EsoGuard

EsoGuard EsoGuard esophageal DNA test is a highly accurate test that detects altered DNA to help diagnose esophageal precancer and cancer.

Scott wasn't at the doctor because he was worried about esophageal cancer.

He was seeing his Allergist for a routine visit when a poster for esophageal precancer caught his attention. He recognized he was at increased risk and decided to get tested.

After a positive EsoGuard® result, Scott underwent further evaluation, was diagnosed with esophageal precancer, and received treatment.

It started with something simple: recognizing his risk.

Scott's story is a powerful reminder that awareness can lead to action, and finding precancerous early can create an opportunity to treat it before it becomes cancer.

Early detection is only effective if people can actually access it.

For many patients at risk for esophageal precancer, going straight to an endoscopy may not always be the easiest—or most practical—first step. That’s where non-endoscopic testing with EsoGuard® can help.

As Dr. Richard Englehardt shares, EsoGuard helps him identify patients who may benefit from further evaluation, including those who otherwise may not have been tested.

It’s about making early detection easier to access—and helping more at-risk patients get on the right path.

Esophageal cancer claims more American lives each year than melanoma and cervical cancer combined. Yet it receives only a fraction of the public awareness.

Too often, it's diagnosed only after symptoms appear, when treatment options are more limited.

The goal isn't to detect cancer—it's to find precancer first.

Barrett's esophagus—the precancerous condition that can lead to esophageal adenocarcinoma—can be detected, monitored, and treated before cancer develops. EsoGuard® helps make that possible with a non-invasive test for at-risk patients.

Awareness is the first step. Early detection is what changes outcomes.

Esophageal cancer is one of the fastest-growing cancers among men over 55 — and for years, screening meant endoscopy: invasive, costly, and often negative.

So when a surgeon with several risk factors of his own chooses to get screened, it's worth paying attention.

Dr. Steven D Schwaitzberg, Chairman of the Department of Surgery at the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo, didn't just recommend EsoGuard. He took the test.

"EsoGuard allows physicians to screen patients conveniently in the office and reserve endoscopy for those most likely to benefit. With several risk factors myself, I chose to have the EsoGuard test and was reassured by the results."

That's the shift: a simple, non-invasive DNA test that makes early detection accessible to the patients who need it most.

No one hands you the list of cancers that come with the job when you become a firefighter.

Esophageal cancer is one of them — and firefighters face a significantly higher risk.

By the time symptoms appear, it's often already advanced. That's what makes this cancer so dangerous, and early detection so critical.

The good news? Esophageal precancer can be detected—and treated—before cancer develops.

Because the best way to fight esophageal cancer is to prevent it.

Diagnostics are the GPS of health care — and the American Clinical Laboratory Association Power of Knowing campaign is showcasing exactly why that matters.

We're honored to have an EsoGuard® patient story featured as part of this initiative. It's a powerful reminder of what early detection can mean for patients and their families.

Firefighters face a 62% higher risk of esophageal cancer. One family turned that statistic into action — and EsoGuard gave them answers.

For 21 years, Steven Dorsey has answered the call — a third-generation Baltimore City firefighter, a father of four, and a grandfather of five. Steve has spent his life putting others before himself.

Now he's fighting a battle no amount of training could prepare him for: stage 4 esophageal cancer.

Steve's only warning sign? Difficulty swallowing — a symptom most would dismiss without a second thought. By the time he was diagnosed in February 2025, the cancer had already spread to his lymph nodes and liver.

The reality is staggering. Firefighters face a 62% higher risk of developing esophageal cancer than the general population. Years of exposure to toxic chemicals, smoke, and carcinogens take a silent toll — and without routine screening, this aggressive cancer is often caught far too late.

But it doesn't have to be this way. Today, there is a test that can detect esophageal precancer before cancer develops — giving people a chance to act early.

Even in the midst of his own treatment, he's using his voice to advocate for esophageal screening across the country — determined to make sure the next firefighter gets answers sooner than he did.

Awareness isn't just about information. It's about action. Because earlier detection can change the course of this disease — and the lives it touches.

Awareness leads to action.
Action leads to earlier detection.
And earlier detection can save lives.

As Month comes to a close, our focus on early detection continues.

An estimated 22,530 Americans will be diagnosed with esophageal cancer this year. Behind every statistic is a person — a parent, a partner, a friend — and a family whose life is forever changed.

Early detection can change outcomes.

While the incidence of many major cancers is flat or declining, esophageal adenocarcinoma continues to rise.

Over the past four decades, cases have increased more than 500% in the U.S.—yet awareness and screening have not kept pace.

Today, esophageal cancer remains one of the most lethal cancers, with a five-year survival rate of just ~20%.

What makes this especially challenging: it’s often silent until it’s advanced.
What makes it especially important: it’s often preventable.

Esophageal adenocarcinoma typically develops from Barrett’s Esophagus—a precancerous condition that can be detected before cancer forms. Yet more than 90% of patients diagnosed were never identified at the precancer stage.

At least 30 million at-risk Americans with chronic heartburn (GERD) are recommended for screening under major clinical guidelines—but most go unscreened.

At Lucid Diagnostics, we’re focused on enabling a different strategy—one centered on identifying esophageal precancer earlier, before it progresses to cancer.

The EsoGuard® DNA test offers a non-endoscopic, in-office approach to detecting precancer—helping direct the right patients to further evaluation.

Because when incidence is rising,
early detection isn’t optional—it’s essential.

“I may not be sitting here now if they hadn’t caught it when they did.”

Veteran Dan Rathke didn’t think much of his severe acid reflux—and like many people, he rarely went to the doctor. He had no idea he could be at risk for esophageal cancer.

But his primary care physician, Dr. Jamie Glover, recognized the risk factors and recommended screening with the EsoGuard® test.

That decision led to the detection of precancerous changes—before they had the chance to progress to cancer.

When it comes to esophageal cancer, detecting disease at the precancerous stage is critical, and possible, with the EsoGuard test.
