AI-Driven Large-scale Screening for Oral and Oropharyngeal Cancer

Funded by TDB Department of BioTechnology, Government of India
and VINNOVA Swedish Agency for Innovation Systems.


High mortality of oral and oropharyngeal cancer can be attributed to late diagnosis. Brush sampling and cytological analysis is efficient for early detection of cancer, but the analysis is costly and requires highly skilled expertise. Modern AI-techniques have made it feasible to radically reduce the analysis cost while at the same time increase speed and diagnostic accuracy. We have developed a deep learning based pipeline for efficient oral cancer screening and a low cost sample processing technique which meet the performance needs of large scale screening in resource-limited environments. The AIDOScan project aims to scale up our solutions towards large-scale implementation and usage in everyday healthcare in Sweden and India. The project will additionally explore if virus infections, such as HPV or COVID-19 can be detected using similar AI-cytology analysis.

Five year multi-center study started, including 1,000 patients:
