Mid-Sized Barns. Mid-Sized Barns-from 7 to 15 stalls. Some mid-sized horse barns are private, but often a mid-sized barn has to work for a living. . . as a boarding facility, a training barn, or the center of a breeding operation.
This can cause scarring. Asbestosis, caused by exposure to asbestos, causes scarring and might lead to lung cancer. Silicosis, caused by the inhalation of silica dust, will also cause scarring in the lungs. Mining of gold, lead, copper, zinc, iron and anthracite can result in silicosis if the proper precautions are not taken.
In the PLCO trial, pulmonary scarring was associated with increased lung cancer risk but only for cancer in the same lung where scarring was present, suggesting that scarring is associated with a localized process of tissue damage and repair that may contribute to cancer development.
