Occupational Exposure to Rock Wool and Glass Wool and Risk of Cancers of the Lung and the Head and Neck: A Systematic Review and Meta-Analysis

Despite a small elevation in RR for lung cancer among MMVF production workers, the lack of excess risk among end users, the absence of any dose-risk relation, the likelihood of detection bias, and the potential for residual confounding by smoking and asbestos exposure argue against a carcinogenic effect of MMVF, RW, or GW at this time. Similar conclusions apply to HN cancer risk among workers exposed to MMVF.
