Which lymphoma is a heterogeneous group of lymphoid cancers with variable aggressiveness and unpredictable spread?

• A. Non-Hodgkin lymphoma
• B. Hodgkin lymphoma
• C. Lymphoid leukemia
• D. Melanoma

Answer: (A)

Lymphoid cancers can vary widely in how they grow and spread. Non-Hodgkin lymphoma is a broad category that includes many subtypes with different behaviors—from slow-growing forms to very aggressive ones. This leads to a wide range in how quickly the disease progresses and where it may spread, making the course of the illness often unpredictable. Hodgkin lymphoma, while serious, is a more defined and uniform disease with characteristic features and a relatively more predictable spread pattern. Lymphoid leukemia involves cancer of the blood and bone marrow rather than forming the varied solid lymphoid tumors seen in lymphomas. Melanoma is a skin cancer not related to lymphoid tissue.
