What are the common early symptoms of lung cancer? Common symptoms of early lung cancer

The early symptoms of lung cancer are not very obvious, but during its development, some symptoms such as fever, coughing up blood, and coughing will appear. If we ignore these symptoms, it will easily lead to further development of the disease and threaten our health. Therefore, we must be alert to the early symptoms of lung cancer.

Common early symptoms of lung cancer are as follows:

cough

Cough is one of the common symptoms of early lung cancer. However, due to the prevalence of such symptoms, lung cancer is often confused with other diseases in the early stages of diagnosis. The cough caused by lung cancer is caused by the growth of tumors on the bronchial lung tissue, not by inflammation of the lungs or bronchus. Therefore, when the patient has a severe cough for 2 weeks and does not get better, a comprehensive lung examination can be performed.

Blood in sputum

Hemoptysis is usually considered a symptom of the middle and late stages of lung cancer. In fact, this phenomenon has already occurred in the early stages of lung cancer. This hemoptysis is caused by tumor inflammation and necrosis. Tumor inflammation causes capillary damage, resulting in a small amount of bleeding, and this blood is usually mixed with sputum. So the hemoptysis symptom we see appears.

fever

Fever symptoms can easily lead to confusion between lung cancer symptoms and other diseases. Fever symptoms caused by lung cancer are mostly low-grade fevers, and the patient's condition is extremely unstable. Even if the fever subsides temporarily, it will recur soon. This phenomenon is caused by the tumor blocking the bronchus and obstructing the lung lobe. Experts recommend that if this phenomenon occurs, you should go to the hospital immediately.

Chest tightness and pain

The chest tightness and pain in the early stage of lung cancer has no fixed location. Patients sometimes experience dull pain and dull pain, and the relationship between this phenomenon and breathing is uncertain. From a pathological point of view, this phenomenon is caused by cancer involving the pleura.

The common early symptoms of lung cancer are introduced here. The early symptoms of lung cancer are not very obvious and are often easily ignored by people. Therefore, we should pay more attention to and understand the knowledge about lung cancer in our daily lives so as to better control the disease and achieve the goal of timely treatment of lung cancer.
