Is bladder cancer an infectious disease?

We have a lot of doubts about the occurrence of bladder cancer, because the complication rate of bladder cancer is very high, and once a disease like bladder cancer occurs, we face a lot of harm. So is bladder cancer an infectious disease? What is the cause of a disease like bladder cancer?

What are the causes of bladder cancer?

1. Workers who are exposed to aromatic substances for a long time. This is one of the causes of bladder cancer. For example, workers who work with dyes, leather, rubber, and paint may have a high incidence of bladder tumors.

2. Smoking. It is also a cause that increases the incidence of bladder cancer. Recent studies have shown that smokers increase the metabolism of tryptophan, a carcinogen, in their urine by 50%. When smoking stops, tryptophan levels return to normal. Smoking is a common cause of bladder cancer.

3. 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 β-glucuronidase.

4. Long-term local irritation of the bladder mucosa. Long-term local irritation of the bladder wall, such as long-term chronic infection, long-term irritation of bladder stones and urinary tract obstruction, may be factors that induce cancer. Glandular cystitis and mucosal leukoplakia are considered precancerous lesions that can induce cancer.

5. Drugs: Taking large amounts of phenacetin drugs has been proven to cause bladder cancer.

6. Parasitic disease: If it occurs in the bladder, it can also induce bladder cancer.

It can be seen that bladder cancer is not contagious. Through the above explanation, do you have a certain understanding of the causes of diseases such as bladder cancer? In fact, there are many tragedies caused by diseases such as bladder cancer. We must actively prevent diseases such as bladder cancer!
