AB  - Cervical cancer remains a leading cause of cancer-related morbidity and mortality among women in sub-Saharan Africa despite being largely preventable through vaccination, screening, and early treatment. In Kenya, screening uptake is especially low among pastoralist and other marginalized women because of limited awareness, sociocultural barriers, weak health communication, and poor access to preventive services, and conventional biomedical communication often overlooks indigenous knowledge systems and communal decision-making. This study examined the influence of an Afrocentric Two-Step Flow communication strategy delivered by Community Health Promoters on cervical cancer knowledge and screening uptake among nomadic pastoralist women in Isiolo County, Kenya.
