What is a key feature of non-Hodgkin's lymphoma?

• A. Characterized by Reed-Sternberg cells
• B. Composed mainly of aggressive cancers
• C. A diverse group of cancers in immune system cells
• D. Only occurs in B lymphocytes

Answer: (C)

Non-Hodgkin's lymphoma is indeed characterized as a diverse group of cancers that originate in the immune system cells, specifically the lymphocytes. This diversity means that it includes various types of lymphoma, which can behave very differently in terms of their aggressiveness, treatment response, and outcomes. Non-Hodgkin's lymphoma can arise from either B cells or T cells, making it a broader category than lymphomas that primarily involve one type of lymphocyte. The range of non-Hodgkin's lymphoma includes both indolent (slow-growing) and aggressive forms, thereby highlighting the importance of its heterogeneous nature. This variation can influence treatment strategies and prognostic outcomes for individual patients. In contrast, other options are not representative of non-Hodgkin's lymphoma. For example, the presence of Reed-Sternberg cells is specifically associated with Hodgkin's lymphoma, not non-Hodgkin's. The statement regarding the composition of primarily aggressive cancers does not accurately reflect the range of indolent and aggressive forms seen in non-Hodgkin's lymphoma. Additionally, stating that it only occurs in B lymphocytes is overly restrictive, as non-Hodgkin's lymphoma can also originate from T cells, further emphasizing its diversity.
