PREVALÊNCIA DE PAPILOMA VÍRUS HUMANO (HPV) EM CÂNCER DE COLO DE ÚTERO EM PORTADORAS ASSINTOMÁTICAS: UM ESTUDO DE CASO

Abstract

The cancer usually appears as a consequence
of intrinsic factors (hormones, immune condictions and
altered gene mutation) or extrinsic factors (quimic
substances, radiation and viruses). The mortality rate is
high as a result of this pathology, since the same is
greatest in the developing countries like Brazil. Human
papillomavirus (HPV) is present in 95% of cases of cancer
of the cervix and transmitted sexually. It presents more
than 100 differents types divided into three groups
according to the lesion (low, medium and high grade). Of
these, types 16 and 18 are frequently found in cervical
intraepithelial neoplasia cervical. Several risk factors are
associated with cancer of the cervix such as sexual habits
and food, immunosuppression use of oral contraceptives,
smoking and pregnancy. The virus can be detected by
various methods, but the most commonly used method is
the Pap smear.
