The first diagram shows the worldwide share of the population with cancer. The United States and Canada lead the pack with the highest cancer rates.
The second diagram shows the cancer rates for a few selected countries. Japan, Australia, and New Zealand are in the middle of the pack with cancer rates of 2.5 % to 3.0 %.
I find it interesting that the cancer rate in China was fairly stable at 0.8 % until about 2006. The cancer rate then increased to 1.45 %.
