Answer

Bone marrow aspiration and biopsy is performed as part of the staging process to help rule out involvement with lymphoma. Bilateral iliac crest bone marrow biopsies should also be performed as part of the staging.

Lymph node biopsy is required to establish a definitive diagnosis of non-Hodgkin lymphoma (NHL); this should be an excisional biopsy rather than a needle biopsy, because nodal architecture is often difficult to assess when small amounts of tissue are used.
