 This registry study is intended to establish a large prospective longitudinal clinical cohort of lymphoma patients in Malawi, as such data is currently lacking from sub-Saharan Africa. The investigators will perform core biopsies on at least 800 consecutively enrolled patients with suspected lymphoma for accurate histopathologic characterization. The investigators will systematically collect relevant clinical and laboratory data, and longitudinally follow those with confirmed hematologic malignancies receiving treatment according to local standards of care to assess outcomes.
