About statistics:

This page presents a variety of statistics about Non-Hodgkin's Lymphoma. The term 'prevalence' of Non-Hodgkin's Lymphoma usually refers to the estimated population of people who are managing Non-Hodgkin's Lymphoma at any given time. The term 'incidence' of Non-Hodgkin's Lymphoma refers to the annual diagnosis rate, or the number of new cases of Non-Hodgkin's Lymphoma diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
