As the number of US cancer survivors now reaches almost 16 million, understanding how to care for survivors after cancer treatment has demanded national attention. Increasingly, compelling benefits of lifestyle behaviors for cancer prevention and control have been demonstrated. In particular, physical activity is recommended as a central component of healthy living after cancer treatment. However, survivors struggle to achieve recommended physical activity and other behaviors for reasons that are still not well understood. Further, as greater than 60% of cancer survivors are older than 65 years, there is a unique opportunity to increase engagement of older adults in health programs and clinical trials. This article considers evidence from two reviews: a review on epidemiology studies of lifestyle and cancer and a review on different behavioral intervention strategies to achieve positive behavioral changes in cancer survivors. Both reviews offer important evidence on the role of lifestyle in life after cancer treatment. However, more investigation is needed on the practice of lifestyle medicine for cancer survivors, including ways to extend the reach of health promotion beyond cancer clinics, to primary care and community settings.
