Three good habits should be developed to prevent bladder cancer 1. Quit smoking. Smoking is the most certain risk factor for bladder cancer, 30% to 50% of bladder cancer is caused by smoking, and smoking can increase the risk rate of bladder cancer by 2 to 6 times. The toxic effects of cigarettes on the human body are not only limited to the lungs, but after gas exchange through the lungs, harmful substances such as nicotine will enter the bloodstream and participate in the whole body metabolism with blood circulation, and finally filtered through the kidneys, the urine with harmful substances such as nicotine will gather in the bladder. It can be said that the bladder is the concentration of cigarette toxins, therefore, it is urgent to quit smoking.
2.Avoid long-term exposure to carcinogenic substances. In addition to smoking, another important risk factor for bladder cancer is related to a series of occupations or occupational exposure. It has been confirmed that aniline, diaminobiphenyl, 2-naphthylamine, and 1-naphthylamine are all carcinogens of bladder cancer, and long-term exposure to such chemicals increases the probability of bladder cancer, and occupational factors account for about 25% of all bladder cancer patients. Occupations associated with bladder cancer include industries such as aluminum products, coal tar, asphalt, dyes, rubber, and coal gasification. People struggling in these industries most urgently need to take precautionary measures, eat more cancer-fighting foods, exercise more to improve immunity, and have regular health checkups.
3. Try not to hold urine. Holding urine is medically called compulsory urine retention. Urine is the product of kidney metabolism and contains many wastes and various toxic substances produced by human metabolism. The bad thing about holding urine in the bladder is that the more urine that accumulates, the more urine containing bacteria and toxic substances cannot be discharged in time, which can easily cause cystitis, urethritis and other diseases. The greater harm of holding urine is that it is easy to develop bladder cancer. The possibility of bladder cancer is directly proportional to the time urine stays in the bladder. There is a cancer-causing chemical in urine that can attack the mucous membrane of the bladder and promote cancer, and holding urine will prolong the effect of the cancer-causing substance on the bladder.
Studies have reported that people who hold urine are three to five times more likely to develop bladder cancer than the average person. In order to prevent and control the high incidence of bladder cancer, you should drink more water and urinate more often. Of course, besides the above factors that lead to the highest chance of bladder cancer, there are also other reasons, such as the decline of androgen level when men enter old age, which also easily induces bladder cancer, so older men should pay more attention to health care.
To seek medical attention as soon as possible, hematuria is the earliest symptom of bladder cancer. The most important characteristic of hematuria is that it is painless and occurs for no reason. Some people have hematuria because of strenuous exercise or too much strain, while others have it caused by stones, which will be combined with abdominal pain, back pain, nausea, vomiting, etc. However, in bladder cancer, hematuria is mostly painless hematuria that occurs for no reason. If you ignore it at an early stage, you may eventually have difficulty urinating, painful urination, or even inability to urinate. There are two types of hematuria, one is visual hematuria and the other is microscopic hematuria. Microscopic hematuria refers to urine with blood color that can be seen by the eyes, while microscopic hematuria refers to urine with red blood cells that can be found under a microscope.
Compared with the hematuria caused by other diseases, the hematuria of bladder cancer has two characteristics: one is painless, that is, when hematuria occurs, the patient does not have any pain and other discomfort symptoms, which is medically called painless hematuria. This is different from the pain of kidney and ureter when stones have hematuria, and it is also different from the hematuria caused by cystitis which is accompanied by frequent, urgent and painful urination. However, if the cancer is necrotic, ulcerated and co-infected, bladder irritation symptoms such as urinary frequency, urinary urgency and urinary pain may occur. Secondly, it is intermittent, that is, hematuria appears intermittently and can be stopped or reduced by itself.
Ultrasound examination of the urinary system is a basic urological examination and one of the first choice for patients with hematuria, while the most accurate examination for diagnosing bladder cancer is cystoscopy. In the past, the “hard-scope” instrument was painful and intimidating to patients. Painless examination under anesthesia can be chosen to reduce the patient’s psychological burden and reduce the rate of misdiagnosis and leakage of the disease.
Some drugs can cause progressive renal failure or chronic renal failure, which is insidious in its onset and slow in its progression, but the clinical consequences are very serious. Gentian and liver pills are known to be “really effective in defeating fire” by patients who take them regularly. Another most important factor is that many patients believe that Chinese medicine has less toxic side effects compared to western medicine. However, long-term use of Gentian and Liver Pills can lead to bladder cancer due to the presence of a Chinese herb called Guanmutong, which contains aristolochic acid.
It is worth noting that long-term small doses of aristolochic acid-containing drugs can not only lead to chronic kidney failure, but may also cause cancer, especially cancers of the urinary system and digestive system, such as bladder cancer, renal pelvis and ureteral cancer.
