Where are the early symptoms of lung cancer manifested? The early symptoms of lung cancer are manifested in 4 aspects

In the health science knowledge of our people over the years, we can roughly find that lung cancer is divided into three stages, namely early lung cancer, mid-stage lung cancer and late-stage lung cancer. If early and mid-stage lung cancer can be treated in time, it is very likely to be cured. So we must know what the early symptoms of lung cancer are?

1. Hemoptysis:

About 50% of lung cancer patients have symptoms of hemoptysis. Among them, if a male smoker over 40 years old has blood in his sputum, blood streaks or small blood clots, the possibility of lung cancer is very high, which is also one of the early symptoms of lung cancer.

2. Cough:

Secondly, cough is a common symptom of lung cancer in the early stage, but this symptom is not too obvious. Cough can be mild and dry cough or severe cough, with varying amounts of sputum. However, in patients with chronic long-term cough, once the cough changes in nature, or becomes more frequent or occurs at night, be alert to lung cancer. Continuous and uncontrollable cough is one of the most painful symptoms of lung cancer.

3. Chest pain:

Symptoms of lung cancer generally include chest pain, but this symptom is usually intermittent and mild chest pain. It manifests as dull pain or piercing pain, which can last from minutes to hours. If the tumor invades the pleura, the pain will be more severe, continuous and fixed. If chest pain recurs in early lung cancer, the prognosis is poor if the pain recurs later.

4. Chest tightness and shortness of breath:

In addition to tumors blocking the bronchus and causing atelectasis and lung inflammation which can cause chest tightness and shortness of breath, these symptoms are generally more obvious in the late stages of lung cancer, especially when a large amount of pleural effusion is present.
