Ambivalent Speculations: Learning to Live with Barrett’s Esophagus in the UK Using Facebook Support Groups

Drawing on fieldwork in Facebook support groups, in this article I explore how people, now patients, learnt to live with Barrett's esophagus, a risk state or "precancer" for a type of esophageal cancer. This diagnosis brought the possibility of both facing and averting cancerous futures into the present. Far from passive recipients, members worked to foreground speculations of "wanted futures" in which prompt surveillance successfully prevented cancer deaths, transforming cancer risk into an opportunity for hope. Speculation here was an ambivalent and active process, involving not only the "observation of potentiality," but the opening up and foreclosing of both desirable and undesirable potentialities.
