Molecular virology and epidemiology of human papillomavirus and cervical cancer.

Introduction In 1994, an estimated 55,000 women in the United States will be diagnosed with carcinoma in situ of the cervix, with an additional 15,000 invasive cases expected. An estimated 4600 women died from this disease in 1994, despite remarkable progress made in screening (1). Regarding extent of disease among women with invasive cancer in the United States from 1983 to 1987, 48% of tumors...

Molecular epidemiology of Human Papillomaviruses in breast cancer, Golestan province of Iran

Abstract Background and objectives: Breast cancer is the most prevalent one in women. Some of the common causative factors are genetic background, nutritional and environmental factors. Viruses are believed as a risk factor in this cancer, too. Recent studies reported that Human Papillomaviruses can be one of the possible risk factors of breast cancer. This study focused on investigation of the...

The epidemiology of human papillomavirus infections.

Infection with oncogenic human papillomavirus (HPV) types is a necessary cause of cervical cancer, the second most frequently occurring cancer in women worldwide. Rates of acquisition of HPV are high, particularly among sexually active young adults. Reported estimates of incident HPV infection among initially negative women have reached as high as 60% over a 5-year follow-up period. In this art...

Epidemiology of Anogenital Human Papillomavirus Infections

The epidemiology of genital human papillomavirus infection.

Clinical and subclinical human papillomavirus (HPV) infections are the most common sexually transmitted infections in the world, and most sexually-active individuals are likely to be exposed to HPV infection during their lifetimes. More than 40 genotypes of HPV infect the epithelial lining of the anogenital tract and other mucosal areas of the body; of these, 13-18 types are considered to be hi...
