Is bladder cancer contagious?

Is bladder cancer contagious? Bladder cancer is the most common malignant tumor of the urinary system and one of the top ten common tumors in the body. It can occur at any age, even in children. Its incidence rate increases with age, and the peak age is 50 to 70 years old. So, is bladder cancer contagious? Let's take a look.

Experts say that bladder cancer is not contagious and will not spread. The causes of bladder cancer are complex, with both internal genetic factors and external environmental factors. The two most obvious risk factors are smoking and occupational exposure to aromatic amine chemicals. Smoking is currently the most confirmed risk factor for bladder cancer.

Another important risk factor is related to a series of occupations or occupational exposure. It has been confirmed that aniline, diaminobenzidine, 2-naphthylamine, and 1-naphthylamine are all carcinogens of bladder cancer. People who have long-term exposure to these chemicals have an increased chance of developing bladder cancer. Bladder cancer patients caused by occupational factors account for about 25% of the total number of bladder cancer patients. Occupations related to bladder cancer include aluminum products, coal tar, asphalt, dyes, rubber, coal gasification and other industries.

Bladder urothelial carcinoma is divided into non-muscle-invasive urothelial carcinoma and muscle-invasive urothelial carcinoma. Patients with non-muscle-invasive urothelial carcinoma are mostly treated with transurethral bladder tumor resection, and bladder instillation is used after surgery to prevent recurrence. Patients with muscle-invasive urothelial carcinoma and bladder squamous cell carcinoma and adenocarcinoma are mostly treated with total cystectomy, and some patients can be treated with partial cystectomy.

Take preventive measures based on the cause of the disease. For example, it has been confirmed that among external carcinogenic factors, jobs involving dyes, rubber, leather, etc. cause bladder cancer. Smoking and taking certain drugs significantly increase the incidence of bladder cancer. This requires improving the production conditions of industries such as dyes, rubber, and leather, and promoting smoking bans and avoiding large amounts of long-term use of carcinogenic drugs.
