There are several causes of bladder cancer

Bladder cancer is a common disease, and the causes of bladder cancer are diverse. However, many people do not know much about the causes of bladder cancer. So, what are the specific causes of bladder cancer ? Let's ask an expert to give you a detailed introduction to the causes of bladder cancer.

1. Smoking is the cause of bladder cancer

It is also a reason for increasing the incidence of bladder tumors. Recent studies have shown that smokers increase the metabolism of the carcinogenic substance tryptophan in their urine by 50%. When smoking stops, tryptophan levels return to normal.

2. Abnormal tryptophan metabolism in the body

Abnormal metabolism of tryptophan 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.

3. Long-term local irritation of the bladder mucosa

Chronic local irritation of the bladder wall, such as chronic infection, bladder stones and urinary tract obstruction, may be the cause of bladder cancer. Cystitis glandularis and leukoplakia are considered to be precancerous lesions that can induce cancer.

4. Workers who are exposed to aromatic substances for a long time

Causes of bladder cancer, such as dyes, leather, rubber, and painters, may have a high incidence of bladder tumors.

5. Medication

Taking large amounts of phenacetin drugs has been proven to cause bladder cancer, so this is also one of the causes of bladder cancer.

6. Parasitic diseases

If it occurs in the bladder, it can also induce bladder cancer.
