 This study found that high-risk human papillomaviruses, HPV, and Epstein-Bavirus, EBV, are commonly present in breast cancer tissues from Katari women with a co-prevalence of 47%. The presence of HPV was associated with triple negative breast cancer, TNBC, while the presence of EBV did not correlate with any breast cancer subgroup. Additionally, the co-presence of HPV and EBV were significantly associated with tumor grade and stage. These findings suggest that HPV and EBV may cooperate to promote a more aggressive tumor phenotype in breast carcinogenesis, and further investigations are needed to understand the underlying mechanisms.
