Do you believe that absestos can cause a lung nodule?

Yes and No: Asbestos can cause scarring of the lungs(Plaques and fibrosis). In that regard a lung nodule could develop , either due to scar or due to lung Cancer. Most patients with lung nodules do not have asbestosis as the cause. So it would be low on my list of causes for a lung nodule..

Yes: is the short answer. Asbestos can cause several different changes to the chest and lung fields. Pulmonary nodules are just one example. Pleural disease including plaques and calcification as well as mesothelioma are side affects of asbestos. Lung cancer is also a problem. Don't ignore this nodule. Talk to your doctor.
