ep 13 - Why Cancer Survivors Stay Exhausted Even When “Active.” Activity, Exercise and Cancer Rehab
What if being exhausted all day does not actually mean your body is getting stronger? In this episode of The After. Cancer Podcast, Dr. Leslie Waltke breaks down one of the most misunderstood topics in cancer survivorship and recovery: the difference between activity, exercise, and rehabilitation.
Many cancer survivors spend their days physically and emotionally exhausted, yet still feel weak, deconditioned, stiff, or unable to fully return to life after treatment. Why? Because movement is not always the same thing as exercise — and exercise is not the same thing as rehabilitation.
In this episode, Dr. Waltke explains how cancer treatment affects strength, endurance, balance, mobility, and overall function, while also helping listeners understand why intentional movement matters so much during and after cancer treatment. She discusses fatigue, deconditioning, fear of movement, rehabilitation needs, and the critical role of physical therapy and oncology rehabilitation in helping people regain confidence, independence, and participation in life.
This conversation is both deeply practical and deeply human — rooted in medicine, spoken in human.
