About this Video
In this video, Hans Rosling shows that stomach cancer is rare in the poorest countries and the rate of this cancer reach a peak in middle income countries. When countries get still richer the frequency falls. This is in sharp contrast to breast and colon cancer that tend to increase in frequency as countries get richer and richer. The rate of stomach cancer has been especially high in Japan and China. In Japan, wide-spread screening programs using the Japanese endoscopy invention have contributed to reduced death rate in this cancer.
Having seen the video you can look yourself in Gapminder World where the cancer data from IARC (International Agency for research on Cancer) is displayed as moving bubbles.
