Is lung cancer hereditary? If you want to know the hereditary nature of lung cancer, please read these points

In the past, everyone believed that "lung disease" was contagious, and this "lung disease" was pulmonary tuberculosis. Patients with pulmonary tuberculosis are called open pulmonary tuberculosis when their sputum is positive for bacteria, which is contagious. Therefore, if you encounter patients with coughs, sputum, or blood in their sputum, you should pay attention to disease prevention.

If you think of lung cancer as a contagious disease, then you are really wronged. Experts point out that this disease is not actually hereditary. The reason why many people think that lung cancer is hereditary is because they confuse lung cancer with tuberculosis. As long as we understand the differences between these two diseases, we can better cure lung cancer.

Is lung cancer hereditary?

In the past, everyone believed that "lung disease" was contagious, and this "lung disease" was pulmonary tuberculosis. Patients with pulmonary tuberculosis are called open pulmonary tuberculosis when their sputum is positive for bacteria, which is contagious. Therefore, patients with cough, sputum, and blood in their sputum should pay attention to disease prevention. Pulmonary tuberculosis is a disease transmitted through the respiratory tract, while lung cancer is different from pulmonary tuberculosis. Lung cancer is a malignant tumor caused by the abnormal proliferation of local cells under the action of multiple different carcinogenic factors, and the loss of normal cell morphology and dynamics.

In animal experiments, tumor-bearing animals were kept together with non-tumor-bearing animals for a long time, and no direct transmission was found. In some families, multiple people have lung cancer or other tumors one after another. This may be related to the fact that family members share the same genes and they may be in the same carcinogenic environment, such as smoking, exposure to radioactive substances, etc., so family members can develop malignant tumors one after another.

Lung cancer is not caused by bacteria or other microorganisms, and there is no direct pathogen, so it is not contagious and does not require hospitalization and isolation. Lung cancer is caused by excessive proliferation of bronchial or alveolar epithelial cells, followed by mutations, and finally cancer. In some cases, lung cancer has a certain family clustering. Unlike genetic diseases, lung cancer does not have dominant or non-dominant inheritance patterns. Therefore, the "hereditary" nature of lung cancer is only a potential possibility, not a necessity. Therefore, even if someone in the family has had lung cancer, there is no need for others to be overly nervous.

So lung cancer is not contagious. So far, it can be said with certainty that cancer is not contagious. In simple terms, contagion means that a disease is transmitted from one person to another through some means. Contagion must meet three conditions: the source of infection, the route of transmission, and the susceptible population. Clinical data prove that cancer patients themselves are not the source of infection.

Finally, experts pointed out that during the treatment period, lung cancer patients should not only feel whether the symptoms of lung cancer are getting worse, but also observe with their own eyes to see whether their physical condition is improving. If the condition of lung cancer is getting worse while insisting on taking medication, it is best for patients to discuss with their doctor and switch to a more effective treatment plan.
