This paper examines how to apply a spatial approach (relational and geographical) to care pathways for their better integration within their territories. Based on the case study of a senology department of a French Cancer Diagnosis, Treatment and Research Center, we apply a mixed research methodology using qualitative data (synthesis documents, meeting minutes, in-depth interviews) and quantitative data relating to the mobility and geographical location of a cohort of 1798 patients treated in this center. Our results show the inseparable nature of the relational dimension and the geographical approach to move towards greater integration of breast cancer care pathways. This inseparability is constructed from the proposal of a method for mapping the integrated care pathways in their territories. This method, applied to our case study, allows us to identify four main categories of pathways for the cohort of patients studied.
