How long can patients with advanced lung cancer generally live?

Lung cancer is one of the malignant tumors with the fastest growing morbidity and mortality. The cause of lung cancer has not yet been clearly identified, and the main causative factors include smoking, occupational exposure, and air pollution.

1. Reasons

1. Smoking: Long-term heavy smoking is closely related to the occurrence of lung cancer. The smoke produced when tobacco is burned contains the most carcinogenic substances such as nicotine, coal tar, benzopyrene and cadmium;

2. Occupational exposure: People who are exposed to radioactive substances such as uranium and radium have a high incidence of lung cancer. People who work with asbestos, chromium, nickel, welders, and those who inhale high concentrations of dust such as radon, beryllium, and thorium for a long time have a higher risk of lung cancer.

3. Air pollution: Air pollution mainly includes sulfur dioxide, carbon monoxide, arsenic, chromium, mustard gas, coal smoke and other harmful gases in industrial waste gas, which can cause pulmonary fibrosis and induce lung cancer.

II. Treatment

For early lung cancer, the 5-year survival rate after surgical resection can reach 60%-90%, but most patients are already in the middle and late stages when diagnosed. At this time, comprehensive treatments such as chemotherapy, radiotherapy, and targeted drug therapy can be used to prolong the patient's life and improve their quality of life.

3. Notes

Patients are advised to maintain a good attitude and avoid being too excited or nervous, so as not to affect recovery. At the same time, pay attention to a healthy diet, eat more fresh fruits and vegetables and foods rich in high-quality protein, such as apples, bananas, milk, eggs, etc., which are beneficial to supplement the nutrients needed by the body and enhance its own resistance. In addition, appropriate exercise, such as slow walking and Tai Chi, can promote blood circulation and also help recovery from the disease. If obvious discomfort symptoms occur during the period, it is necessary to seek medical treatment in time to avoid delaying the condition.
