Pulmonary nodules are tissues wrapped by normal lung tissue. When passing the inspection of relevant instruments, it can be observed that the boundaries are clear. Common pulmonary nodules can be divided into two categories: breast milk nodules and ventricular nodules. The density of ground glass nodules is similar to that of normal lung tissue, but the density of ventricular nodules is higher. Early pulmonary nodules are difficult to identify by our own senses. Because early pulmonary nodules have no obvious symptoms, they will not cause human discomfort. Only a few patients have mild dry cough, phlegm and no blood. Most of them passed, and pulmonary nodules were confirmed during physical examination. The statistical results show that about 30% people suffer from pulmonary nodules during physical examination every year, and about 2% patients suffer from malignant pulmonary nodules during physical examination in high-risk groups.

A large number of harmful substances in tobacco will seriously reduce lung function. Even after smoking, the residue in the space will cause serious harm to the human body. The point to be emphasized here is that the harm of tobacco should not only attract the attention of smokers, but also secondhand smoke. In the process of cooking or cooking, the content of PM2.5 in the air rises several times faster. The harm to human lungs is equivalent to inhaling two boxes of cigarettes. Automobile exhaust, gas in newly renovated houses, detergent with pungent smell and other things that are often contacted. Increase the burden on human lungs and promote the growth of lung nodules.

With the continuous development of science and technology and the wide application of CT technology, it is easier to find nodules than the previous chest technology. Therefore, the number of patients with pulmonary nodules has also increased. It takes a detailed examination to know the cause, but according to his physical condition, I can conclude that he may have pulmonary nodules. After receiving the inspection report, Mr. Song's illness proved to be pulmonary nodules. He was very worried after hearing the diagnosis. I told Miss Song not to worry. We will make a judgment based on his physical condition. In addition to cooperating with the doctor's treatment, we should also pay attention not to smoke and drink in our daily life.

We can look at Mr. Li's inspection report first. In fact, in the video, we come to the conclusion that the chest is symmetrical on both sides, the front and rear mirrors are willful, and the texture of both lungs is clear. This shows that the image inspection is still very clear. This shows that image detection is advantageous. In other words, you can see inside the human body, such as the lungs. We saw an absolute image with a diameter of about 3 mm in Mr. Song's right middle lung. The existence of this image can prove that Mr. Song has lung nodules, but the lung nodules are benign and malignant. At present, the trachea is unobstructed in other aspects, and there should be no unusually large lymph nodes in the mediastinum, so it can be concluded that this knot is a benign category, but the suggestion to Teacher Song is to let him check it regularly. Because it is benign.
