Compared to their cancerous counterparts, benign pulmonary nodules do not metastasise to other body parts and are usually non-life threatening. Benign lung tumours are benign as there is very little growth or change in size. In rare cases, it is possible for the nodules to disappear completely without any treatment, as the body’s natural healing process has addressed the underlying cause. Nevertheless, it is important to regularly monitor these nodules to ensure they do not continue to grow.
