Normal people have nodules in their lungs. Is there a nodule in the lung serious?

After the reform and opening up, everyone's pockets are bulging and they no longer worry about food and clothing, so many people pay more and more attention to their health, so the annual physical examination has become a necessary item for many people. In these routine physical examination items, including chest CT, it is not too tight not to check. As soon as the pulmonary nodules are detected, I feel uneasy when I see the need for regular follow-up visits.

At present, there is no exact data on the number of people diagnosed with pulmonary nodules in China, but according to the inspection results of various hospitals, the detection rate of pulmonary nodules in people over 40 years old in China is as high as 20%, while the population over 40 years old in China is about 550 million. It is roughly estimated that there are more than 654.38 billion patients with pulmonary nodules in China.

Does pulmonary nodule have any serious harm to human body?

The biggest harm of pulmonary nodules to people is canceration, followed by increasing psychological burden. At present, many people have been diagnosed with pulmonary nodules. Although the proportion of malignant tumors is not high, after all, the base is large, so the number of malignant pulmonary nodules is not small.

Perhaps everyone is most concerned about the benign and malignant lung nodules. Although it can't be 100% from the appearance to determine whether the lung nodule is benign or malignant, it is basically judged. Generally speaking, the smaller the diameter of pulmonary nodules, the less likely they are to be malignant and cancerous. Generally speaking, lung nodules smaller than 3mm can almost be considered benign, and the possibility of canceration is 0.2%.

If the edge of a lung nodule is irregular, with lobulation, vacuoles and burrs, it can basically be considered malignant. In addition, if the blood supply of pulmonary nodules is more, the possibility of malignancy is also greater.

If it is highly considered that lung nodules are malignant, try to remove them surgically. If the nature of pulmonary nodules is difficult to judge, we can make a definite diagnosis by regular examination or direct pathological examination. However, it should be noted that pathological examination is only a part and cannot fully represent the whole lung nodule, so there will naturally be misdiagnosis.
