria, which is mostly painless or intermittent. Hematuria is mostly caused by tumor rupture and bleeding. The hematuria can be more or less. When it is more, it can be seen with the naked eye. When it is less, red blood cells in the urine can only be seen under a microscope. Hematuria of bladder cancer is generally visible throughout the process, that is, the urine is bloody during the entire urination process, and the urine color often darkens when urination is about to end; 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 tumors has two characteristics:

1. Painless: When hematuria occurs, the patient does not feel any pain or other discomfort symptoms, which is called painless hematuria in medicine. 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.

2. Intermittent: Hematuria occurs intermittently and can stop or improve on its own. If hematuria only occurs once or twice, and the interval between two episodes of hematuria can be several days, months, or even half a year, and the patient does not pay attention to it, thinking that it is caused by fatigue or a cold, and that it is not a big problem, patients often mistakenly believe that hematuria has healed on its own and no further diagnosis and treatment is needed, thus losing the best time for treatment.

Painless hematuria is the most important sign of bladder tumors. Almost all bladder cancer patients will have this signal first. If you can catch this signal and go to the cancer hospital for examination in time, you can achieve early detection and early treatment, and achieve better results. The diagnosis of bladder tumors mainly relies on cystoscopy, which can directly see the size, shape, location, number and range of the tumor. The diagnostic accuracy of specialists can reach more than 90%. Looking for cancer cells in urine is also one of the diagnostic methods, and its positive rate can reach 80%. In addition, B-ultrasound examination can help understand the degree of tumor infiltration, and CT also has a certain effect on determining the stage of the tumor.

Bladder tumors are divided into benign and malignant. Regardless of whether it is a malignant tumor or not, patients should go to the hospital for treatment as soon as possible, rely on medical diagnosis to distinguish the cause of cancer and the stage of onset, and achieve early detection, early diagnosis, and early treatment. Bladder cancer is not very scary, and an optimistic and positive mood is also the key to recovery.
