Modern society is getting better and better, people also pay attention to the occurrence of diseases, some units will organize a yearly physical examination. Lung nodules are very common in medical checkups, and even if the patient is not a smoker, there is still a possibility of developing the disease. Lung nodules may not only take root in the lungs, but also in other parts of the organs such as the eyes and the chest. The chest is the most popular place for nodules and has a higher probability of being invaded. There are two main categories of lung nodules as shown by imaging. In addition to purely glassy nodules and mixed nodules, solid nodules are now appearing more and more frequently. Lung nodules do not necessarily become cancerous, but there are three conditions that need to be dealt with as soon as possible According to valid research data, lung nodules are malignant in about one-fifth of patients. Experts warn that you should not be overly complacent when you find a benign lung nodule, but you should observe the internal changes of the nodule many times, and if you don’t pay attention to it and allow it to develop, your lungs will only be hurt more. One condition is the appearance of a moon ring halo around the nodule. Simply put there is a small growth on the border of the lungs, like a sore that usually swells up in the mouth. If there is inflammation, the patient will have an increased cough and sputum, and it is likely that the cancer has taken over the nodule. The second condition is a burr around the nodule. Benign nodules are smooth, but if there are obvious corners and burrs in the image, it is the early stage of the development of the nodule into a tumor, and the patient’s chest pain will be aggravated. If there is constant pain in the chest when the nodule is detected, the patient should be careful of cancerous lesions. The last situation is that there are blood vessels in the nodule. If the patient has a high fever that does not go away, there may be a tumor in the lungs, and the blood vessels in the nodule will become inflamed and swollen if they are blocked, and when a certain period of time passes, the nodule will grow into a tumor, and localized cancer will inevitably occur. What should I do if I find a lung nodule? Should they be observed conservatively or should they be operated at the earliest possible time? When a nodule is found for the first time, if it is benign, observation will be recommended. This is because the images may not be clear at one time, or the patient is obese and the lungs produce overlapping shadows. There is no problem with normal life and diet. If the nodule has become cancerous, the choice of surgery or pathologic testing can be made initially, depending on the patient’s wishes. If the diagnosis and treatment are made in good time, the survival of the patient after the operation increases dramatically and recurrence is very unlikely. Early diagnosis and treatment can slow down the development of lung cancer, and the possibility of diagnosis and treatment is very high. Older people and long-term smokers should keep a close eye on their lungs after the development of nodules. If a lung nodule has been found once and now recurs for the second time, it is important to have a comprehensive examination in time to prevent the spread of cancer cells. Physical examination found lung nodules should not be like Mr. Wang, avoid medical treatment, after review may be ordinary benign nodules, if they have been hiding plus the psychological burden, and then come back to the doctor will only miss the best time, a small problem into a big disease.
