Abstract

Pathological observation was made in 100 surgically resected lung cancers of Yunnan tin miners: peripheral type 44 including 9 scar cancers; central type 56, 27 of whom were early lung cancer, with limited initial loci in a well defined area. On the basis of dust retention in original sites of lung cancer and results of X-ray microanalysis, a scheme for calculating the relative probability of causation is formulated. The result of calculation shows that the contribution of exposure to radon daughters is about 7 times that of ore dust retention in the etiology of Yunnan tin miner's lung cancer.
