This research project will develop AI methods and approaches for robust, sustainable and trustworthy breast cancer screening with mammography. We expect findings will be transferable to other medical screening programs. Breast cancer is the most common cancer and the leading cause of cancer death among women worldwide. Early detection of breast cancer through screening is recommended by international health organizations to reduce this mortality. It is considered to expand the screening program by examining more women. The use of AI can lead to a larger capacity to do screening and detect cancers, reduce overdiagnosis, and by this save lives and give new opportunities for improved health services. Furthermore, we need to understand the effects of using AI in this context. To address this, the project will involve AI experts, medical experts, organizers and practitioners within mammographic screening to create a strong interdisciplinary team. The main novelties of the proposed project are: * Develop methods that can handle domain shifts without costly annotation of new data. Current methods have problems handing images from different equipment, operators and cohorts. * Exploitation of time series in AI breast cancer screening. Radiologists exploit prior mammograms when doing their manual reading, while it is rarely used in current AI-based models. * Interpretation of predictions from AI breast cancer models such that radiologists can understand the predictions. This gives trust and makes it easier to improve the AI method and combine this with manual reading by radiologists. * Find the differences in the prediction between radiologist and AI both statistically and using data collected in the screening program as a basis when we combine the two methods. * Develop AI systems that is usable for radiologists in mammographic screening utilizing the strength of each approach. A new screening program should give better predictions and use less radiology resources.
