Viruses have been associated with cancer development cicoinas both animals and humans. Human Papilloma viruses HPV are related with the development of cervical cancer, considered the second more prevalent type of cancer in women worldwide.

In this review we describe the events responsible for the HPV-induced carcinogenesis. E6 and E7 oncoproteins are essential in the process of malignant transformation induced by HPV and involve many other factors such as the interaction of these proteins with cell cycle regulatory factors.

De esta manera los virus aprendieron a sobrevivir en un ambiente celular hostil. El significado de estos hallazgos no fue apreciado ya que las verrugas son hiperplasias benignas y no tumores malignos.

Este proceso dependienntes clasifica en cuatro fases secuenciales denominadas G1, G2, S y M. Un sistema inmune comprometido puede resultar en un incremento en la incidencia de tumores, como ha sido observado en individuos VIH positivos o en pacientes trasplantados que son tratados con inmunosupresores 15, 16, Se han identificado genotipos, de los cuales 40 son considerados de tipo genital.
