Can preparing the body before cancer treatment improve recovery, reduce complications, and even protect brain function?

In this episode, Sahir sits down with Dr. Christopher Gaffney, Senior Lecturer in Integrative Physiology at Lancaster University, to explore the growing science of prehabilitation. Prehabilitation uses exercise, nutrition, and psychological support to help cancer patients better tolerate surgery, chemotherapy, and radiotherapy.

They discuss how a patient’s baseline fitness can influence treatment outcomes, why exercise is increasingly being viewed as medicine, the emerging evidence around “chemo brain,” and why healthcare may need to shift from reactive treatment to proactive preparation.

A fascinating conversation at the intersection of cancer research, physiology, and preventative medicine.

Topics Covered

•  What prehabilitation is and why it matters 
•  Exercise as medicine in cancer care 
•  How fitness affects surgery and chemotherapy outcomes 
•  The science behind chemo brain and fatigue 
•  Why medicine needs to think earlier, not later
