What specific problem are you solving?
Cervical cancer starts in the cervix cells at the lower end of the uterus. This cancer is a pressing public health issue that disproportionately affects women in low-income African communities. In 2018, all but one of the top 20 countries worldwide with the highest burden of cervical cancer were in Africa. The empirical reality underscores that, although this type of cancer is among the most preventable, limited access to prevention, screening, and treatment services results in 90% of deaths.
One of the most significant challenges in addressing this issue is the limited access to essential preventive healthcare services, including human papillomavirus (HPV) vaccinations and preventive screenings. In many African countries, healthcare infrastructure is either underdeveloped or inaccessible to impoverished people. This lack of access leads to late diagnoses, where treatment options are limited and less effective. The shortage of pathologists in Africa exacerbates a dire healthcare situation, particularly in cancer diagnosis and treatment. For instance, a report on radiation services in Nigeria—a country with a population of 160 million and an estimated 100,000 new cancer cases annually—revealed a staggering lack of specialized medical professionals. The entire nation had only 18 radiation oncologists, 8 medical physicists, and 18 radiation therapists to meet its radiation therapy needs . This scarcity often leads to misdiagnosis, as generalists who lack specialized training in pathology are left to handle complex cases. The result is delayed or incorrect treatment and a missed opportunity for early intervention.
Early prevention, including HPV vaccination and early diagnosis, is crucial for cervical cancer. However, African countries are currently not meeting the World Health Organization (WHO)'s 2030 targets for prevention and treatment, including a 90% HPV vaccination rate by age 15, a 70% screening rate between ages 35 and 45, and a 90% treatment rate. The 5-year survival rate for cervical cancer in Africa is below 50% , which is in stark contrast to the survival rate of over 65% in developed countries. Innovative solutions are urgently needed to address unique challenges in low-income African communities. A multidimensional approach prioritizing early-phase screening for African women can significantly reduce mortality rates, aligning with WHO's ambitious goals.
What is your solution?
We designed a mobile application, “CerviScanner”, to screen for cervical cancer among African women aged 21 to 69. The app works as an intelligent screening assistant for healthcare professionals (HPs). A HP places the smartphone camera lens over the eyepiece of a microscope, which is focused on a Pap smear slide. The app captures the image and uses a sophisticated Artificial Intelligence (AI) algorithm to analyze the cellular structures for abnormalities indicative of cervical cancer. The results are then displayed on the app's interface, providing immediate, actionable insights for the HP. The mobile app is a screening tool that eliminates the need for additional hardware or computer systems. We trained our app on thousands of cervical smear test images after a thorough four-phase research methodology. The latter included dataset collection, pre-processing, predictive model selection, and code implementation. Our algorithms have reached an accuracy rate of 89% in uncontrolled settings.

Who does your solution serve, and in what ways will the solution impact their lives?
Our initial target is 5 million women aged 21 to 69 in Tunisia. The next phase will expand the application to Kenya, targeting 16.8 million women at risk of developing cervical cancer , followed by an outreach to 4.35 million women in Rwanda. Ultimately, our objective is to focus on women in the remaining top ten Sub-Saharan African countries with the highest rates of cervical cancer, including Eswatini, Malawi, Zambia, Tanzania, Zimbabwe, Lesotho, Uganda, Comoros, Mozambique, and Guinea.
A poignant example of the pressing need for our solution comes from South Africa, where women are typically asked to return to their primary healthcare clinic within 6 to 8 weeks just to receive Pap smear results. Those identified with abnormalities face an additional wait of 1 to 8 months for a colposcopy appointment. It is in this gap of time where the danger lies and where our solution intervenes. By implementing CerviScanner, the time from test to results can be reduced to 1-2 hours, allowing HPs to make immediate and informed decisions about the next steps in patient care. Our approach not only shortens the diagnosis timeline but also increases the volume of screenings, providing a significant boost in early detection rates and the potential to save lives.
As we look to bring preventive measures that are both cost-effective and sustainable, we anticipate a broad-scale impact that aligns with global health advancement goals. Our comprehensive approach is designed to be a game-changer in the regions we aim to serve. Over the next three years alone, we estimate reaching 2 million women across Africa, substantially improving access to care and contributing to the global fight against cervical cancer.

Describe the core technology that powers your solution.
Our model has been trained using 2 robust publicly available datasets that include 1,415 images, categorized under The Bethesda System. These images, sourced from real-world clinical settings, ensure our model is both relevant and effectively tuned for precision in medical diagnostics.
The AI model operates through a series of sophisticated steps beginning with image preprocessing, where images are resized, cropped, and formatted to optimize analysis. Feature extraction follows, with the AI identifying crucial image characteristics such as edges, colors, and textures. These features are essential for the model to recognize various stages of cervical lesions. During the training phase, the model adjusts its parameters to reduce errors and improve its ability to predict pre-cancerous and cancerous conditions accurately.
Once trained, the model applies its refined algorithms to new images, making predictions based on learned patterns. Post-processing of predictions enhances accuracy and reliability by filtering out uncertain results and refining the diagnosis. Beyond simple image classification, the model also supports object detection, image segmentation, and even image restoration—capabilities that broaden its applicability and effectiveness in medical imaging tasks.
Supporting the AI model is a robust backend infrastructure designed around a microservices architecture orchestrated by Kubernetes, which ensures scalability and reliability. This setup manages various functions from handling user requests to processing complex data efficiently. Our system employs cloud services including Kubernetes for automated deployment and scaling, PostgreSQL for reliable data storage and management, and GPU-accelerated virtual machines that provide the necessary computational power for intensive data processing and model training.
To further enhance the algorithm, we have incorporated pilot data collected from 189 samples across two hospitals in Tunisia, enabling us to refine the model with direct input from local real-world scenarios. This practical validation helps ensure that our application is not only theoretically sound but also effective in everyday clinical use.
