Prevalence and Incidence of Follicular lymphoma
Follicular lymphoma: Rare Disease
Follicular lymphoma is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Follicular lymphoma, or a subtype of Follicular lymphoma,
affects less than 200,000 people in the US population.
Ophanet, who are a consortium of European partners,
currently defines a condition rare when if affects 1 person per 2,000.
They list Follicular lymphoma as a "rare disease".

About prevalence and incidence statistics:
The term 'prevalence' of Follicular lymphoma usually refers to the estimated population
of people who are managing Follicular lymphoma at any given time.
The term 'incidence' of Follicular lymphoma refers to the annual diagnosis rate,
or the number of new cases of Follicular 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.
