Lung nodules with smooth edges, blurred edges or calcification within the lesion, or without burrs, lobulation, pleural depression signs, vacuolar signs, vascular signs, etc. are usually considered benign, but it can not be said to be fine, and regular follow-up is still needed.
In addition, isolated solid lung nodules with a diameter of less than or equal to 8 millimeters or partially solid lung nodules, and isolated ground-glass lung nodules with a diameter of less than or equal to 5 millimeters are generally unlikely to be malignant, and regular follow-up is sufficient.
If the edges of the lung nodules are not regular, there are burrs or lobes, or pleural depression sign or vacuole sign or vascular sign, the possibility of malignancy is greatly increased, and it is necessary to go to the hospital for a definite diagnosis.
When you find lung nodules, you must go to the hospital in time for consultation, under the guidance of the doctor to carry out the appropriate treatment, do not because of the temporary lack of obvious clinical symptoms and paralysis, so as to avoid delays in the condition.
