1.What is the work of the bladder? The bladder is a urine storage organ in the body, its main job is to store the urine produced by the kidneys, and when the urine in it accumulates to a certain level, it will be conditioned to fire and transmit information to achieve urination. The treating doctor said that “the bladder is like a sewage reservoir in the sewer pipe, when the sewage is stored to a certain amount, it is necessary to open the gate to discharge.” 2.What are the factors that trigger “bladder cancer”? ”Bladder cancer is a malignant tumor that occurs on the mucosa of the bladder, which is the most common malignant tumor of the urinary system. The bladder is a reservoir in the urinary tract, and when the stored urine contains too many toxins over a long period of time, it can irritate the mucous membrane of the tissue and become a tumor. The occurrence of bladder cancer is related to a combination of family genetics, individual differences, life, eating habits, occupational characteristics and other factors, while “smoking” is the primary risk factor for “bladder cancer”, and men’s bladder is more likely to be “cancerous” than women’s. “The incidence of bladder cancer in men is about twice that of women. 50%-60% of bladder cancer patients have a history of smoking, and the prevalence rate of smoking is 4-6 times higher than that of the general population, and the incidence rate will increase as the time spent smoking increases. The second risk factor for bladder cancer is long-term contact with chemicals, such as people engaged in manufacturing industries such as printing and dyeing, petrochemicals, leather, or long-term hair dyeing, contact with dyes, paints, rubber and other chemical elements, most of these contacts contain more carcinogens such as benzene, ammonia, naphthalene, etc. These factors can easily make the bladder be “cancerous”. These factors can easily cause the bladder to be “cancerous”. 3.Clinical manifestations of bladder cancer? The clinical manifestation of bladder cancer is mainly painless carnal hematuria, and some patients will have symptoms such as urinary frequency and urinary urgency and pain. Remind the public that the general phenomenon of hematuria may be a simple urinary tract infection, but it should be taken seriously and should go to the hospital for urinary routine and ultrasound examination in time. 4.The “danger” index and treatment level of bladder cancer. If liver cancer, lung cancer and pancreatic cancer are life-ending demons, bladder cancer may be a relatively weak monster in human cancer. Bladder cancer is relatively slow to develop and most of the cases are relatively mild. Early detection and scientific treatment can prolong the life span of patients by more than 10-20 years, however, there are very few bladder cancers that are extremely malignant, which are generally advanced and the cancer cells have metastasized to other organs. In the treatment of bladder cancer, the treatment plan is selected according to the patient’s specific physical condition, tumor stage and grading, growth pattern and number. For example, the patient’s condition determines whether to undergo surgery or radiotherapy, and the surgical treatment plan will be based on the patient’s actual condition, including bladder preservation or total bladder removal. At present, our hospital adopts transurethral electrodesiccation of bladder tumor, which is a minimally invasive surgical procedure without incision, using laser, for bladder preservation treatment. In addition, for problems that cannot be solved by electrodesiccation, partial or total bladder resection will be performed, and after total resection, the patient will undergo urinary diversion. Currently, of course, some patients with the right conditions can receive an in situ neobladder, which greatly improves the patient’s quality of life after the cure. 5, “bladder” how to keep you from being “cancer”. A healthy lifestyle is the source of a healthy body. In order to resist the attack of bladder cancer, we must be clear about the enemy’s way, first of all, “please don’t smoke” is always on your lips, and public places should be completely smoke-free to reduce the damage of second-hand smoke. Secondly, people in bladder cancer high-risk industries who have long-term exposure to chemicals should also do their best to protect themselves and reduce the amount of harmful substances inhaled. Once again, you should try to let boiling water stand for a while before drinking it, so that the “arsenic” and “chlorine” in the water can be evaporated. You should know your family history, go to the hospital regularly for routine medical checkups, and pay attention to recurrent urinary tract infections when they occur, and seek medical attention in a timely manner.
