The majority of World Health Organization and U.S. government scientists who voted to list fibrous glass believed that injecting or implanting fibers in or near the lung gives a more accurate picture of the likelihood of human cancer. This contention is strongly disputed by Eugene McConnell, who co-chaired the WHO carcinogens committee in 1988 but has since become one of the foremost critics of the implantation studies. He says implantation delivers unrealistically high doses of fiber to the test animals. When a fibrous mass is implanted, he says, "the minute it gets there, the cells are attracted to it. They wrap around a foreign body, and now it can't dissolve. So the [cancerous] lesion you produce in the peritoneal cavity has no rhyme or reason in the body. It could never be produced" except by injection. In real-life settings, he says, "when you are exposed to fibers, it is a given level over a lifetime. You don't get one big blast."

Resume of article, dont work in a fiberglass factory and dont smoke.

Hopefully the OP wont be more than a few years in the attic.
