Is lung cancer hereditary? It is somewhat hereditary

Lung cancer has a certain genetic susceptibility. If other relatives in the family have lung cancer, then the individual's chance of developing lung cancer will be higher than that of ordinary people. For such people, in order to avoid the occurrence of lung cancer to the greatest extent, they must do a good job of prevention, quit smoking in time, pay attention to developing good eating and living habits, and go to the hospital for regular screening.

Lung cancer is one of the most common cancers in my country. After being diagnosed with lung cancer, patients will experience symptoms such as coughing, hemoptysis, chest pain, fever, etc., which can lead to death in severe cases. After being diagnosed with lung cancer, many patients will be very worried about whether their next generation will inherit lung cancer. So, is lung cancer hereditary?
1. Is lung cancer hereditary? Lung cancer does have a certain genetic susceptibility, that is, if there are other relatives with lung cancer, then the individual's chance of developing lung cancer will also be relatively high. Therefore, for people with lung cancer in their family, they should pay more attention to preventive measures, avoid smoking, eat a healthy diet, develop good work and rest habits, and exercise regularly. Also, pay attention to regular CT screening of the lungs at the hospital, which can prevent the occurrence of lung cancer to the greatest extent.
2. Some of the causes of lung cancer
1. Smoking <br/>Smoking is a high-risk factor for lung cancer. Tobacco contains a variety of chemical substances, among which nitrosamines and poly-chain aromatic hydrocarbons are carcinogenic. They can damage bronchial epithelial cells, leading to the activation of oncogenes and the inactivation of tumor suppressor genes, eventually leading to cancer.
2. Occupation and environment <br/>Occupation also has an important impact on the occurrence of lung cancer. Some specific occupational environments, such as arsenic, mustard gas, asbestos, aluminum byproducts, chromium compounds, etc., can increase the incidence of lung cancer. Long-term exposure to toxic chemicals and living in a polluted environment can also cause lung cancer. The lungs are very sensitive to radiation, and ionizing radiation can also cause lung cancer.
3. Previous chronic lung infection <br/>Patients with diseases such as tuberculosis and bronchiectasis may have bronchial epithelial cells metaplasticized into squamous epithelium during chronic infection, leading to cancer. However, this situation is relatively rare.
4. Air pollution <br/>The incidence of lung cancer is higher in some developed countries. This is mainly because the industries and transportation in these countries are relatively developed. Oil, coal, etc. can produce harmful substances after burning, which pollutes the atmosphere and increases the incidence of lung cancer.
