Is fiber insulation causes cancer?

Not 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.

No: Epidemiologic studies in which people with different diagnoses try to remember different things that have happened in their lives generate a huge amount of junk=findings that politicians and scare-mongers misuse. Unlike asbestos, it makes no sense biologically that fiberglass would be a real cancer risk.
