Cancer Prevalence: How Many People Have Cancer?
What is cancer prevalence?
Cancer prevalence is defined as the total number of people living with cancer at any point in time. It includes people diagnosed with cancer in the past as well those who were recently diagnosed.
Cancer prevalence is not a measure of how common a cancer is. This number is the cancer incidence, which is the number of people newly diagnosed with cancer in a given time period (usually a year).
Prevalence is affected both by the incidence of a cancer and by how long people normally live with the disease.
For example, lung cancer is the second most common cancer in both men and women, but lung cancer prevalence is not as high as that of some less common cancers. This is because people with lung cancer tend not to live as long after diagnosis.
The numbers
The numbers on the chart come from the US National Cancer Institute's Surveillance Epidemiology and End Results (SEER) database for the year 2007, the most recent year for which good estimates are available. These estimates are based on a sampling of the US population.
Numbers may not add up because they have been rounded to the nearest 1,000.
