Abstract

Cervical cancer if not detected and treated promptly can be lethal to females. In several advanced nations, the relevance of coordinated screening services has been implemented. Nevertheless, most developing nations have not implemented a nationwide screening and vaccination programme accessible to all women owing to inadequate screening and vaccination services coupled with vaccine scepticism, misconception concerning vaccination, and lack of awareness are causing an upsurge in Africa's cervical cancer cases. Cervical cancer could be greatly reduced if comprehensive screening services and HPV vaccination are implemented. In this review, we discussed the cervical cancer incidence in Africa, factors influencing the high rate of cervical cancer in Africa, screening and HPV vaccination programs and the potential intervention and recommendations to reduce the incident and mortality rates of cervical cancer in Africa. Also, we highlighted the disadvantages and advantages of widely accessible screening tests in Africa.
