About 75%&#x2010;85% of these cases occur in low-income countries, with 23% specifically in Africa (as reported by the World Health Organization [WHO]). The incidence and mortality rates of cervical cancer are 2-3 times higher in low-income countries compared to high-income countries [<xref ref-type="bibr" rid="ref2">2</xref>].</p><p>Cervical cancer ranks as the second leading cause of cancer-related death globally [<xref ref-type="bibr" rid="ref3">3</xref>]. In 2025, studies from Africa showed that cervical cancer screening prevalence differs significantly between high-income countries (84%) and low- and middle-income countries (15%) [<xref ref-type="bibr" rid="ref4">4</xref>]. Also, in Africa, more than 53% of cervical cancer cases are identified at an advanced stage (stage III-IV) [<xref ref-type="bibr" rid="ref5">5</xref>].</p><p>Cervical cancer is &#x201C;a malignant tumor that forms when the cells in the tissue surrounding the cervix grow and multiply uncontrollably by passing the normal process of cell division&#x201D; [<xref ref-type="bibr" rid="ref6">6</xref>]. Effective early screening has been shown to reduce cervical cancer incidence by up to 80% and prevent more than 40% of new cases [<xref ref-type="bibr" rid="ref2">2</xref>,<xref ref-type="bibr" rid="ref7">7</xref>].</p><p>With an average cure rate of 80%, radiation therapy effectively treats cervical cancer in its early stages [<xref ref-type="bibr" rid="ref8">8</xref>]. However, the practice of early screening, before the disease reaches an advanced stage, continues to be a major problem in many parts of Africa [<xref ref-type="bibr" rid="ref5">5</xref>].</p><p>Despite the implementation of screening initiatives and the introduction of the human papillomavirus (HPV) vaccine, cervical cancer remains a significant public health concern in Africa [<xref ref-type="bibr" rid="ref9">9</xref>].</p><p>Early detection and timely treatment of cervical cancer are crucial [<xref ref-type="bibr" rid="ref10">10</xref>]. The HPV has more than 100 serotypes, but the HPV vaccine targets only 9 of them [<xref ref-type="bibr" rid="ref11">11</xref>]. Also, early screening is a key approach to achieving 1 of the 3 WHO 90-70-90 pillars: &#x201C;90% of girls fully vaccinated against HPV, 70% of women screened by age 35 and 45 with a high-performance test, and 90% of women with precancerous lesions receiving treatment&#x201D; [<xref ref-type="bibr" rid="ref12">12</xref>,<xref ref-type="bibr" rid="ref12">12</xref>].</p><p>Therefore, early screening is essential to enhance the probability of early diagnosis and treatment. Early screening is guaranteed to identify precancerous lesions and cancer before symptoms appear, which is the goal of screening, and enhances the chances of successful treatment and reduces maternal mortality [<xref ref-type="bibr" rid="ref12">12</xref>-<xref ref-type="bibr" rid="ref14">14</xref>].</p><p>However, studies show that screening in Africa is conducted at less than 70% of the WHO target [<xref ref-type="bibr" rid="ref15">15</xref>]. This is due to a perceived lack of expertise, limited knowledge about cervical cancer, inadequate screening tools and supplies, and insufficient funding [<xref ref-type="bibr" rid="ref5">5</xref>,<xref ref-type="bibr" rid="ref16">16</xref>,<xref ref-type="bibr" rid="ref17">17</xref>]. In the recent study, the prevalence of precancerous cervical lesions and cancer is relatively high, at 18% and 14%, respectively [<xref ref-type="bibr" rid="ref18">18</xref>].</p><p>According to previous studies conducted in Africa, age, education level, employment status, wealth index, place of residence, and access to health care facilities were common predictors of cervical cancer screening among women of reproductive age [<xref ref-type="bibr" rid="ref19">19</xref>-<xref ref-type="bibr" rid="ref22">22</xref>].</p><p>Although studies have been conducted in African countries, they were limited to small sample sizes and single countries, lacking representativeness. This study, however, is representative, with a large dataset covering multiple countries, providing reliable evidence for policymakers and researchers to inform interventions.</p><p>The health care system produces vast amounts of data that must be analyzed to support effective decision-making. As the volume and complexity of this data grow, relying on traditional analytical methods without the aid of machine learning is becoming increasingly impractical.</p><p>A key strength of machine learning is its ability to handle big datasets while delivering reliable performance metrics.

