What are the early symptoms of lung cancer? 4 early symptoms of lung cancer

Hoarseness. This is one of the most important early signs of lung cancer and a new discovery made by experts at home and abroad in recent years. Hoarseness can occur in pharyngitis, colds, and acute bronchitis; after thyroid surgery or pharyngeal surgery; or after improper vocalization, excessive talking, or even heavy smoking and drinking.

According to statistics, more and more people are suffering from lung cancer. Lung cancer is like a time bomb around us. If we don’t do a good job of prevention, it may occur at any time and threaten our lives. So what are the early symptoms of lung cancer?

1. Cough. Because lung cancer is a respiratory disease, there will be symptoms of cough in the early stages of lung cancer. Lung cancer has different symptoms due to its different locations and functional damage. Since tumors mostly grow on large bronchi and are highly irritating, coughing is easy to occur. However, the degree of cough varies. About 50% of patients have irritating coughs, no sputum or a little white foamy sputum. After secondary infection, the quality of sputum also changes. People with chronic coughs should be alert if they find that the nature of their cough is different from usual.

2. Coughing up blood. Usually, patients with lung cancer will have symptoms of coughing up blood during the onset period. This is special in early lung cancer cases. For example, in central lung cancer, coughing up blood often occurs in the early and middle stages of the disease. The amount of blood is not much, and the blood is bright red or mixed with foam. The reason for this phenomenon is that the surface of the tumor is rich in blood vessels. Coughing damages the surface layer, causing blood vessels to rupture. If there is occasional coughing up blood, it often occurs repeatedly or only lasts for a long period of time.

3. Fever. Fever is a symptom that leads to the escalation of lung cancer. When central lung cancer grows in the bronchus and develops to the point of semi-obstruction or complete obstruction of the lumen, obstructive pneumonia may occur. The fever is generally around 38°C and can be easily reduced by anti-inflammatory treatment. However, if the obstructive lesions are not removed, pneumonia will reappear soon, forming recurrent pneumonia.

4. Hoarseness This is one of the most important early features of lung cancer and a new discovery made by experts at home and abroad in recent years. Hoarseness can occur in pharyngitis, colds and acute bronchitis; after thyroid surgery and pharyngeal surgery; it can also occur after improper voice production, excessive talking, or even heavy smoking and drinking.

In fact, there are many early symptoms of lung cancer. After reading our introduction, everyone will have a clearer understanding. Many symptoms often occur around us, but we don’t pay attention to them, so that when we discover them, they are already in the late stage of lung cancer. Therefore, everyone must pay attention to developing good living habits to prevent the occurrence of lung cancer.
