Answer by  Amie1084 (181)

Lung nodules have many different causes. While there are lung nodules that are created by cancerous cells, the benign nodules can be caused by tuberculosis, immune disorders and by fungal infections. In fact, lung nodules may occur in people that live near the Ohio, Mississippi and Missouri river valleys due to increased occurrences of fungal infections in the area.
