In recent decades, digital and photographic life narratives by women living with breast cancer and mastectomy have gained public visibility. This article examines how a documentary and fashion photography project in contemporary Berlin rethinks normative concepts of femininity, embodiment, and sexuality through the performance of the breast cancer patient as Amazon warrior. Based on feminist theory, disability studies, media studies, and in particular Gilles Deleuze's concept of becoming, I coin the term "becoming-Amazon" for the process of relational subjectivity formation that the project opens up. Uta Melle's project shifts notions of post-mastectomy bodies as unfeminine, incomplete, or asexual and envisions and celebrates a multiplicity of relational femininities, embodiments, and erotic zones with difference. By combining digital cancer activism and an aesthetics and politics of visibility, difference, and intercorporeality, Melle's project intervenes in contemporary cancer discourse and unsettles what has been considered as redemptive cancer culture.