However, according to this study, a small percentage of women were screened for cervical cancer in Kenya (14.22%), Mozambique (12.76%), Tanzania (12.20%), and Ghana (7.27%).

Women who do not have information about their health status are less likely to undergo cervical cancer screening because a lack of awareness reduces their understanding of risk, engagement with health care, and motivation to seek preventive services.</p><p>This study showed that women who had their first sexual intercourse before the age of 30 years had an increased cervical screening status. This is in line with studies conducted in East Gojjam Zone, Ethiopia, Africa, and Nigeria [<xref ref-type="bibr" rid="ref54">54</xref>-<xref ref-type="bibr" rid="ref56">56</xref>]. A possible explanation for this is that early sexual activity is associated with a higher likelihood of STIs, which in turn leads to more frequent visits to health facilities due to increased awareness of cervical cancer risk.</p><p>In addition, women in this age group are more educated and more likely to understand messages from social media and health professionals, including information about cervical cancer risk and the benefits of early screening and treatment [<xref ref-type="bibr" rid="ref56">56</xref>].</p><p>SHAP findings showed that women who have a single sexual partner have decreased cervical cancer screening rates. This finding was supported by studies conducted in Korea, Jordan, Ethiopia, and Uganda [<xref ref-type="bibr" rid="ref57">57</xref>-<xref ref-type="bibr" rid="ref60">60</xref>].</p><p>Women with a single partner have high confidence that they are free from cervical cancer risk factors because, during health facility visits and through social media information, they understand that women with single sexual partners are at a lower risk of contracting HPV and other STIs, which are the main causes of cervical cancer [<xref ref-type="bibr" rid="ref61">61</xref>].</p><p>This finding also showed that women with primary and higher education levels have increased cervical cancer screening status, which is in line with previous studies conducted in Romania, the Southwest United States, Mayuge, Ghana, and Korea [<xref ref-type="bibr" rid="ref62">62</xref>-<xref ref-type="bibr" rid="ref66">66</xref>].</p><p>A possible explanation for this could be that educated women have greater health literacy, allowing them to easily understand basic health information and services, including information about cervical cancer. Educated women also tend to have better access to resources such as health care providers, smartphones, and official websites like those of the WHO.</p><p>In addition, they may be less influenced by cultural misconceptions or stigma surrounding cervical cancer screening [<xref ref-type="bibr" rid="ref67">67</xref>].</p><p>SHAP findings also showed that women residing in urban areas had increased cervical cancer screening rates. This is in line with previous studies conducted in Nepal, Nigeria, China, and Ghana [<xref ref-type="bibr" rid="ref55">55</xref>,<xref ref-type="bibr" rid="ref68">68</xref>-<xref ref-type="bibr" rid="ref70">70</xref>]. Women residing in urban areas have improved access to health information and services through social media, public health campaigns, and proximity to health care facilities and professionals. Consequently, they tend to have a better understanding of cervical cancer compared to their rural counterparts [<xref ref-type="bibr" rid="ref71">71</xref>].</p></sec><sec id="s4-2"><title>Strengths and Limitations</title><p>One of the study&#x2019;s strengths is that it makes use of a large and varied dataset, which improves the findings&#x2019; applicability to a larger geographic area. Furthermore, complex patterns and relationships that traditional statistics can miss might be found through the use of machine learning models, and the limitations of this include issues that can impact prediction accuracy, such as self-reported information, recall bias, and missing data. Furthermore, it is challenging to determine causal links due to the cross-sectional nature of data, and the findings based on machine learning outputs should be interpreted as associations rather than causations.</p></sec><sec id="s4-3"><title>Conclusions</title><p>Wealth status, awareness of STIs, HIV testing exposure, age at first sexual intercourse, educational level, residency, smartphone ownership, having a single sexual partner, and previous health status are predictors of cervical cancer screening.</p><p>Improving education and awareness, expanding access to screening, especially in rural areas, leveraging both digital health and community-based outreach, integrating screening with other health services, and addressing socioeconomic barriers are recommended strategies to increase cervical cancer screening rates in sub-Saharan Africa.</p></sec></sec></body><back><ack><p>The authors would like to express their gratitude for the valuable time and expertise provided by everyone involved in this study.
