This week, I was pleased to attend the grand opening of Castle Biosciences’ (@CastleBio) brand-new 55,000 sq. Ft testing laboratory in Scottsdale!
Arizona is at its best when we welcome people willing to take risks, build something, create jobs, and serve others.
Castle’s work represents that commitment.
We are proud to have them in our community and #LD4.

This is why patient education matters.
Robin first learned about #TissueCypher through the Gastro Girl Podcast. She took what she learned back to her healthcare team — and later joined us to share her own Barrett’s esophagus journey.
She told me: “I no longer feel like a ticking timebomb.”
We talk a lot about views, downloads and reach. But sometimes we get to see the person behind the numbers.
That’s the impact that matters most. ❤️

One thing we've learned after years of talking with patients:
Many people normalize chronic heartburn and acid reflux because they've lived with it for so long.
But persistent reflux symptoms shouldn't be ignored.
Over time, chronic GERD can increase the risk of Barrett's esophagus, a condition that may increase the risk of esophageal cancer.
That's why we created the Barrett's Esophagus Health Hub—to provide trusted, expert-backed information on risk factors, screening, diagnosis, and treatment options.

What happens when years of acid reflux start changing the cells lining the esophagus?
In this clip, Dr. Raman Muthusamy shares a simple analogy that helps explain how Barrett's Esophagus can develop—and why chronic heartburn shouldn't be ignored.

She made a promise to her sister.
It led to her own diagnosis.
Barrett’s esophagus can develop silently in people with chronic reflux.
This story is powerful.

A lot of people live with heartburn for years…
adjusting, managing, assuming it’s normal.
Sometimes, it’s not.
This is worth understanding 👇

Endoscopy On Air Americas brings you a message from @TissueCypher - Barrett's Esophagus:
Listen as Dr. Raman Muthusamy discusses the Barrett's Conundrum: Clinicians today have effective tools to treat #BarrettsEsophagus, but face a critical challenge of identifying which patients truly need intervention. #TissueCypher is "part of this umbrella of precision medicine," helping clinicians detect high-risk patients earlier and reduce progression to high-grade dysplasia or #EsophagealCancer.

Reflux doesn’t always feel like heartburn.
It can show up as throat symptoms, chronic cough, chest discomfort, or other signs patients often overlook. GERD is also a known risk factor for Barrett’s esophagus — making recognition and monitoring important.
Foregut surgeon Dr. Dan Lister explains what patients need to know.
