This book presents an important reflection on the concept and limits of the Fundamental Right to Health as opposed to a supposed  Right to Hope  in the context of the treatment of patients with advanced cancer. The central idea of the work is the question of whether and to what extent patients with advanced cancer have the right to legally demand a palliative treatment whose efficacy has not been proven from the point of view of the desired objectives. The book demonstrates how hope cannot be subject to legal protection and, also, that, even if theoretical-legal reasons were not sufficient for the absence of an abstract right to hope, ethical reasons would be. The work concludes that the best palliative care, rather than palliative treatment, guarantees the best right to health for advanced cancer patients, especially in terminal cases.
