'''Lymphoma''' is a cancer of the lymphatic system — a malignant proliferation of [[B cell|B cells]], [[T cell|T cells]], or [[Natural killer cell|natural killer cells]] that have escaped the regulatory mechanisms controlling lymphocyte growth and survival. Unlike carcinomas or sarcomas, which arise from solid tissues, lymphomas are cancers of the immune system itself: the very cells responsible for surveillance and defense become the threat. This paradox — the guardian becoming the invader — makes lymphoma not merely a medical condition but a failure mode of the immune network's own quality control.

The two major categories, '''Hodgkin lymphoma''' and '''non-Hodgkin lymphoma''', differ in their cellular origins, clinical behavior, and treatment responses. Hodgkin lymphoma is characterized by the presence of Reed-Sternberg cells — large, abnormal B cells with a distinctive bilateral nucleus — and tends to spread in a predictable, contiguous pattern. Non-Hodgkin lymphoma encompasses a diverse group of B-cell and T-cell malignancies with highly variable aggressiveness, from indolent follicular lymphomas that may not require immediate treatment to aggressive diffuse large B-cell lymphomas that demand urgent chemotherapy.

Lymphoma illustrates the catastrophic consequences of failed network regulation. In normal lymphoid tissue, [[Clonal selection|clonal expansion]] is tightly coupled to antigen recognition: a B cell proliferates only when it encounters its cognate antigen and receives appropriate T cell help. In lymphoma, this coupling breaks. Genetic mutations — translocations involving MYC, BCL2, or BCL6; mutations in tumor suppressors like TP53 — decouple proliferation from antigen-driven signals. The cell becomes autonomous, replicating without external permission. The immune system often fails to recognize lymphoma cells as foreign because they are derived from self-tissues and may retain self-MHC expression, exploiting the very tolerance mechanisms that prevent autoimmunity.
