Obvious symptoms of lung cancer?

summary

Lung cancer has become the first "cancer killer" in the world. The high mortality of lung cancer is mainly due to the lack of effective means of early detection. About 80% of the patients are in the middle and advanced stage at the time of initial diagnosis. For lung cancer, it must be treated in the early stage of lung cancer, which is very helpful for the recovery of the disease. Once it is in the late stage, the consequences are unimaginable, then the obvious symptoms of lung cancer? I'd like to share my views with you.

Obvious symptoms of lung cancer?

1. Chest pain. There is a certain difference in the degree of chest pain, and this difference depends not only on the severity of the disease, but also on the specific individual quality of the patient.

2. Coughing up blood. This symptom is mainly caused by the invasion of tumor cells into the bronchial mucosa, but may be due to the different quality of the patient's body and lead to different degrees of illness, and the performance of blood in sputum is not the same. With the aggravation of the disease, once the tumor cells infiltrate into the blood vessels, it will cause massive hemoptysis, and even endanger the life of the patient.

3. Clubbing fingers. The early common symptoms of lung cancer may also appear clubbing finger, which means that the first segment of the toe becomes hypertrophy, the nail will also be protuberant and curved, and often accompanied by pain, which is also an early symptom of lung cancer that can not be ignored. 4. Cough. Cough is the most common symptom, with cough as the first symptom accounting for 35% - 75%. Cough caused by lung cancer may be related to changes in bronchial mucus secretion, obstructive pneumonia, pleural invasion, atelectasis and other chest complications. When the tumor grows in the bronchial mucosa above the large diameter and sensitive to external stimulation, it can produce cough similar to that caused by foreign body like stimulation. The typical manifestation is paroxysmal irritative dry cough, which is often difficult to control by general antitussive drugs. When the tumor grew in the small bronchial mucosa below the segment, the cough was not obvious, or even no cough. For patients with smoking or chronic bronchitis, such as the degree of cough aggravating, frequency conversion, cough nature changing, such as high pitched metal tone, especially in the elderly, we should pay close attention to the possibility of lung cancer.
