Example 172,570 people in America were diagnosed with lung cancer in 2005, a year in which there were approximately 290,000,000 Americans, yielding an absolute risk of 1:1,680 of being diagnosed with lung cancer. Adding context—e.g., age, smoking history, industrial exposure, etc.—is used to define a person’s relative risk of suffering a particular condition.
