For decades, exercise was considered an optional part of cancer care—something beneficial for general health but not essential. The evidence is now overwhelming: exercise is not just supportive—it's a therapeutic intervention that recalibrates tumor biology, enhances treatment tolerance, and improves survival outcomes.
With over 600 peer-reviewed studies, Dr. Kerry Courneya's work has fundamentally reshaped our understanding of how structured exercise—whether aerobic, resistance training, or high-intensity intervals—can mitigate treatment side effects, enhance immune function, and directly influence cancer progression.
