Detailed introduction: Is laryngeal cancer contagious?

Generally speaking, viruses are contagious, but the infectivity of different viruses varies. After viral infection, only 1% of people develop clinical symptoms, while the majority of people do not develop symptoms and are in a latent infection state. Whether or not a person develops symptoms after viral infection is closely related to the body's defense function. If the body's defense function is strong, even if there is a viral infection, the person may not develop the disease for the rest of his life.

Foreign medical scientists have also demonstrated that laryngeal cancer is contagious. Through long-term observation of patients in cancer sanatoriums, they found that cancer patients with ulcers and cancer patients without ulcers who stayed together for a long time never infected each other.

On the other hand, there are countless cancer patients treated by doctors, and the cancer incidence rate of doctors is no higher than that of ordinary people. It is a common fact that animals with cancer and healthy animals live in the same room, and no direct infection has been found.

In hospitals, patients with different types of cancer have lived in the same room for a long time, and for many years, no one has ever been found to have infected each other. Medical staff have long-term contact with cancer patients, and have not found that their cancer incidence rate is higher than that of the general population.

After reading the above introduction, I believe that patients with laryngeal cancer can rest assured that laryngeal cancer is not contagious, so don't be afraid of injuring your family and friends. In normal times, we may lack medical knowledge, so in normal times, we should learn more about this knowledge to be prepared.
