Lung nodules are categorized into benign and malignant nodules. In the case of malignant nodules, the infiltration area is large and the degree of malignancy is high, so it is usually necessary to remove one lobe of the lung to completely remove the lesion. If the nodule is benign, but the nodule growth rate is fast, a short period of time to become larger and involve a lobe of the lung also need to remove a lobe. 1. Malignant nodule: if there is a nodule in the lung with burrs and irregular shape around it, and the disease is malignant nodule, and the infiltration area of malignant cells is large and the degree of malignancy is high, it is necessary to resect one lobe of the lung, and even clear the lymph of the lung to completely remove the lesion, so as to prevent the tumor from spreading. 2. Benign nodules: Generally, benign nodules do not need to be treated and follow-up observation is sufficient. When the benign nodule grows fast and becomes bigger in a short time and involves one lobe of the lung, it may be benign malignant and affects the respiratory function of the lungs, and at this time, it is also necessary to remove one lobe of the lung to eradicate the lesion. Depending on the nature of the lung nodules, the choice of treatment is also different, we recommend that patients go to a regular hospital in time to avoid delaying the condition.
