First of all, let me tell you a little bit: pulmonary nodules are more benign than malignant! Don't panic if you find a lung nodule!
I am Dr. Li Yaoyuan, Department of Oncology, Guang'anmen Hospital, China Academy of Chinese Medical Sciences. Although pulmonary nodules are mostly benign, lung cancer still ranks first in the incidence of malignant tumors in mainland China. Therefore, early diagnosis and early treatment of lung cancer are very important, and many lung cancers manifest as lung nodules in the early stage.
The judgment of benign and malignant pulmonary nodules is very important! You can't easily let go of the malignant, and try not to mistakenly cut the benign.
Malignant pulmonary nodules have 5 characteristics:
First, malignant solid nodules with irregular morphology, unclear borders, lobulation, and visible short hair defects. It is mostly about two millimeters.
Second, pleural depression or vascular hormonosis appears
Because early lung adenocarcinoma and lung squamous cell carcinoma have a certain contractile force, they can stretch the adjacent pleura to form pleural depression, and can also stretch the surrounding interstitial to encompass the blood vessels, forming vascular end-of-the-road.
Third, bronchial amputation or bronchial inflation occurs
Because squamous cell carcinoma of the lung or poorly differentiated adenocarcinoma often causes bronchial rupture to be amputated, the well-differentiated bronchi is generally not a problem, but the inside of the relatively small tumor can often be connected to the bronchial passage.
Fourth, vacuole syndrome
In the early stages of lung cancer, there may be a section of the normal lung or a small bronchial tube that is less than five millimeters in size.
Fifth, mixed membranous nodules have clear membranous opacities at the edges, accompanied by pleural traction.
Because lung cancer is a highly malignant tumor and is very harmful to our lives and health, everyone must follow the doctor's instructions when detecting lung nodules, observe them regularly, and take timely measures when they find out the bad truth.
What are the characteristics of benign pulmonary nodules?
Many fans also left messages, panicking when they found lung nodules, and wanted to know which ones were identified as benign nodules.
1. Non-smoking, no high-risk factors (female), solid nodules less than 5 mm in the lungs, basically benign (smokers should be cautious).
2. Solid nodules within 30 years of age, less than 3 cm, within 3 cm of the peripheral subpleura, are basically benign, mostly tuberculous bulbs.
3. Newly ground-glass nodules that appear within 1 year are basically benign.
