title: Etiology of lung cancer at the Gejiu tin mine, China.
abstract: There were 1,724 lung cancer cases registered at the Yunnan Tin Corporation in the period 1954-1986, of which 90% had a history of working underground. Previous exposure to radon, and radon daughters and arsenic is considered to be responsible for the high incidence of lung cancer in these miners. Arsenic may come from inhalation of arsenic-containing ore dust or other environmental arsenic pollution. It appears that radon exposure accounts to a greater extent than arsenic for the increase of lung cancer in these miners. Pathological study was made of 100 surgically resected lung cancer specimens. In this way the distribution and composition of dust retention was determined in relation to peripheral lung cancer.
