Whether benign lung nodules can be eliminated depends on the specific cause of the lung nodules, that is, some benign lung nodules can be eliminated and some benign lung nodules cannot be eliminated but persist. Lung nodules belong to the concept of imaging, not a specific disease, generally refers to the presence of rounded high-density lesions with a diameter of less than 3cm in the lungs, which can be categorized into benign and malignant lung nodules according to their nature. Malignant lung nodules are characterized by the presence of persistent enlargement and can invade surrounding tissues. Benign lung nodules do not usually show persistent enlargement, but whether or not they can be eliminated depends on the cause. Inflammatory lung nodules caused by generalized infectious inflammation of the lungs can be eliminated with anti-infective treatment. Dense lung nodules produced by inflammatory stimulation of the lungs are mostly old lesions and will not be eliminated unless surgically removed. There are also some benign pulmonary nodules that are structures in the lungs themselves, such as lymph nodes in the lungs that are visualized and will not go away.
