HPV is believed to cause cancer by integrating its genome into nuclear DNA. Some of the early genes expressed by HPV, such as E6 and E7, act as oncogenes that promote tumor growth and malignant transformation. [17] HPV genome integration can also cause carcinogenesis by promoting genomic instability associated with alterations in DNA copy ...
