The Decline in Mesothelioma Rates Continues
The US Cancer Statistics reflect data reported by the SEER registries and the National Program of Cancer Registries. Combined, these two programs provide 100% coverage of cancer incidence in the US since 2001. The statistics show that the actual yearly counts of pleural mesothelioma cases in men have remained relatively flat. But, as the population…
Risk of Mesothelioma in the North Carolina Textile Cohort Quantified
Loomis, et al. (2009) described the incidence of mesothelioma and lung cancer in four North Carolina textile plants. In the plants denoted as plant 1 and plant 2, there were no mesotheliomas or pleural cancers. There were three pleural cancers in plant 3. In plant 4, the authors reported four mesotheliomas and one pleural cancer among…
Are Relative Potency Analyses Proof That Chrysotile Has Some Potency for Mesothelioma?
Many researchers have published analyses of the relative potency for the commercial asbestos fiber types to cause mesothelioma. Hodgson & Darnton (2000) is often cited for estimating the potency of crocidolite to amosite to chrysotile as 500: 100: 1. Berman & Crump (2008) estimate the amphiboles were more than 200 times more potent than chrysotile. More recently, Garabrant & Pastula…
