EBV has a well-established role in the pathogenesis of several cancers, including Burkitt's lymphoma, Hodgkin's lymphoma, and nasopharyngeal carcinoma. In these cancers, EBV contributes to the transformation and proliferation of infected cells. For instance, in Burkitt's lymphoma, EBV infection often accompanies chromosomal translocations involving the MYC oncogene, leading to uncontrolled cell growth.
