What are the most typical symptoms of lung cancer? 4 most typical symptoms of lung cancer

Pericardial effusion. Cancer invasion of the vagus nerve can accelerate the heart rate, invasion of the myocardial conduction system can cause arrhythmia, and invasion of the pericardium can produce pericardial effusion and symptoms of constrictive pericarditis.

Since lung cancer patients will develop pleural effusion during the course of the disease, the lungs can easily develop some typical symptoms of the disease due to infection. Experts point out that as long as patients can determine that they have lung cancer based on these lung cancer symptoms, they can receive timely and effective treatment. We must pay more attention to our bodies.

What are the most typical symptoms of lung cancer?

1. Pericardial effusion

Cancer invading the vagus nerve can accelerate the heart rate, invading the myocardial conduction system can cause arrhythmia, and invading the pericardium can produce pericardial effusion and symptoms of constrictive pericarditis.

2. Hoarseness

Hoarseness occurs when lymph node metastasis compresses or invades the recurrent laryngeal nerve (most common on the left side). Laryngoscopic mediastinal examination shows vocal cord paralysis on the affected side.

3. Diaphragm paralysis

Compression of the phrenic nerve causes paralysis and ascent of the ipsilateral diaphragm. X-ray fluoroscopy shows slow movement of the diaphragm on the affected side and contradictory movement when breathing in through the nose.

4. Localized stridor

It is a unilateral localized wheezing sound, especially the wheezing sound during the inspiratory phase, which does not disappear after coughing. It is one of the early signs of lung cancer, but it is short-lived and easily ignored.

In the late stage of lung cancer, patients are more likely to experience shortness of breath, and some also have pleural effusion. Almost all patients with advanced lung cancer that has spread regionally have shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and myocardium flows back through the lymph nodes in the middle of the chest. If these lymph nodes are blocked by tumors, this tissue fluid will accumulate in the pericardium to form pericardial effusion or accumulate in the chest cavity to form pleural effusion.

Finally, experts pointed out that in order to alleviate the pain of lung cancer patients in the late stage, the family members of lung cancer patients should take good care of the patients' diet and daily life, so that they have a comfortable environment and can recuperate with peace of mind. If the condition is more serious, lung cancer patients should be hospitalized for treatment, which will greatly increase the chance of curing lung cancer, especially in the late stage, when the condition of lung cancer is difficult to control.
