In epidemiology, "incidence rate" is a measure of how many people within a given population will develop a disease or other condition during a specified period of time. It is, essentially, a measurement of risk.
The National Cancer Institute estimates that 65,980 new cases of Non-Hodgkin's Lymphoma will be diagnosed in 2009. This represents 89% of all lymphomas, and 4% of all cancers diagnosed. It is the seventh most common cancer in the United States.
Lymphoma is a well-researched subject and many statistics are published annually. For the most up-to-date and complete statistical information on lymphoma, please see the resources listed at the bottom of the page.
