The most feared symptoms of advanced lung cancer are dyspnea, hemoptysis and severe pain, as they may lead to life-threatening situation.
In the advanced stage of lung cancer, the tumor is large and overgrown, occupying a certain space in the chest, resulting in limited lung expansion. As the tumor growth presses the airways, leading to lung atelectasis, or as the tumor invades the pleura, leading to pleural effusion, the patient will suffer from symptoms such as dyspnea. In the advanced stage of lung cancer, the mucous membrane of bronchial endothelium is invaded, leading to capillary rupture and hemoptysis.
When vomiting blood occurs in the advanced stage of lung cancer, attention should be paid to the fact that the blood clot may block the respiratory tract, leading to asphyxiation and endangering the patient’s life. Patients with advanced lung cancer will experience pain, which is mainly dull or hidden pain at first, obvious at night, and then gradually deteriorates and becomes unbearable day and night. Severe pain is a dying symptom of advanced lung cancer. The pain is usually caused by the invasion of cancer cells into nerves, and the effect of drugs is poor.
It is suggested that patients should pay attention to rest, prevent colds, maintain nutrition, and may be given oxygen. At the first sign of discomfort, seek medical treatment immediately.
