Australia has one of the highest rates of bowel cancer in the world, though the United States is high as well. In 2017, bowel cancer was the second-most-common cancer in Australia and rates are increasing in people under 50.
The World Health Organization puts the cumulative risk of developing collector cancer at 4.1 percent in Australia and New Zealand, compared to 2.96 percent in North America, which is still comparatively high in international rankings.
