KEYWORDS body image, cancer, embodiment, treatment effects, quality of life 1 | INTRODUCTION Physical appearance and the image of the human body have long been relevant in a wide variety of clinical settings in medicine. 1-3 The concept of body image is of particular importance to oncology, as all types of cancer and its treatment have some impact on it. 4-7Body image has obvious connotations of physical appearance. However, it is complex, with multiple aspects that have important but not always obvious, connections with cancers and their treatment problems arising from bodily changes. This presents a challenge in research and clinical care. Breast cancer has been the most widely investigated cancer in empirical research in psycho-oncology, [8][9][10][11] and findings show that impaired body image can have marked negative and potential long-term effects on psychological adjustment and quality of life. However, body image outcomes and treatment effects on the body are often reported separately in quality of life outcomes. We suggest this division is problematic and the challenge is to work with a coherent framework that demonstrates interrelated body image and body changes.Defining body image has proved elusive, but it can be approached in different ways. For example, established cognitive behavioural perspectives 12 have been adapted for cancer patients, 13 foregrounding psychological assessments of body image disruption. Other models, designed for use in clinical practice, acknowledge self-perceived appearance change but emphasise different aspects, such as decreased physical and social functioning. 14 Price includes the concept of an ideal body, influenced by sociocultural factors, 15 and Fingeret 16 presents a comprehensive management model, embracing treatmentrelated bodily changes and psychosocial difficulties.We argue that body image reflects alterations in appearance and bodily changes and functioning. We uphold a view that body image is used to describe all the ways people conceptualise and experience their body and to acknowledge the social as well as the physical reality of the body. 17 We refer to this as "embodied body image."Links to the physical body are not new, having been proposed by Schilder in 1950, 18 and are widely reported in psycho-oncology literature. 6,8,16,[19][20][21][22] However, these complexities have not been fully theorised. The challenge is to understand the subjective, changing nature of body image and incorporate important connections to the altered body and social context.In order to meet this challenge, we propose a coherent basis for understanding embodied body image in cancer patients. We present a distinctive framework rooted in social theory that embraces both appearance changes and the physical body in everyday life and activities. Taking a social practice perspective helps to go beyond the objective clinical setting and into patients' lived experiences of cancer (that is, their everyday experience of living with and beyond cancer, the choices they make, and the knowledg...
