Overview
Cervical cancer is caused by an infection with Human papillomavirus, which is transmitted by skin to skin contact and sexually. Only high risk strains of HPV are causing cervical cancer, having multiple sexual partner is a risk factor for infecting with HPV.
Causes
- Human papillomavirus is main cause of cervical cancer, only high-risk HPV types are the ones can affect squamous epithelium of cervix and cause cancer.
- HPV is a small, nonenveloped DNA virus, 55 nm in diameter, transmits primarily by skin to skin contact. [1]
- High risk strains include types 16, 18, 31, 33, 34, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, and 70.
- HPV oncogenes interfere with cell cycle control and causes abnormal growth of squamous cells in epithelium of cervix.
- The assosiciation between HPV infection and glandular type of cervical neoplasia is less strong than that of squamous carcinoma of cervix.
