How many people reported cancer of throat and lungs after exposure to construction fiberglass?

In my. Experience...None. Smoking, causes both; asbestos, not fiber glass, is associated with mesothelioma and lung cancer, but not throat or oral cancer.
Not many yet. In several studies fiberglass is not implicated as a cause of cancer, need more evidence , however few studies show some correlation due to some of the components used in fiberglass manufacture. Fda did not classify fiberglass dust as carcinogen.
