What are the signs of early lung cancer? Know the symptoms of early lung cancer

Lung cancer is also a type of cancer that ends human life. Like many other cancers, lung cancer is difficult to diagnose in the early stages, and by the time it is discovered, it is already in the late stages. It is very difficult to treat this final stage of cancer. In fact, lung cancer shows some symptoms in the early stages, and patients at high risk of lung cancer should be alert.

We know that when cancer reaches the final stage, it is almost incurable, and most treatments are just to prolong life. Lung cancer is also such a cancer, but if it can be detected early, it will have a positive effect on controlling the progression of the disease and treating the disease. Lung cancer will have some symptoms in the early stage. Let's take a look at several symptoms of early lung cancer.

1. Cough

Cough, the early cough symptoms of lung cancer are mostly irritating coughs. The characteristics of early coughs of lung cancer are that paroxysmal irritating coughs dominate, and there is a feeling of coughing. Generally, there is no sputum or a small amount of white foamy sputum. Secondary infection may cause purulent sputum. If such a cough occurs and the patient does not improve after 2 weeks of anti-inflammatory treatment, then you should be alert to the possibility of lung cancer. If there are changes on the basis of primary or chronic cough, even if there is "clear trachea" and "shortness of breath", you need to pay attention. Patients with hemoptysis, chest pain, chest tightness, fever and other symptoms should also be vigilant.

2. Chest abnormalities

Early lung cancer may also cause chest tightness and chest pain, but the symptoms are generally mild and the location is unclear. When the tumor invades the pleura and chest wall, and a clear location is detected, the pain may intensify. In addition, by observing the patient's face, the patient may appear pale and dull, with a darker or abnormally sallow complexion, especially on the cheeks. The crab claw pattern in the zygomatic region will increase as the clinical stage worsens. Male breasts may become enlarged, and mentally, there may be multiple neuritis.

3. Abnormal breathing

Patients with early lung cancer may experience shortness of breath, tumor obstructive pneumonia, atelectasis, pleural effusion, diffuse alveolar damage that may cause fever, obstructive pneumonia, or cancer toxins. Patients may also have significant cachexia.

Cough, especially irritating cough, with chest tightness, chest pain, shortness of breath and other abnormalities, after excluding abnormalities caused by other diseases, and after a period of anti-inflammatory treatment, if there is no way to relieve, then you should be alert to whether it is an early symptom of lung cancer. If you can start to control the disease in the early stage of lung cancer, it will be beneficial to restore lung health.
