“I’m Not Dying From This”

How one simple test helped Nancy catch colon cancer early

At 68, Nancy Culling had a full, happy life. She retired from teaching, and enjoyed spending her days reading, swimming, and making glass art in her Florida home. She and her husband, Larry, loved spending time together and visiting their son.

Health-wise, Nancy considered herself lucky. She had no major medical issues — and when her doctor suggested she get screened for colon cancer, she always said no.

“I told her, ‘No, I'm not doing that!’” Nancy laughs. “I just didn’t want to have a colonoscopy. My mother had one years ago, and she told me how embarrassed she was. I said, ‘Nope, not doing that in front of anyone!’”

A Colon Cancer Screening Option That Changed Everything

I just didn’t want to go through something that felt embarrassing,” she says. “So I kept putting it off.”

That changed when she learned about a use-at-home screening option—the Cologuard® test—that she could complete privately and without a clinic visit. The kit arrived at her home with clear instructions, and the simplicity of the process eased her worry.

“I said, okay, I’ll do that,” Nancy recalls. “It’s in the privacy of my own home. It came with clear directions — no problem at all.”

Completing the test was a small step, but it became a turning point in Nancy’s life.

How Care Gap Programs Bring Screening to More People

Like Nancy, millions of adults across the country fall behind on colorectal cancer screening each year—often because of scheduling challenges, transportation barriers, or uneasiness about traditional procedures.i,ii To help close these gaps, some health systems and plans bring screening directly to peoples’ homes through care gap programs.

Health plans and systems identify average-risk adults who are overdue for colorectal screening. Licensed clinicians issue prescriptions, where clinically appropriate, based on a review of patient eligibility information. Cologuard kits are then mailed—along with educational materials that describe appropriate use and completion of the test— directly to the individual’s home. Participation is optional, and most insurance plans cover the full cost.iii The process allows individuals to complete colorectal screening privately, removing many of the obstacles that commonly prevent people from getting screened.

If a Cologuard test result is negative, the person is typically due for screening again in three years.iv A positive result means a follow-up colonoscopy is needed to complete the screening evaluation, which is covered with no cost-sharing for most health plans.v

Nancy’s Life-Changing Result

When Nancy’s results came back, they were positive — which prompted her doctor to schedule a follow-up colonoscopy to take a closer look.

“I wasn’t thrilled,” Nancy admits. “But I did it.”

Doctors found what Nancy describes as a “polyp gone bad” — too large to remove during that first colonoscopy. The polyp had to be surgically removed.

That surgery changed the course of her life.

“They took out about a foot of my bowel,” Nancy recalls. Afterward, her surgeon said, ‘Do you want the good news or the bad news?” Nancy said, “The bad.” He told her it was cancer, but the good news was they got it all. It hadn’t spread to any lymph nodes. She didn’t need chemo or radiation.

Nancy’s diagnosis: stage 1A colon cancer — caught so early that the cancer made up less than five percent of the cells in the growth. Nancy remembers how shocked the surgeon was. He talked to her about how Cologuard found this before it could have become a problem.

The Power of Early Detection

Colorectal cancer is the second leading cause of cancer deaths in the United States.vi But when found early, it’s highly treatable — with survival rates over 90%.vii

“I had no symptoms,” Nancy says. “I felt fine. If I hadn’t done this, I wouldn’t have known until it was too late.”

She now has regular checkups, but she never needed chemo or radiation.

Encouraging Others to Take That Step

Nancy shares her story not for sympathy, but for awareness. “I think people need to know how important screening can be,” she says. “Cologuard really works. It found my cancer early. It’s not just something you see on TV — it’s real.”

When she tells friends about her experience, she hopes her words stick with them the next time their doctor or health plan brings up screening.

“Do it,” she says simply. “Don’t wait. You don’t want to find out the hard way. If I’d done something sooner, maybe I wouldn’t have needed surgery. But I’m so grateful it was found when it was.”

Nancy’s story isn’t just about luck — it’s about action. A small decision, taken at the right time, made all the difference.

“It’s nice to know,” she says softly. “That I’m not dying from this. I’m still here. And that’s something worth sharing.”

About the Cologuard test

The Cologuard test is intended to screen adults 45 years of age and older who are at average risk for colorectal cancer by detecting certain DNA markers and blood in the stool. Do not use if you have had adenomas, have inflammatory bowel disease and certain hereditary syndromes, or a personal or family history of colorectal cancer. The Cologuard test is not a replacement for colonoscopy in high risk patients. Cologuard performance in adults ages 45-49 is estimated based on a large clinical study of patients 50 and older. Cologuard performance in repeat testing has not been evaluated.

The Cologuard test result should be interpreted with caution. A positive test result does not confirm the presence of cancer. Patients with a positive test result should be referred for colonoscopy. A negative test result does not confirm the absence of cancer. Patients with a negative test result should discuss with their doctor when they need to be tested again. False positives and false negative results can occur. In a clinical study, 13% of people without cancer received a positive result (false positive) and 8% of people with cancer received a negative result (false negative). Rx only.

This story reflects on an individual’s experience. Not every person will have the same treatment, experience, outcome, or result.

The Cologuard test is prescribed by your health care provider. Talk to your health care provider about available screening options and whether the Cologuard test may be right for you. There are potential risks associated with the Cologuard test and it may not be appropriate for all patients. For more information about the risks, talk to your health care provider or visit www.Cologuard.com for more information.
