CERVICAL CANCER AND ITS AETIOLOGY IN SUB-SAHARAN AFRICA: A LITERATURE REVIEW
Abstract
Cervical cancer represents a huge burden of non-infectious disease globally. It is the second commonest cancer in the female. There are over half a million deaths recorded every year as result of cervical cancer. The aetiological agent implicated in this disease is the human Papillomavirus. The high-risk human papillomavirus has been mostly implicated. The commonest high-risk human papillomavirus implicated in cervical cancer worldwide is type 16 and 18. The viral infection of the uterine cervical epithelium initially causes the development of precancerous lesions referred to as cervical intraepithelial lesions/squamous intraepithelial lesions which take many years to progress into cancer. The Papanicoulao smear test done for the screening of precancerous cervical lesions has been known to be effective in preventing the disease. The commonest types of cervical cancer are the cervical squamous cell carcinoma and adenocarcinoma.
