Nowadays, there are more and more patients with lung nodules, and many hospitals have even opened new pulmonary nodules clinics to meet the diagnosis and treatment needs of patients and friends.
So the question is, what is the reason for the increasing number of lung nodules? There are rumors that lung nodules appear after receiving the new crown vaccine , causing people to worry about the side effects of the new crown vaccine. Is this really the case? Please see this article to analyze whether
lung nodules are related to the new crown vaccine?
Regarding the rumors that the new crown vaccine is induced by lung nodules, on September 24, Academician of the Chinese Academy of Sciences Gao Fu had explained this at the Mozi salon hosted by Shanghai Institute of University of Science and Technology of China. There is currently no evidence to show that vaccination is related to the occurrence of diseases such as pulmonary nodules. In fact, if you have some understanding of the principles of the new crown vaccine and lung nodules, you will know that the two are not very related.
Lung nodules are actually the image shadow of the lungs. The imaging definition of lung nodules is a small lesion completely surrounded by the lung parenchyma and has a clear boundary, with a diameter of no more than 30mm. If the diameter is greater than 30mm, the lesion is a lump rather than an nodule and , and the probability of malignancy is significantly higher, that is, the possibility of lung cancer is high.
Although there are many reasons for lung nodules, they are mainly divided into two types. One is lung nodules caused by viruses, bacteria, Mycoplasma , fungi and other infectious pathogens, and the other is due to non-infection reasons such as pneumoconiosis, tumors, etc. The vaccine, especially the rumored Sinovac vaccine, belongs to the inactivated vaccine , which means that the virus has been "killed" during the preparation process and has lost the ability to infect and replicate, so it will not infect our lung tissues and cause lung nodules. From research and development to market, the
vaccine has undergone preclinical trials and layers of clinical trials, rigorous research and development and trials. A lot of trial data has been accumulated before it is launched, and it does not indicate the risk of lung nodules. That's why experts can say that there is currently no evidence that vaccines can lead to lung nodules. Then why do people feel that there are more and more patients with lung nodules?
lung nodules are increasing, which is related to three factors
1. People do physical examinations more frequently
On the one hand, people attach importance to physical examinations, and many units pay attention to physical examinations once a year. Secondly, with the outbreak of the new crown pneumonia epidemic, people have undergone lung CT examinations more frequently, especially when nucleic acid tests were not popular at the beginning, most of them rely on the clinical judgment of doctors and the examination of CT, which will lead to many patients with fever and respiratory symptoms undergoing CT examinations in the lungs. This will also greatly increase the detection rate of lung nodules.
2.CT equipment is more advanced
. With the development of science and technology, CT is no longer an examination equipment that only large hospitals have. Even instruments with increasingly higher resolution have been developed. We can see more clearly, and there will be many tiny lung nodules that cannot be found before. At the same time, the advent of artificial intelligence software can help imaging doctors interpret CT reports, resulting in most reports having words such as small lung nodules.
3. Environmental pollution factors
We know that environmental pollution such as smoking, air pollution, and automobile exhaust, the most direct entry of environmental pollution into the human body is the lungs. With the continuous upgrading of human industrialization, we say that the health of our human lungs is also under greater threat, which is also a factor that increases the incidence of lung nodules.
At the same time, environmental pollution will lead to lung infection in the human body , low immunity and other diseases caused by it, and these lung infections and other diseases will also induce the occurrence of lung nodules.
Summary
In short, the increase in detection of lung nodules has little to do with the new crown vaccine. We cannot ignore the important role of the new crown vaccine in fighting the epidemic because of some rumors. Moreover, most lung nodules (longest diameter <5mm)>
