What causes bladder cancer? Can regular urination prevent bladder cancer?

Bladder cancer refers to a malignant tumor that occurs on the bladder mucosa. It is the most common malignant tumor of the urinary system and one of the top ten common tumors in the body. It ranks first in the incidence of urogenital tumors in my country, and second in the West after prostate cancer. In 2012, the incidence of bladder cancer in the National Cancer Registry was 6.61/100,000, ranking ninth in the incidence of malignant tumors. Bladder cancer can occur at any age, even in children. Its incidence increases with age, with a peak age of 50 to 70 years old. The incidence of bladder cancer in men is 3 to 4 times that of women.

What are the causes of bladder cancer?

First, smoking is also a cause of increasing the incidence of bladder tumors. Recent studies have shown that the metabolism of the carcinogenic substance tryptophan in smokers' urine increases by 50%. When smoking stops, tryptophan levels gradually return to normal. It is also found that vitamin C can reduce the activity of tryptophan in both smokers and non-smokers.

Second, if parasitic diseases occur in the bladder, they can also induce bladder cancer.

Third, workers who are exposed to aromatics for a long time, such as dyes, leather, rubber, and painters, may have a higher incidence of bladder tumors. Statistics have shown that the incidence rate among workers exposed to aniline is 30 times higher than that of the general population. Benzidine, 4,4-diaminobisphenyl, 4-aminobisphenyl, etc. are all considered to be relatively certain foreign chemical carcinogens. After these substances enter the body, they are metabolized by the liver and excreted into the bladder with urine, and then decomposed into α-aminonaphthoic acid by glucuronidase, making it carcinogenic and causing occupational bladder cancer. However, the incubation time of cancer is relatively long, up to about 20 years.

4. Abnormal tryptophan metabolism in the body. Abnormal tryptophan metabolism can produce some metabolites, such as 3-hydroxy-2-aminoacetophenone and 3-hydroxy-o-aminobenzoic acid, which can directly affect the synthesis of RNA and DNA in cells. These metabolites are excreted into the bladder through the liver and have carcinogenic effects after being acted on by glucuronidase. The concentration of these carcinogens in the urine of bladder tumor patients is often significantly increased. The following introduces how to relieve bladder cancer pain through massage.

Urinating once an hour may reduce bladder cancer risk

There is no set rule for when and how often a person should urinate. The usual practice is to go to the toilet when the bladder is full. However, there is now a saying that urinating every hour, whether you feel like urinating or not, can reduce the risk of bladder cancer.

The possibility of bladder cancer is directly proportional to the time urine stays in the bladder. It turns out that there is a chemical substance in urine that can cause cancer. This substance can damage the muscle fibers of the bladder, destroy its cells, and promote its cancer. Researchers compared the urine discharged every hour with the urine discharged every 2-3 hours. The latter contains a lot of carcinogens, so it is recommended to urinate once an hour to effectively reduce the risk of bladder cancer.
