Abstract
Simple SummaryGlobally, cancer is a major issue and an increasing number of people live with cancer. Lifestyle-associated factors play a major role in cancer prevention. Being physically active and limiting the amount of time spent sitting reduce the risk of developing several types of cancer. Furthermore, physical activity before, during, and after cancer diagnosis has been found to improve cancer outcomes. In addition, reduced levels of time spent sedentary may lead to improved outcomes in cancer survivors as well. This narrative review summarizes the existing evidence on the relationship of physical activity and sedentary behavior to cancer survival and other health outcomes in cancer survivors. The review provides an overview on the barriers, facilitators, and other factors that determine the levels of physical activity and sedentary behavior in cancer survivors as well as on the current recommendations on physical activity and sedentary behavior for cancer survivors.From a public health perspective, cancer is a major issue, and it contributes to a high economic and societal burden. Lifestyle-associated risk factors play a crucial role in cancer prevention. The present narrative review aims to summarize the existing evidence on the relationship of physical activity and sedentary behavior to cancer survival, including the evidence on mortality and other health-related outcomes. There is strong evidence that physical activity before, during, and after cancer diagnosis improves outcomes for breast and colorectal cancers. In addition, there is emerging evidence that reduced levels of sedentary behavior in cancer survivors are associated with improved outcomes. Future studies are needed to strengthen the evidence and to provide details on additional cancer sites. In the meantime, existing recommendations for physical activity and sedentary behavior in cancer survivors should be followed to improve the health status of cancer survivors.
