この中に、All forms of asbestos are carcinogenic to humans, and may cause mesothelioma and cancer of the lung, larynx and ovary. と書いてありますが、喉頭癌、卵巣癌については、どの程度のコンセンサスがあるのでしょうか？
Laryngeal cancer has been considered in two case-control studies, resulting in risk ratios of 2.4 and 2.3 that relate to shipyard work and unspecified exposure, respectively. A cohort study of insulation workers showed a relative risk of 1 .9, based on ni ne cases. A case series indicated a high frequency of exposure to asbestos, especially in low-grade smokers. A risk ratio of 3.2 for laryngeal cancer was reported among chrysotile miners in an area with generally high incidenceo, but no increased risk was seen in a cohort of workers with exposure to crocidolite. Two correlation studies have also indicated a relationship between laryngeal cancer and exposure to asbestos.
Sorne excess of ovarian cancer has been reported in two studies but not in another; exposure to crocidolite was probably more predominant in the studies that showed excesses.
