RESUMEN
PURPOSE OF REVIEW: This article serves to describe recent controversies in cancer prehabilitation including efficacy, dose, cost effectiveness, stakeholder input, and international implementation. RECENT FINDINGS: Appropriate frequency, type, and timing have yet to be determined, but high intensity exercise is recommended. Costs are favorable when modeled and information on costs of real-world application are forthcoming. Patients are interested in and willing to attend cancer prehabilitation. Cancer prehabilitation research is spreading throughout the world. Cancer prehabilitation includes assessment of a newly diagnosed cancer patient's baseline fitness and targeted interventions to improve their health before surgery, chemotherapy, or radiation. Cancer prehabilitation improves fitness as measured preoperatively and improves outcomes postoperatively.
