What are the causes of bladder cancer in the elderly

The bladder is a place where urine is stored. If bladder cancer is caused by urinary tract infection, it will pose a great threat to the patient's health. Clinically, the incidence of bladder cancer in the elderly is relatively high. Many people may not know much about the causes of bladder cancer in the elderly. Today, let the experts carefully explain the common causes of bladder cancer in the elderly.

1. Chemical carcinogens

Carcinogenic substances are dye intermediates such as β-naphthylamine, benzidine, α-naphthylamine and 4-aminobiphenyl. The latency period from contact with carcinogens to cancer is 5 to 50 years, and most cases occur in about 20 years. The above carcinogens are absorbed through the skin, respiratory tract or digestive tract, and then excreted in urine. Their metabolites act on the urothelium and cause tumors. Urine stays in the bladder for the longest time, so the incidence of bladder disease is high.

2. Abnormal endogenous tryptophan metabolism

Many bladder cancer patients have no history of obvious exposure to chemical carcinogens, which may be related to abnormal tryptophan metabolism in the body.

3. Chronic infection

Bladder tumors are associated with chronic infection and irritation.

4. Others

Cyclophosphamide can also cause bladder cancer. Other drugs such as radiation exposure can also cause cancer.

[Warm Tips]: In order to stay away from bladder cancer in the elderly, the elderly should develop good behavioral habits in their daily lives. They should drink more water and eat less spicy and irritating foods to keep the urinary tract smooth. If you unfortunately suffer from cystitis, you should also actively seek medical treatment to prevent the disease from worsening and leading to bladder cancer in the elderly.
