Multiple nodules in the lungs are more benign than malignant. Most of the multiple nodules in the lungs are due to benign lesions caused by tuberculosis of the lungs, but the presence of malignant lesions in the multiple nodules in the lungs is also a certain possibility, and they cannot be completely excluded. The difference between benign and malignant multiple nodules in the lungs: 1. When multiple nodules in the lungs are benign lesions, they are usually caused by inflammation, tuberculosis, hemorrhage and other factors, and common diseases include inflammatory pseudotumor, misshapen tumor, tuberculosis ball, pulmonary nodular disease and other diseases. 2. When multiple nodules appear in the lungs as malignant lesions, they are usually considered to be related to metastatic tumor, bronchoalveolar lung cancer and other diseases. CT-guided examination should be carried out in the hospital in a timely manner to clarify the benign or malignant nature of the multiple nodules, so that treatment can be carried out quickly. If multiple nodules appear in the lungs, you should go to the hospital in time to improve the relevant examination, so as not to delay the condition.
