Is bladder cancer contagious?

Bladder cancer is the most common malignant tumor of the urinary system, and its incidence rate ranks first among malignant tumors of the urinary system. The cause of the disease is still unclear, but it is generally believed to be related to frequent contact with carcinogens such as naphthylamine and benzidine. Dyes, rubber, plastic products, paints, detergents, etc. commonly seen in daily life also have potential carcinogenic risks. So is bladder cancer contagious?

Bladder cancer is not contagious. Cancer is not transmitted from one person to another like other germs. Even if sexual intercourse occurs, it cannot be transmitted to another person through sexual contact. The reason is simple. Cancer is not an infectious disease. It cannot transmit cancer-causing genes to other people's bodies through any means to cause cancer. Even if cancer cells are implanted into other people's bodies, they cannot survive. Because to oneself, other people's cancer cells are a kind of foreign body, and the body can kill other people's cancer cells through its strong immune rejection ability.
It is not contagious. Cancer cells in the patient's body are a group of abnormal cells that have lost control and grow in an invasive manner. They not only destroy adjacent normal tissues and organs, but can also spread to all parts of the body through the lymphatic system and blood circulation, absorbing a large amount of nutrients, growing and proliferating rapidly, leading to systemic failure of the patient and even death. Although cancer cells can spread or metastasize everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses.
