Ground glass nodule 1.7cm*1.4cm in the upper lobe of the right lung, it is necessary to determine the nature of the nodule in order to determine whether it is serious or not, only the malignant nodule is more serious, and it needs to be surgically resected. There are mainly benign and malignant lung nodules. Generally, benign nodules do not need treatment for the time being, and regular follow-up observation is sufficient. If a malignant nodule is detected at an early stage and the nodule is still in the carcinoma in situ or early lung cancer stage, thoracoscopic surgery can be performed to remove the nodule. A 1.7cm*1.4cm ground-glass nodule in the upper lobe of the right lung is a large nodule, which needs to be combined with other features of the nodule to determine whether it is early lung cancer, such as whether there are vacuolar signs, vascular signs, pleural pulling signs, etc. The nodule should be taken seriously. Larger nodules need to be taken seriously, but there is no need to be overly panicked, most of them have a better prognosis after active treatment, and can lead a normal life after surgery.
