Health social movements address several issues: (a) access to, or provision of, health care services; (b) disease, illness experience, disability and contested illness; and/or (c) health inequality and inequity based on race, ethnicity, gender, class and/or sexuality. These movements have challenged a variety of authority structures in society, resulting in massive changes in the health care system. While many other social movements challenge medical authority, a rapidly growing type of health social movement, "embodied health movements" (EHMs), challenge both medical and scientific authority. Embodied health movements do this in three ways: (1) they make the body central to social movements, especially with regard to the embodied experience of people with the disease; (2) they typically include challenges to existing medical/scientific knowledge and practice; and (3) they often involve activists collaborating with scientists and health professionals in pursuing treatment, prevention, research, and expanded funding. We present a conceptual framework for understanding embodied health movements as simultaneously challenging authority structures and allying with them, and offer the environmental breast cancer movement as an exemplar case.
