A new study from the International Agency for Research on Cancer (IARC) and its partners explores the link between levels of Epstein–Barr virus (EBV) capsid antigen (VCA-IgA) antibodies, which are produced in response to EBV infection, and cancer risk.
The findings, published in Nature Communications, reveal a significant association between the presence of these antibodies and an increased risk of multiple cancer types. Individuals who tested positive for EBV VCA-IgA antibodies were found to have a higher risk of developing cancers such as lung cancer, liver cancer, nasopharyngeal carcinoma, and lymphoma; the association with nasopharyngeal carcinoma was the strongest.
