"It may not cure you, it may not save your life, but it will help you"

In the modern world, we are experiencing an epidemiological shift represented by the increasing prevalence of chronic diseases relative to that of acute diseases: more people are living longer, with more diseases, than ever before in human history. How are we to understand and to respond to this change? A study of provision of cancer treatment in Western Australia, especially among Indigenous populations, can illuminate ways in which healthcare providers and societies might better understand the treatment of chronic disease: healthcare providers should take care to appreciate patient perspectives and beliefs about disease aetiology and treatment. Consideration of treatment of disease in the ancient Graeco-Roman world supports the view that effective healing and maintenance of patient wellbeing occurs when healers communicate clearly with their patients about disease and treatment progression, and when healers are open-minded about patients' utilisation of multiple treatment modalities.
