Theoretical contributions in the field of diagnostic timeliness or delay in cancer

The aim of this project is to advance the theoretical understanding of the nature and source of diagnostic delay in cancer diagnosis, including tumour, patient and healthcare factors, and their variable influence in respect of different tumours and socio-demographic groups. 

This research is funded by a Cancer Research UK Advanced Clinician Scientist Fellowship awarded to Professor Yoryos Lyratzopoulos (2015-2020).
