MYC and diffuse large B-cell lymphoma: The MYC proto‐oncogene and its product, the MYC transcription factor, have a central role in cellular growth control and are widely deregulated in many cancers, where they contribute to many facets of malignant transformation (Hsieh et al, 2015; Kress et al, 2015; Dhanasekaran et al, 2022) and are generally recognized as adverse prognostic factors (Kalkat et al, 2017; Donati & Amati, 2022), as best exemplified by diffuse large B‐cell lymphoma (DLBCL; Li et al, 2018; Bisso et al, 2019; Rosenwald et al, 2019).
