Many people know about the link between HPV and cervical cancer, but did you know that HPV also causes at least five other cancers? We also discuss steps that you can take to protect yourself and your loved ones from HPV-associated cancer. Finally, we provide a timeline of HPV and cancer to show you how far we have come, and how far we still have to go. There are about 16 high-risk types that have been identified, and there are over different types of HPV overall.

Data on carcinogenicity of human papillomavirus HPV types in the anus are needed to inform anal cancer prevention through vaccination and screening. This is particularly the case for people infected with HIV, who are at an increased risk of anal cancer. Eligible studies reported type-specific HPV prevalence by strata of cytopathological or histopathological anal diagnosis, sex, and HIV status. Data requests were made to authors when necessary. We did a meta-analysis of type-specific HPV prevalence across the full spectrum of anal diagnoses, from normal cytology to anal cancer. We assessed the main outcome of type-specific HPV prevalence ratios [PR], calculated across strata of anal diagnoses, gender, or HIV status, by use of generalised linear models. HPV16 positivity increased even between high-grade lesions and anal cancer, whereas other high-risk HPV types accounted for high proportions of low-grade or high-grade lesions but their prevalence decreased in anal cancer. Large meta-analyses of type-specific prevalence across the full spectrum of human papillomavirus HPV -related disease have been used to characterise carcinogenicity of individual HPV types in the cervix, both in women who are HIV negative and those who are HIV positive.
To investigate the clinical and prognostic aspects of anal cancers associated with the presence, as well as the genotypic distribution of human papillomavirus HPV. The data analysis was done using descriptive univariate statistics, and the survival curves were made using the Kaplan—Meier and log-rank methods. Female patients had a higher prevalence of HPV. Multiple infections were detected in The most prevalent genotypes were HPVs 16, 33, and The overall survival at 60 months was Survival was not influenced by the presence of HPV.
Anal cancer is the term for abnormal cell growth in the anal area or the anal canal. The anal canal connects the anus the opening to the rectum. This passage is about inches long. It is the part of the body that excretes solid waste bowel movements, feces. The disease also is called carcinoma of the anal canal. The anus is the end of the digestive system. The anus is made up of tissue from the skin and from the intestine. While not the only type of anal cancer, the most common type is squamous cell carcinoma SCC , a type of skin cancer.
