Can lung cancer be transmitted when kissing? It is better to know these common knowledge about lung cancer as early as possible

Lung cancer is very harmful, so our awareness of its prevention has gradually increased due to its "renowned" reputation. Some people believe that lung diseases are exhaled through the respiratory tract and can be transmitted during kissing, so they panic. So, can lung cancer be transmitted during kissing? Let's take a look at the experts' answer.

Can lung cancer be transmitted through kissing? Experts can tell you for sure that lung cancer is not transmitted through kissing. Below, we find out the reasons why lung cancer is not transmitted:

Experts point out that a disease is contagious under certain conditions, such as the presence of a source of infection, a transmission route, and a susceptible population. These conditions must exist to prevent it from being transmitted to others. Most people think that tuberculosis is lung cancer, but in fact there is a difference, because lung cancer is not contagious.

Clinical data prove that cancer patients themselves are not the source of infection. 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 transfer to all parts of the body through the lymphatic system and blood circulation, and absorb a large amount of nutrients, grow and proliferate rapidly, leading to systemic failure of the patient and even death. Although cancer cells can spread or transfer everywhere in the patient's body, they will not be transmitted from one person to another like bacteria and viruses. To oneself, other people's cancer cells are a kind of foreign body, and the body destroys the cancer cells through its powerful immune rejection ability.

Lung cancer is not tuberculosis as we know it. Tuberculosis is a respiratory infectious disease, while lung cancer is caused by the abnormality of local cells under the action of different carcinogenic factors. It is mainly because the normal cell form is lost, so people get sick. Can lung cancer be contagious when kissing? We can rest assured that lung cancer is not contagious. Cancer cells will quickly degenerate or necrotize, and once the cancer cells have no conditions for growth and reproduction.

Therefore, other people's cancer cells cannot survive in your own body. Can lung cancer be transmitted when kissing? From the perspective of infectious diseases, lung cancer is not contagious. However, experts remind everyone that lung cancer is not contagious, but it can spread. Lung cancer can not only spread locally, but also spread to nearby tissues, such as the external space of the lungs (costal diaphragm), the pericardium, and may also spread to more distant parts, such as lymph nodes, liver, bones, brain and the other half of the lungs.

Lung cancer can also spread to the adrenal glands, which are located above the kidneys and produce hormones, or to the nearby spinal cord and vertebrae.

Therefore, cancer treatment experts remind that if you feel that you have early symptoms of lung cancer, you should go to a regular hospital for examination and treatment as soon as possible to achieve early detection and early treatment to avoid delaying the disease.
