147: Palpating Fibrosis, Easing Inflammation (with Geoffrey Bove and Holly McMillan)

🎙What can trained hands feel in irradiated tissue—and how might that inform both research and practice?

In this episode, Til Luchau and guest cohost Cathy Ryan, RMT, talk with neurobiologist Dr. Geoffrey Bove and manual therapist/speech pathologist Holly McMillan about their collaborative animal study. They explore how massage therapy may influence radiation-induced fibrosis, the use of palpation as a formal outcome, and the challenges of correlating what we feel with what science can measure. This wide-ranging discussion offers practical takeaways for manual therapists working with inflammation, scarring, or post-radiation clients.

Stick around after the outro for a candid “off-mic” bonus segment where Holly describes her hands-on work in surgical oncology settings.
