| Abstract:: |
| Using two-stage clonal expansion model with data-base provided by Lubin, WD Hazelton et al indicated the high risk of arsenic, but not radon, in the etiology of Yunnan tin miner's lung cancer. The author of this review iterated the problems in the data-base of Lubin, and considered that it may result in low estimate for the risk of radon in paper of Hazelton et al. Attributable risk was estimated by them with changing exposure patterns of each individual, but the efficacy of this two-stage model will be violated by the invariability of appointed radon/arsenic exposures. Risk comparison was used to distinguish the contribution from radon/arsenic, which was hampered by the high correlation between their joint exposures. As Lubin, Hazelton et al neglected the confounding from environmental arsenic pollution in early years. From all of above, their viewpoint is worth to be deliberated. |
