Cancer survivors have strong personal desires to resume work to feel productive and meet financial needs. However, they may be faced with physical and psychological challenges. This research aims to: examine cancer survivors' perspectives on supports needed when returning to work; investigate sex and gender differences when returning to work; and explore demographic and employment factors that may influence this process. An exploratory qualitative design was used. The study had two phases: focus groups and one-on-one semi-structured interviews. Inductive thematic analysis was used to analyze the data. The total sample includes 15 participants, 87% female and 13% male. Key themes include: changing perspectives on self and work; managing work and social systems; determining disclosure and accommodation; and the importance of supports for return to work and daily life. This study informs cancer rehabilitation research by developing an understanding of the supports needed to help cancer survivors return to work successfully. Chapter 1: Introduction Purpose of Study In 2017, the Canadian Cancer Society released a report stating that about 1 in 2 Canadians are expected to be diagnosed with cancer in their lifetime (Canadian Cancer Society, 2017). Furthermore, it predicts that nearly 55% of all new cases of cancer will occur in people aged 20-69 years (Canadian Cancer Society, 2017). Given that working age is normally defined as 15 to 64 (Organisation for Economic Cooperation and Development [OECD], 2017), most Canadians who are diagnosed with cancer are likely to be interested in returning to or staying at work as a way to establish normality, social relationships, and enhance quality of life (Peteet, 2000; Steiner, Cavender, Main, & Bradley, 2004). In fact, a literature review by Spelten, Sprangers, and Verbeek (2002) found that, on average, 62% of cancer survivors are able to stay at work or return to work after treatment. Another cohort study found that this number increases to 85% after 4 years, confirming that many cancer survivors are able to remain or stay at work after treatment (Short, Vasey, & Tunceli, 2005). Cancer impacts not only individuals, but also stakeholders throughout the healthcare system and in the workplace (Maunsell,
