B-cell lymphoma refers to a type of cancer that develops in the lymphatic system from malignant B-cells. There are several synonyms for B-cell lymphoma, including non-Hodgkin's lymphoma, B-cell neoplasm, lymphocytic lymphoma, and B-cell lymphoproliferative disorder. Non-Hodgkin's lymphoma is a broad category of lymphomas that can affect both B and T cells. B-cell neoplasm describes any abnormal proliferation of B-cells, whether benign or cancerous. Lymphocytic lymphoma specifically refers to cancerous B-cells that primarily affect the lymph nodes, while B-cell lymphoproliferative disorder is a rare disorder in which B-cells grow uncontrollably, potentially leading to lymphoma.
