What are pulmonary micronodules?

The lungs control our breathing. Once there is a problem with our lungs, it will not only affect our breathing but also cause harm to our bodies. Therefore, we must protect our lungs in our daily lives. It is best not to develop bad habits such as smoking. In addition, we can also eat more foods that nourish and moisturize the lungs. Below we will introduce what are micro-nodules in the lungs.

Small lung nodules are a common and difficult to diagnose disease in thoracic surgery. Its diagnosis and treatment have always been a difficult point in clinical practice and a hot topic of discussion. Its etiology is complex, its clinical manifestations lack specificity, and its diagnosis is difficult and prone to misdiagnosis and missed diagnosis.

Pathological analysis

Also known as 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. Literature reports that about 20% of patients with small lung cancer have micro-metastasis to the lymph nodes. Therefore, some patients miss the best time for surgery.

Pathological characteristics

The physiological and anatomical findings of small pulmonary nodules are that they are multiple and can fuse together to form masses, or they can be solitary. They are round pulmonary nodules with a diameter of 1-2 cm. Cavities may occur in the later stages, or they may be complicated by infection.

In the above article, we introduced the importance of lungs to our human body. Once there is a problem with our lungs, it will cause harm to our body, so we must protect our lungs well. The above article introduces in detail what are micro-pulmonary nodules.
