Can advanced lung cancer be infected

summary

My grandfather got lung cancer not long ago. He coughed and coughed up blood. He also had chest pain. Now he has been hospitalized for treatment. Can advanced lung cancer patients be infected? Let's talk about it.

Can advanced lung cancer be infected

First of all, cancer in general will not be infected, and the conditions of infection must have three: source of infection, route of transmission, susceptible population. These three conditions are indispensable, so it is generally not contagious. Most people think that tuberculosis is lung cancer. In fact, it's not the same. Although all of them are lung diseases, lung cancer is not infectious.

Secondly, due to the evaporation of sputum water, the cancer cells discharged from the sputum degenerate and die rapidly. Even if the fresh sputum is used to make the cancer cells grow and reproduce in vitro, it also needs to give a variety of nutrients and specific conditions. In order to cultivate a living cancer cell, scientists often have to go through a lot of hardships to succeed, so cancer is not contagious.

Finally, it has not been confirmed whether cancer cells will survive in contact with other people's skin and digestive tract. Even if one animal's cancer cells are embedded in another animal's tissues, it is difficult to make another animal suffer from cancer. Because animals, especially humans, have a strong rejection reaction, it is difficult for the body to accept external things, which is also one of the problems that organ transplantation is difficult to succeed. Therefore, it is generally believed that cancer is not infectious, but it should be paid due attention in life.
