Bladder tumors constitute about 4% of all neoplasms, second in frequency only to tumors of the stomach, esophagus, lung and larynx. According to world statistics, the frequency of this disease is increasing.
Bladder cancer is the fourth in frequency in men and the eighth - in women, which indicates the urgency of this problem. Bladder tumors are significantly more common in men than in women (4:1). Most of the bladder in men explains the more frequent exposure to carcinogenic substances and more prolonged delay in the urine in the bladder.
Neoplasm of the bladder is found mostly in persons over 50 years. Bladder tumors in children are rare - 60 times rarer than in adults, more frequently in boys. Tumors may be located in all parts of the bladder, but the most frequent localization of-urocystic Triangle and surrounding areas.
Currently, chemical theory of the origin of bladder tumors is the most widespread. Ill bladder contains more carcinogens than the bladder of healthy person. These carcinogens include the decay products of certain amino acids.
Main symptom of bladder cancer is urinating blood, in other words hematuria. Blood can be released, even if you feel fine. But at the same time, this symptom can announce that the tumor is already in the final stage. During germination of the tumor in the bladder wall, there is pain when urinating. If the tumor is running, the pain is constant. Bladder tumor can affect the lymph and blood vessels. Cystoscopy is the main way to diagnose bladder cancer. Examination of the bladder is made by using a thin metal tube that is inserted through the urethra.
Treatment is carried out by surgical intervention. There can be used a radiation therapy or chemotherapy. If the tumor is small, it can be removed using endoscopic techniques.
