What's wrong with small lung nodules

Small lung nodules are relatively unfamiliar to many people. This disease is also clinically called small lung cancer. Small lung nodules are a common disease. Many people do not know what small lung nodules are. This condition has a lot to do with people’s habits, such as smoking.

1. In theory and medicine, this disease is called small lung cancer. Peripheral lung cancer tumors with a diameter of ≤2cm are called small lung cancer, and those with a diameter of ≤1cm are called micro lung cancer. Small lung cancer is not necessarily early lung cancer, especially adenocarcinoma and small cell undifferentiated carcinoma, so everyone must pay attention to it so as not to miss the best time for surgical treatment.

2. In real life, many people do not know what small lung nodules are. The physiological and anatomical findings of small lung nodules show that they are multiple and can fuse into masses. They can also be single, round nodules with a diameter of 1-2 cm. Cavities may occur in the later stages, or they may be complicated by infection.

3. Generally, long-term smokers with a smoking age of more than 20 years, who smoke more than 20 cigarettes a day, or people who are exposed to passive smoking; those who are over 40 years old; those who have symptoms such as chest pain, cough, unexplained blood in sputum, emaciation, weight loss, etc., must pay great attention to this phenomenon, as there is a high possibility of small lung nodules.

4. Many people do not know what lung nodules are. Lung nodules are a common and difficult to diagnose disease in thoracic surgery. Their diagnosis and treatment have always been a difficult point in clinical practice and a hot topic of discussion. The etiology is complex, the clinical manifestations lack specificity, and diagnosis is difficult and prone to misdiagnosis and missed diagnosis.
