Bladder cancer is the most common tumor in the urinary system, and the data shows that the prevalence of bladder cancer currently ranks first among male genitourinary tumors in mainland China. Although the incidence of bladder cancer is relatively high, as long as it is prevented, accurately diagnosed, and accurately treated, patients can achieve relatively good treatment results and quality of life.
The main function of the bladder
The bladder is a very important organ of the human body, equivalent to the size of an apple. It has two major functions, urinary storage function and urination function.
What are the symptoms of bladder cancer?
Symptom 1: intermittent, painless, gross hematuria. The color of the patient's urine is like blood. Because the surface of the tumor is very fragile, there are many new blood vessels, as soon as the blood vessels are broken, the blood flows into the bladder and is excreted with urine, so it is called hematuria. The whole process refers to a urination from the beginning to the end, which is hematuria. Intermittently, the blood vessels are sometimes repaired and the urine is normal.
There is a case of urine, the naked eye can not see the red, but under the microscope to see that there are red blood cells, this microscopic hematuria should also be paid attention to.
Symptom 2: urinary frequency, urgency. The nerves in the orifice area of the two ureteral openings and the inner urethra are sensitive and want to urinate when stimulated by the lesion.
Symptom 3: Low back pain. The urine received by the bladder comes from the kidneys and ureters, and if the tumor grows in the position of the ureter opening, blocking the opening of the ureter, and the urine in the kidneys cannot be discharged, it will cause increased pressure in the kidneys, hydronephrosis, and low back pain.
Symptom 4: Painful urination. In general, bladder cancer is painless, and some patients have tumors that grow very large, have ruptures on the surface, infection and inflammation, and have pain when urinating.
Can long-term hair coloring cause bladder cancer?
About 20% of patients with bladder cancer are clearly related to aromatic amines containing naphthalamine or benzidine. In a study by the Southern California Medical College in the United States, more than 900 cases of bladder cancer were caused by long-term exposure to hair dyes.
In life, we should try to avoid contact with products containing aromatic amines.
Can holding back urine often lead to bladder cancer?
There is no direct evidence of bladder cancer induced by holding urine. The function of the bladder is to store urine, and the mucosal layer has a certain barrier effect and does not absorb urine toxins. However, after the bladder is overfilled, the contraction of the bladder muscle layer becomes weaker, and the urine storage and urination function of the bladder is affected.
Will eating a lot of fructose syrup cause bladder cancer?
In mouse experiments, fructose glucose syrup is found to produce a fatty acid that promotes tumor cell growth, which may promote an increase in colon cancer cells, but no animal studies have directly shown that fructose glucose syrup increases the risk of bladder cancer.
Can eating more tomatoes prevent bladder cancer?
Tomatoes contain antioxidants that have only been found in animal studies, and they have the potential to prevent cancer. Men can eat more cauliflower, broccoli, radish, Chinese cabbage and other cruciferous vegetables, these vegetables contain indole, thioside components, can inhibit the growth of cancer cells, you can also eat more oranges, oranges, grapefruit, lemons these citrus fruits, they contain carotenoids, coumarin also have anti-cancer effects.
What are the risk factors for bladder cancer?
Smoking: The relationship with bladder cancer is relatively clear.
Occupational exposure: engaged in chemical fuel, rubber industry and other special occupations, in the production process of related products, will be exposed to some volatile aromatic amines harmful substances, and the incidence of bladder cancer is related, so in the work to try to do a good job of protection.
Urinary tract disease: parasitic disease, cystitis caused by chronic inflammation, long-term untreated, gradually causing urothelial carcinogenesis.
Family history: Immediate family members have bladder cancer patients that require high vigilance.
