Talc-treated rice and Japanese stomach cancer

Science. 1971 Sep 17;173(4002):1141-2. doi: 10.1126/science.173.4002.1141.


The Japanese prefer talc-dusted rice in their diet. The incidence of stomach cancer in Japan is unusually high. Most talc has some asbestos contaminants. Epidemiologic evidence is presented that the asbestos-contaminated talc on rice in the diet is the carcinogen or cocarcinogen responsible for the high incidence of Japanese stomach cancer.
