Is advanced lung cancer contagious? You should know the following about the contagiousness of lung cancer

Nowadays, more and more diseases are endangering our health. If the disease is discovered in time at the early stage, it can be cured. However, people often discover cancer late, and the harm of advanced lung cancer is even greater. So, is advanced lung cancer contagious? Let's take a look at the experts' explanation below.

Influenced by lung diseases such as tuberculosis, many people think that lung cancer is an infectious disease. Tuberculosis is a disease transmitted through the respiratory tract. When the sputum of a tuberculosis patient is positive, it is called open tuberculosis. It is contagious and can cause infection in the surrounding people. However, the causes of lung cancer and tuberculosis are different. Lung cancer is a tumor symptom caused by the abnormal proliferation of local cells under the action of multiple carcinogenic factors. Lung cancer is not contagious.

Is advanced lung cancer contagious? Cancer is not contagious in general. The conditions for contagion must include a source of infection, a transmission route, and a susceptible population. Lung cancer has no source of infection, so it is not contagious. Most people think that tuberculosis is lung cancer, but they are actually different. Although they are both lung problems, lung cancer is not contagious.

Lung cancer in the late stage is not contagious, because the cancer cells discharged through sputum lack suitable living conditions and will quickly degenerate and necrotize. Even fresh sputum needs to be given various nutrients and specific conditions to grow and reproduce in vitro. It takes a lot of effort for scientists to cultivate a living cancer cell, so lung cancer is not contagious.
