To determine whether a lung nodule is benign or malignant, it is usually necessary to analyze and distinguish the nodule with a sound breast enhancement CT. Usually observe the size of the lung nodule, for the lung nodule higher than 5mm, the probability of benign is high, while for the lung nodule of 1~3cm, the probability of its malignant malignant tumor is higher, and the larger the lung nodule, the higher the probability of hepatocellular carcinoma. Secondly, the shape of lung nodules occurs the signs of malignant malignant tumor, such as shallow lobulation, short burr side sign, pleural notch sign, vacuolization sign, capillary collection sign and other conditions. Lung raise CT discovery of lung nodules showing no enhancement or mild to moderate enhancement may be malignant malignant tumor. The lung nodules that do not strengthen or are relatively highly strengthened may be benign nodules.
There are many factors that cause lung nodules, most of which are caused by inflammation of the lungs or tuberculosis after treatment of growth, liver fibrosis or thickening, lung nodules are usually attributed to benign changes in the disease, do not have to do a unique solution. However, some of the benign nodules may change into malignant lesions. Therefore, once lung nodules are detected, it is important to have a regular medical checkup within 2 years. Once the lymph nodes are found to have a tendency to become malignant, the disease can be detected and treated early to minimize the harm caused to the body. In addition, long-term smoking or staying in a polluted environment for a long time can also cause lung nodules, and congenital hereditary elements are also one of the primary factors causing lung nodules. The fact that you have to have a regular medical checkup can help you to detect the disease at an early stage.
The prevention of lung nodules needs to start from both oneself and the surrounding environment. Patients need to quit smoking and strengthen the resistance, do more aerobic exercise to exercise lung function, such as climbing mountains, heights, outdoor activities, and absorb more fresh air. As for the external environment, if there is haze, dust, chemical fumes stimulating environment, you should consciously wear a mask, and often, regularly open the windows to ventilate the indoor air circulation is helpful. Lung nodules are mostly scars left after pneumonia, tuberculosis through their own immunity or treatment, so when symptoms of pneumonia or lung nodules, tuberculosis, in accordance with the regimen standardized treatment.
The treatment of lung nodules needs to be based on the actual situation, for most of the substantial nodules are benign, as long as the body has no discomfort symptoms, regular review can be, is not necessary to do other treatment. But if you suspect that the nodules have a malignant tendency, then we need to timely surgical treatment, and do the pathology test.
