The role of traditional healers along the cancer care continuum in Sub-Saharan Africa: a scoping review.

Abstract

Background: Traditional healers play a significant role in Sub-Saharan Africa's healthcare system, but little is known about their role across the cancer care continuum in this context. Given the prevalence of patients consulting healers, we aimed to elucidate their role and impact on cancer care delivery in Sub-Saharan Africa.

Methods: Following the PRISMA reporting standards, all research focused on the role of traditional healers in the cancer care continuum in sub-Saharan Africa was included in this scoping review. Data sources assessed include PubMed, Cochrane Library, Embase, and CINAHL Plus with Full Text, Scopus, Sociological Abstracts, African Journals Online, African Index Medicus, and Google Scholar. Studies that lacked perspectives on the healers' role, focused solely on the actual herbal medicines, were written in non-English language, were not primary research, or the full-text was unavailable were excluded. Two reviewers performed screening and data extraction for each article, confirmed by a third reviewer.

Results: One thousand four hundred seventy-one studies were identified, with 1437 screened and 191 full-texts reviewed. Of those, 158 were excluded, and 33 (comprising of 1564 healers) were included for final data extraction and analysis. Five studies (64 healers) showed their role in prevention, eleven (454 healers) in diagnosis, twenty-seven (1524 healers) in treatment, and two (25 healers) in palliative care in Sub-Saharan Africa. While some desired increased collaboration with the biomedical system and referred patients, others lacked trust and remained hesitant to provide referrals.

Conclusion: Results showed that traditional healers play an important role in cancer treatment. This provides an opportunity to leverage the skills of traditional healers to improve cancer outcomes, in a way that recognizes and respects local culture. Future research focused on improving the collaboration between traditional healers and the biomedical healthcare system may lead to strengthening the referral system and early detection and treatment of cancer.
