This paper is about transnational cancer care in Asia. People with terminal diseases such as cancer increasingly escape devastating prognosis of their local regimes of clinical diagnostic truth by traveling to destinations where medicine is more advanced, yet affordable for them, and hence offers a broader scope for hope. The paper suggests that transnational cancer care provides an instructive case of the enormous geographical disparities in the availability of therapies and how this, combined with economies of hope and the marketization of health care, affects patients and their family caregivers. The primary contribution of the paper is the introduction of the concept of relational subjectivities to the health mobilities literature. The findings presented proof that the concept provides a fruitful analytical lens, yielding not only fresh empirical insights but prompting re-conceptualizations of medical travel itself as
hopeful, yet risky transnational acts of family care.
