The Cancer Pattern in African Gold Miners [PDF]

open access: yesBritish Journal of Cancer, 1971
The incidence of cancer among the African workers on the gold mines of South Africa has been studied for the period 1964-68. Considering the degree of selection to which they are subjected, the crude cancer rate was unexpectedly high.The most common cancers were those of the liver, the oesophagus, the respiratory system and the bladder.
