Dr. Lykke Sylow, an Associate Professor at The University of Copenhagen and a rising star in exercise metabolism, shares fascinating insights on how exercise influences cancer outcomes. She reveals that inactivity is a major risk factor for cancer, potentially more than obesity. Exercise not only reduces cancer risk but also enhances treatment efficacy, combats muscle loss during chemotherapy, and improves insulin sensitivity. The conversation emphasizes the pressing need for more research on how fitness impacts cancer recovery and prognosis.
