As an extension of an earlier study covering the 8-year period 1965-71 (t1), the incidence of cancer in black gold miners over a second 8-year period, 1972-79 (t2) has been investigated. The population again totalled 2.9 million man-years of employment, an average of 363,800 men per year. Of the 903 cancers found in t2, primary liver cancer accounted for(More)
This investigation was carried out by questionnaire to parents of SIDS cases and two controls for each case and aimed to follow up the fact that Tasmania has been shown to have an unusually high rate of this cause of death. Both chi 2 and relative risk calculations were employed. The high rate of SIDS of the 1970s has been confirmed in this series in the(More)
The pattern of cancer in African gold miners over the 8-year period 1964-71, comprising 2,926,461 man-years of employment was studied. Of the 1344 cancers found, primary liver cancer accounted for 52-8%, oesophageal cancer 12-1%, cancer of the respiratory system 5-4% and cancer of the bladder 4-8%. Analysis of the spatial distribution of these four cancers,(More)
The discovery of commercial quantities of gold in the former Transvaal of South Africa in 18961 came twenty years after the exploitation of diamonds in the northen Cape. Labour practices followed the existing migratory pattern for domestic and foreign labour in industry, a pattern which exists to this day. Gold miners, like diamond miners, were accommodated(More)
The geographical distribution of lung and stomach cancer among three races in South Africa (Whites, Coloureds and Asians) has been investigated for the years 1968-1972, and the patterns of the occurrence of cases of cancer have been tested stochastically and mapped both separately and together. Information was not available for the Black population.(More)
The geographical distributions of six major causes of cancer mortality in South Africa have been analysed for three population groups: White, Coloured and Asian. Because of the lack of comparable data, the majority Black population is not included. Geographical patterns are compared and discussed in the light of findings from other countries. In several(More)
