Welcome to CancerSurvivorMD®!

I’m Josie van Londen, MD, MS—a physician, cancer survivor, and patient living with a primary mitochondrial disease (specifically POLG). After nearly three decades caring for patients as a medical oncologist and geriatrician, my own health journey transformed the way I think about medicine, resilience, and what it truly means to live with chronic illness.

Today I write about the intersection of science and lived experience: cancer survivorship, rare disease, disability, healthcare, advocacy, caregiving, and the stories that connect us all. My goal is to make complex medical topics understandable while sharing the very human experiences behind them.

Whether you’re a patient, caregiver, healthcare professional, or simply curious, I hope you’ll find information, encouragement, and thoughtful conversation here.
