This paper explores ethical issues raised by whole slide image-based computational pathology. After briefly giving examples drawn from some recent literature of advances in this field, we consider some ethical problems it might be thought to pose. These arise from the tension between artificial intelligence research—with its hunger for more and more data—and the default preference in data ethics and data protection law for the minimisation of personal data collection and processing; the fact that computational pathology lends itself to kinds (...) of data fusion that go against data ethics norms and some norms of biobanking; the fact that AI methods are esoteric and produce results that are sometimes unexplainable and the fact that computational pathology is particularly dependent on scanning technology manufacturers with interests of their own in profit-making from data collection. We shall suggest that most of these issues are resolvable. (shrink)
