What are the early symptoms of primary lung cancer?

Smoking is the main cause of lung cancer, and 87% of lung cancer deaths are related to smoking. Lung cancer has become the main killer of human survival. So far, the effective treatment of lung cancer has limited effect and is far from achieving the goal of complete cure. Early detection and early treatment are the most effective ways to improve the healing effect of lung cancer.

So what are the early symptoms of lung cancer?

Fever: Long-term low-grade fever is one of the early symptoms of lung cancer. After the tumor blocks the bronchus, there are often different degrees of obstruction of the lung lobe. Mild cases only have a low fever, and severe cases only have a high fever. It can be temporarily improved after drug treatment, but it will relapse soon.

Cough: Cough is a typical symptom of lung cancer, and the early stage of the disease is very similar to a cold. Because lung cancer grows on bronchial lung tissue, it usually causes respiratory irritation and irritating cough.

Blood stasis: When coughing, it is often accompanied by varying degrees of sputum. In any case, there will be congested sputum. Tumor inflammation causes necrosis, and a small amount of bleeding occurs when capillaries rupture. It is often mixed with sputum, intermittent or intermittent. Many lung cancer patients receive blood stasis treatment.

Chest pain: The clinical manifestation of chest pain is very common, and it is more common in patients with early lung cancer. The chest pain in the early stage of lung cancer is mild, mainly manifested as dull pain, dull pain, not necessarily in where, and the relationship with breathing is uncertain. If the pain persists, it means that the cancer may involve the pleura.

Hoarseness: Hoarseness is often accompanied by coughing symptoms and is also one of the common early symptoms of lung cancer. Lung cancer metastasis compresses the laryngeal nerve, causing hoarseness of the vocal cords. Since lung cancer metastasis can occur in the early stage and the county metastasis sometimes grows faster than the primary tumor, the clinical manifestations of metastasis can appear before the primary lesion.
