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

Experts say that the symptoms of early lung cancer are not obvious. The main symptom of patients is coughing. As the disease progresses, symptoms such as coughing up blood or chest pain will also appear. At this time, the patient should pay attention and go to the hospital for chest imaging examination in time. Lung CT is recommended, which can diagnose the disease well. In order to give everyone a detailed understanding of the early symptoms of lung cancer, the following is a detailed introduction for you.

The most common symptom of lung cancer is cough, which is often an irritating dry cough with a high pitch, like the sound of knocking on metal. Bloody sputum or blood in sputum is the most typical symptom of lung cancer. These sputums are often mixed with detached cancer cells, and the positive rate of sputum cytology examination is high. When a tumor blocks the trachea, patients often feel chest tightness, shortness of breath, and fever. The fever is sometimes better and sometimes worse, and it is difficult to cure. At the same time, systemic symptoms such as loss of appetite and weight loss may also occur.

Generally speaking, a large proportion of people with lung cancer have early signs, such as coughing and blood in sputum. However, since they are often ignored, many people are already in the late stage when they come for check-ups. Therefore, special attention should be paid to regular physical examinations.

So how do we detect lung cancer early? If we find that the irritating cough lasts for 2-3 weeks and anti-inflammatory treatment is ineffective, and the cough changes in nature and turns into an irritating dry cough with blood in the sputum, we should be alert to the occurrence of lung cancer. Patients who are highly suspected of lung cancer must undergo bronchoscopy or percutaneous lung puncture to obtain tissue pathological evidence.

The above introduces the early symptoms of lung cancer. Experts say that as the incidence of lung cancer continues to rise, people have a better understanding of the common knowledge about lung cancer. Therefore, people who have the habit of smoking in life must quit smoking, so as to prevent the occurrence of lung cancer.
