Photodynamic therapy, PDT, integrative cancer therapy, photosensitizers, light-activated cancer treatment, cancer immunotherapy, near-infrared light, integrative oncology. In this presentation episode of the Light Medicine Podcast, Dr. Michael Weber, founder of Weber Medical and a pioneer of modern photodynamic therapy, walks through the science and clinical practice of photodynamic cancer therapy.

Dr. Michael Weber is Robert Weber's father, the inventor of the multi-channel IV laser system, and one of the founding figures in modern photodynamic and photobiomodulation therapy. He is the medical director of an integrative cancer and regenerative therapy clinic in Germany.

In this lecture-style episode, he presents the fundamentals: how photosensitizers and specific light wavelengths generate reactive oxygen inside cancer cells, why that process engages the immune system, how the newest photosensitizers and delivery systems work, and how photodynamic therapy is combined with immunotherapy and other integrative approaches. He also walks through individual clinical cases from his practice.

This is a slide-based presentation, so YouTube is the best place to watch it.

In this episode, you will find:

✅ What photodynamic therapy is and how it works
✅ Photosensitizers, older and newer, and how light activates them
✅ Reactive oxygen and immunogenic cell death
✅ Why photodynamic therapy engages the immune system
✅ Reaching deeper tumors with interstitial fiber optics
✅ Liposomes and exosomes as delivery systems
✅ Combining photodynamic therapy with immunotherapy and checkpoint inhibitors
✅ Individual clinical cases from Dr. Weber's practice

Whether you are a clinician, a researcher, or exploring integrative oncology, this is a detailed lecture from one of the field's founders.
