In recent years, with the gradual improvement of people's awareness of health needs and the popularization of low-dose high-resolution thin-slice chest CT, more and more people are finding pulmonary nodules during physical examination or when visiting other diseases. It is not uncommon to encounter many patients in the outpatient clinic, holding an imaging report with "pulmonary nodules" written on it, and the first thing they say when they enter the door will ask, "Doctor, do I have cancer?"
Are lung nodules really all "bad people"?
Are nodules the same as cancer?
Or is it likely to become cancerous?
Are lung nodules = lung cancer?
Lung nodules ≠ lung cancer! A number of studies at home and abroad have shown that most of the pulmonary nodules are benign lesions, including old lung changes, inflammation, fibronodule foci, granulomas, pulmonary artery malformations, hemangiomas, etc. A small number of lung cancers are cancer, and even if it is cancer, it may be an early-stage cancer, and it can be treated in a timely manner with appropriate treatment.
Difference between CT and X-ray
The main thing to look at is to look at the whole, and the CT is to look at the slices
Which nodules may be high-risk nodes?
Looks like
The longer the nodule is, the more malignant it may be, such as lobulation, burrs, pleural traction, bronchiols and vesicles, eccentric thick-walled cavities, etc.
Look at the location
Malignancy is more common in the upper right lung.
Look at the changes
During regular reexamination, the nodule continues to enlarge, and it is necessary to be alert for malignancy.
Look at the size
Solid nodules larger than 15 mm or mixed ground-glass nodules larger than 8 mm are considered high-risk nodules.
How to prevent pulmonary nodules on a daily basis?
Prevention is better than cure, and in life and work, we should try to avoid the factors that cause pulmonary nodules, such as:
Quit smoking and stay away from secondhand smoke;
Avoid inhaling oil fumes;
Keep away from harmful substances such as decoration and occupational exposure;
Avoid staying up late;
Eat a balanced diet and exercise moderately.
