This paper examines cancer through the lens of abjection. While cancer can be understood as an abject lifeform, we explore what we name the abject ontologies created through both cancer detection technologies/practices and cancer treatment, specifically the drug combination Adriamycin and Cytoxan. We ask: what are the abject ontologies produced through living with and living on from cancer diagnosis and treatment? Our concern is to map how cancer undoes our supposedly stable categories inherited from modernist logic, challenges our very ideas (...) of what it means to be human, and demands an ethical reorientation of public cancer discourse.
