This premier gathering unites radiation oncologists, researchers, and industry leaders from around the globe. Tailored for radiation oncologists, medical physicists, radiation therapists, and oncology professionals, ASTRO 2025 presents an extensive program aimed at reimagining radiation medicine, investigating emerging clinical applications, and advancing research and patient care in radiation therapy. Attendees can look forward to state-of-the-art scientific sessions, engaging educational presentations, and exhibits highlighting the latest innovations in radiation oncology.
Our team at OncoDaily has selected a few posts from ASTRO25 Day 2 that you should not miss!
“Welcome to Day 2 of ASTRO25!

“Recipient of a prestigious ASTRO Clinical Resident Poster Award, Victor Lee presented new findings linking certain genomic alterations to brain metastases in NSCLC.
“Grateful to our amazing mentors who led the Speed Mentoring session for international members at ASTRO2025 .
Inspiring to exchange ideas and build connections that shape the future of global Radiation Oncology.”
“The first day of ASTRO 2025 was a whirlwind of conversations, reunions, and new connections.
Being here with the Oncosoft team reminds us that behind every technology, there are real people—doctors making tough decisions, patients fighting with courage, and colleagues pushing each other to do better.
Today we listened, we learned, and we shared. And honestly, the most meaningful part was meeting so many of you face-to-face.
These moments fuel us more than any presentation ever could.
Here’s to the rest of ASTRO 2025—we can’t wait to keep the conversations going.”
“ASTRO 2025
As I sit here in Jackson, MS preparing to head to ASTRO, I can’t help but reflect on the journey that brought me here.
From setting up my very first booth with Deborah Churchill and Andrea VanderWeide (yes, that crimson carpet) … to the fresh suits and big ideas alongside Daniel Booker … this path has been more than a career. It’s been a journey—much like the one patients describe in cancer care.
I’ve traveled from therapist, to administrator, to consultant. Along the way, I’ve learned that this is a long game. It takes patience, persistence, and resilience. There will always be distractions—shiny objects, quick wins, shortcuts—but the truth is, intentions and agendas always show themselves over time.
Sometimes you lead. Sometimes you follow. Sometimes you push, and sometimes you pull. And often, there are no spectators on the road—only fellow travelers. What you do for others, and the gratitude you show for what they do for you, is what carries all of us further down the path.
The real difference comes from integrity over time—being bold, consistent, and staying true to your convictions. Purpose and focus matter because the road is long. There are bumps, smooth stretches, uphill climbs, and downhill glides. But it is still one road, and it demands resilience.
This ASTRO is about that commitment: evolving as we go, but never losing sight of the purpose and passion that drive us.
For those who have been part of this journey—thank you. The road is long, but it is better traveled together.”

“BREAKING NEWS:
Leo Cancer Care is using ASTRO 2025 to launch Grace, the company’s upright photon therapy system. Grace is named after American computer scientist and U.S. Navy Rear Admiral Grace Hopper, who famously said, ‘The most dangerous phrase in language is ‘But we’ve always done it this way.’ The name reflects Leo Cancer Care’s mission to challenge the conventions of radiation therapy.
Please note: Leo Cancer Care’s Grace solution is under development and is not cleared or approved for sale.
It is presented for research and discussion purposes only.”
