How long do patients with advanced lung cancer generally live
Lung cancer is one of the malignancies with the fastest growing morbidity and mortality. The cause of lung cancer has not yet been clarified, and the main causative factors are smoking, occupational exposure, air pollution, etc.
1. Reasons
1. Smoking: Long-term heavy smoking is closely related to the occurrence of lung cancer. The most carcinogens contained in the smoke produced by tobacco combustion are nicotine, coal tar, benzopyrene and cadmium.
2. Occupational exposure: those who are exposed to uranium, radium and other radioactive substances have a high incidence of lung cancer, and those who inhale higher concentrations of dust such as asbestos, chromium, nickel, welders, and radon, beryllium, and thorium for a long time have a higher risk of lung cancer;
3. Air pollution: Air pollution is mainly sulfur dioxide, carbon monoxide, arsenic, chromium, mustard gas, soot and other harmful gases in industrial exhaust gases, which can cause pulmonary fibrosis lesions and induce lung cancer.
2. Treatment
For early-stage lung cancer, the 5-year survival rate after surgical resection can reach 60%-90%, but most patients are already in the middle and advanced stages when they are diagnosed, and comprehensive treatment can be carried out by chemotherapy, radiotherapy, targeted drug therapy, etc., to prolong the life of patients and improve their quality of life.
3. Precautions
Patients are advised to maintain a good state of mind and avoid being overly emotional or nervous so as not to affect the recovery of the condition. 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 is conducive to supplementing the nutrients needed by the body and enhancing one's own resistance.
In addition, it is necessary to exercise appropriately, such as slow walking, tai chi, etc., which can promote blood circulation and help with disease recovery. If there are obvious symptoms of discomfort during the period, it is necessary to seek medical attention in time to avoid delaying the condition.
