Human Papilloma Virus (HPV) 20 Low & High Risk Subtypes LIS Code: HPV20

Human Papillomavirus (HPV) and Cervical Cancer

Persistent infection with human papillomavirus (HPV) is the primary cause of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN). More than 99% of cervical cancer cases globally are linked to HPV infection, making it a critical factor in cervical disease development.

HPV Structure and Types

HPV is a small, non-enveloped, double-stranded DNA virus with a genome of approximately 8,000 nucleotides. There are over 118 known types of HPV, with around 40 types capable of infecting the human anogenital mucosa. These types vary significantly in their potential to cause cancer.

HPV Risk Classification

HPV types are grouped based on their oncogenic (cancer-causing) potential:

High-Risk HPV Types
These types are strongly associated with the development of cervical cancer and other anogenital malignancies:

HPV 16, 18, 31, 33, 35, 39

HPV 45, 51, 52, 56, 58

HPV 59, 66, 68, 73, 82

Low-Risk HPV Types
These types are typically linked to benign conditions, such as genital warts, and have minimal risk of progressing to cancer:

HPV 6, 11, 40, 42, 43, 44

HPV 54, 61, 70, 72, 81

HPV Testing and Cervical Cancer Screening in Slough and Surrounding Areas

Private HPV testing and cervical cancer screening services are available in Slough, Windsor, Langley, Burnham, and Maidenhead. Identifying high-risk HPV strains through regular screening plays a vital role in the early detection and prevention of cervical cancer. Early intervention and monitoring of HPV infections significantly reduce the risk of disease progression, making routine testing an essential component of women's health care in the local community.
