Small pulmonary nodules appear in the body, what should I do?

Pulmonary nodule is actually an imaging concept, not an independent disease. Many diseases can lead to pulmonary nodules. Generally speaking, nodules are seen on CT or chest radiographs of the lungs, which are obviously different from the surrounding lung tissues. Pulmonary nodules refer to shadows with diameters less than 1 cm. Pulmonary nodules are widely known because a small part of them may be lung cancer, but in fact, most of the pulmonary nodules found by physical examination are benign lesions, and the most common reasons are scars left by infection, inhalation and deposition of pollutants, especially pulmonary nodules. In recent years, low-dose CT has been widely used in lung health screening in China. Nodules larger than 2mm can be found, and the detection rate of pulmonary nodules is gradually increasing. At the same time, due to the influence of air pollution such as smog, the incidence of pulmonary nodules has also increased.

Pulmonary nodules can be divided into pure ground glass nodules, partial solid ground glass nodules and pure solid nodules according to nodule density. Among these three types of nodules, malignant lesions accounted for 65438 08%, 63% and 7% respectively. 80%-90% of the pulmonary nodules found in the initial CT examination are benign lesions, but we should attach great importance to them, because there is still a certain proportion of early lung cancer, and regular examination is essential. It is generally recommended to review once every 2-3 months. The reason why we can choose this way to arrange observation is mainly from the biological behavior of tumors. There is a doubling time for tumor growth, which is generally considered to be 2 months to 12 months, that is, the tumor can grow twice as fast in 2 months, so it is still early for lung nodules to grow twice, and it is difficult to spread and metastasize quickly. Even lung cancer can be found at an early stage as long as it is checked regularly. Through minimally invasive thoracoscopic surgery, the cure rate is still relatively high, the trauma is small, the pain is light, the postoperative recovery is fast, and chemotherapy and radiotherapy are not needed.

Patients with pulmonary nodules need to put their minds right. Some people often frighten themselves to death before the disease develops, and they are anxious and depressed all day. Moreover, such mental state often leads to worse and is not good for the body. The benign rate of pulmonary nodules is very high. If you are not at ease, you can check it regularly. If the existence of pulmonary nodules has become a heart disease and seriously affects personal life, minimally invasive surgery can be performed. If you don't want surgery, you can consider doing PET-CT to determine the benign and malignant lesions more accurately, but the cost of this examination is relatively high.

As we all know, smoking is harmful to health. But the biggest impact of smoking on the lungs is that it will lead to canceration of lung nodules, so for personal health, we must insist on quitting smoking. In addition, personnel engaged in ore mining and aluminum manufacturing industries should pay attention to personal protection and conduct regular lung examinations. Because these people are engaged in special jobs, they inhale a lot of minerals every day, and lung nodules will appear over time, leading to silicosis. Therefore, special attention should be paid to protection and inspection. The emergence of cancer is often to choose people with low immunity. Regular physical exercise can not only reduce weight, improve vital capacity, but also improve immunity and reduce the possibility of malignant pulmonary nodules to a greater extent. Therefore, we should strengthen physical exercise and enhance immunity.
