Cervical dysplasia is an abnormal change in the cells of the cervix in the uterus. Early changes, called low-grade lesions by doctors, may persist and develop into high-grade lesions that can lead to cervical cancer. Mildly abnormal cervical cells will usually clear up on their own. Both cervical dysplasia and cervical cancer can be best treated effectively when they are caught early. A sexually transmitted virus called HPV human papillomavirus causes most cervical dysplasia and all cervical cancers. Cervical dysplasia is common in HIV-positive people who have a cervix.

Human papillomavirus (HPV) infection and the multi-stage carcinogenesis of cervical cancer

This short review outlines our understanding of cervical cancer precursors, concentrating on the central etiologic role of persistent human papillomavirus HPV infection. The stages of cervical carcinogenesis are better understood than for most other major cancers, providing a successful cancer etiology and prevention model. The association of risk with sexual behavior has been posited since the mids but the central causal role of human papillomavirus HPV infection was identified just 35 years ago 1. Thus, the important preventive impact of cervical cytologic screening Papanicolaou tests in the second half of the twentieth century preceded and even advanced etiologic understanding. The accessibility of the cervix for population-wide tissue sampling, the delimited ring of tissue at risk the cervical transformation zone , and the uniform causal pathway centered on HPV infection, fostered the last few decades of productive interdisciplinary studies and improved preventive strategies 2. The cervix is the lower third of the uterus, projecting into the anterior aspect of the vagina; with regard to carcinogenesis, it can be viewed topologically as a two-dimensional ring of epithelium. The cervical transformation zone is an area of metaplastic tissue between the squamous epithelium of the vagina and the glandular tissue of the endocervical canal.

Vulvar Cancer

Vulvar cancer is a rare type of cancer. It forms in a woman's external genitals, called the vulva. The cancer usually grows slowly over several years. First, precancerous cells grow on vulvar skin.
There are many types of HPV. This is a very common infection that usually presents with no symptoms. However, without treatment, some types of HPV could cause cancer. Prevention is, therefore, very important. HPV infections usually clear from the body within 2 years.
