Is lung cancer contagious? Introducing common knowledge about key lung cancer diseases

Many lung cancer patients, their families, and people around them are very concerned about one issue, that is, whether lung cancer is contagious. Indeed, this issue needs to be clarified. Patients and their families can rest assured that lung cancer is not a contagious disease and will not be spread through daily contact and other behaviors. Let's take a look at the specific reasons.

Can lung cancer be transmitted to other people?

Let's take a look at what infection is and the specific process of infection. The so-called infection refers to the transmission of bacteria and viruses through certain channels. The definition of infection is that a disease is transmitted from one person to another through a certain channel. Infection must meet three conditions: the source of infection, the route of transmission and the susceptible population. None of these three aspects can be missing. Lung cancer cells are not transmitted from one person to another like bacteria and viruses. Cancer cells are a foreign body. The body can kill other people's cancer cells through its powerful immune rejection ability, so other people's cancer cells will not be transmitted to its own body. Moreover, many clinical data show that cancer patients themselves are not the source of infection. Therefore, lung cancer is not contagious.

Cancer cells of lung cancer patients cannot be transferred to other people, but they can spread within the patient. Cancer cells, including lung cancer cells, are a group of out-of-control abnormal cells that can be transferred to all parts of the body through the patient's lymphatic system and blood circulation. While absorbing a large amount of nutrients, they destroy the patient's normal tissues and organs, leading to systemic failure and even death. Many data show that keeping the patient happy physically and mentally is the best medicine to improve anti-cancer. Patients should have a good attitude and be optimistic about life, so that they will have the confidence and courage to defeat the disease.

Therefore, the answer to the question of whether lung cancer is contagious is that it is not contagious. Patients should rest assured and not have an inferiority complex. After lung cancer is diagnosed, it is necessary to receive timely treatment to fight a time war with cancer cells and control them as soon as possible before they spread.

Cancer is not contagious, but many patients have an inferiority complex, and many people look at cancer patients with tinted glasses. These are all wrong. Cancer patients are also human beings. If the disease is under control, they will have the same behaviors and needs as normal people.
