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

Lung cancer is like a time bomb. If we don’t treat it in time, it may explode at any time, and the result of the explosion is death. In fact, lung cancer is also very easy to treat in the early stage, but many people always delay it again and again, and the result is very serious. Let’s first look at the early symptoms of lung cancer.

Experts explain to you who are the high-risk groups for lung cancer? First of all, the high-risk groups for lung cancer are people over 40 years old, who usually smoke more than a pack a day and have smoked for more than 20 years, especially men; if the following conditions occur in this group of people, they should be highly vigilant:

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 where the lumen is semi-obstructed or completely obstructed, 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.

Some of the symptoms described above often occur in our lives. I believe everyone has experienced them, but just didn’t pay attention. These are the early symptoms of lung cancer. After reading them, you should be clearer. Here we suggest that if you have similar symptoms, don’t take it lightly.
