Non-Hodgkin lymphoma, is a cancer that starts in cells called lymphocytes, which are part of the body's immune system. Lymphocytes are in the lymph nodes and other lymphoid tissues. The risk of developing NHL up to the age of 74 was 1 in 102 for women and 1 in 80 for men, and was higher in NI than in RoI for both males and females. At the end of 2008, 1,255 females and 1,607 males aged under 65, and 1,477 females and 1,266 males aged 65 and over, were alive up to 15 years after their NHL diagnosis.
Examination in patients with low-grade lymphomas may demonstrate peripheral adenopathy, splenomegaly, and hepatomegaly.
Intermediate- and high-grade lymphomas may result in the following examination findings:
• Rapidly growing and bulky lymphadenopathy
• Large abdominal mass: Usually in Burkitt lymphoma
