How to detect the symptoms of lung cancer as early as possible? Revealing the 4 typical symptoms of lung cancer

Hemoptysis is an early signal of the onset of lung cancer in central lung cancer because the tracheal mucosa is rich in blood vessels, but the blood is very small. Peripheral lung cancer is far away from the trachea, so hemoptysis usually occurs later.

When lung cancer spreads to the vagus nerve of the human body, the patient may experience symptoms of arrhythmia. At this time, the problem of lung cancer is already quite serious, and the patient may also be in danger of life. Experts point out that because the symptoms of lung cancer are so serious in the later stages, patients should pay more attention to detecting the disease in the early stages.

How can we detect the symptoms of lung cancer as early as possible?

① Hemoptysis: The onset of lung cancer is an early signal of central lung cancer because the tracheal mucosa is rich in blood vessels, but the blood is very small. Peripheral lung cancer is far away from the trachea, so hemoptysis usually occurs later.

② Low-grade fever: low-grade fever with unknown causes, manifestations of lung cancer, especially intermittent fever (reportedly accounting for 70%), combined with the above symptoms, should be taken seriously. Report symptoms such as irritating cough, changes in cough patterns of primary tracheitis, or persistent and intractable cough (ineffective after more than three weeks of treatment) may all be manifestations of lung cancer and should be further examined.

③ Choking cough as a symptom of lung cancer: If a person is over 40 years old and has an unexplained, stubborn, irritating cough, it is often a symptom of lung cancer, especially the central type, because the trachea is stimulated by the tumor and causes spasmodic contraction. Therefore, the precursor signals of central lung cancer are revealed much earlier than those of peripheral lung cancer.

④ Chest pain: chest pain is also an early symptom of lung cancer. It is sharp and stabbing in nature. This symptom of lung cancer often appears early in undifferentiated lung cancer.

Finally, experts pointed out that lung cancer patients must not think that the symptoms of lung cancer only appear in the lungs. In fact, symptoms of lung cancer may appear throughout the body, such as heart disease, limb paralysis, etc., which may be complications induced by lung cancer. In order to avoid these serious complications, patients should find out the characteristics of their illness as soon as possible based on the above introduction.
