Spread of cancer in percentages for different countries of the world.

In 2020, there were an estimated 18.1 million cases of cancer worldwide, according to the World Cancer Research Fund. Of those cases, the United States had the fourth highest number of new diagnoses, with 362 cases per 100,000 people.
