Statistics showing a signficiant decline in stomach cancer death rate in Japan are presented. The decline was most striking in cancer of the pylorus, compared with other anatomical sites, and in metropolitan areas, compared with rural areas. Dietary change, especially of milk and milk products, is a possible reason for the decline, although some of the decrease is attributed to the active nationwide programme of early detection of stomach cancer.
