Approximately 64,000 Americans will be diagnosed with lymphoma in 2005, the vast majority (about 90%) will have non-Hodgkin lymphoma.
Of these cases of non-Hodgkin lymphoma, only 2% will be diagnosed in children. The incidence of non-Hodgkin lymphoma increases with age.
Of cases of Hodgkin lymphoma, only 12 % will be diagnosed in children, and most of these are adolescents.
In general, lymphomas are more common in males than in females and more common in Caucasians than African-Americans. Lymphomas are the third most common form of cancer in children (the most common is leukemia, followed by tumors of the central nervous system).
