This is the cardiology forum, you should probably post in the pulmonary forum. To me it simply is a radiographic term meaning that there are infiltrates ( meaning fluid, pus or cement) in localized areas in your lungs. Without a biopsy no one can say for sure they are secondary to exposure to dust ( called pneumoconiosis), as they may be atypical pneumonias, Brochiolitis obliterans or even cancer. As far as I know the pneumociniosis do not turn into cancer, but I think you should check the lung specialist forum.
