Lymphoma is a type of cancer that starts in the lymphatic system, which is part of your body’s immune system. It usually involves abnormal growth of white blood cells called lymphocytes.
From 'lymph,' the clear fluid that circulates in the lymphatic system, plus the medical suffix '-oma,' meaning 'tumor' or 'swelling.' The term labels tumors arising from lymph-related tissues.
Your lymph system is like a quiet parallel highway system for immune cells, running alongside your blood vessels. When lymphoma happens, it’s as if one class of traveling defenders starts multiplying without limits, turning defense into a new kind of threat.
