Silent but Serious: Early Colon Cancer Detection Could Save Your Life

6/11/2025

Colorectal cancer remains one of the most preventable yet deadliest cancers in the United States—particularly among men. As part of Men’s Health Month and an ongoing commitment to community wellness and education, DeTar Healthcare System is spotlighting the importance of early and routine colorectal cancer screening.

According to the American Cancer Society, colorectal cancer is expected to cause 107,320 new cases of colon cancer and 46,950 new cases of rectal cancer in 2025. It is the third leading cause of cancer-related deaths in men, and second overall when combined with women. Most importantly, it’s also highly treatable when detected early—with survival rates exceeding 90% in early stages.

“Colorectal cancer is a silent threat. You may feel perfectly fine while something dangerous is developing,” said Dr. Mark Tullos, DeTar Medical Group general surgeon. “That’s why colonoscopy screenings are critical, especially if you have a family history. Catching it early allows us to act before it turns life-threatening.”

Updated Screening Guidelines: What You Need to Know

The American Cancer Society updated its guidelines in 2023, recommending that adults at average risk of colorectal cancer begin screening at age 45—five years earlier than previous guidance. This shift reflects the alarming rise in colorectal cancer among younger adults.

Between 2012 and 2021, colorectal cancer rates in people under 50 have increased by 2.4% per year, while death rates in those under 55 have increased by 1% annually since the mid-2000s (American Cancer Society, 2025).

Despite these numbers, too many men still avoid screening due to stigma, fear, or lack of symptoms. “I talk to patients every week who admit they’ve put off a colonoscopy out of discomfort or the ‘I’ll get to it later’ mindset,” said Jared Nielson, FNP, of DeTar Medical Group Primary Care North.

“We have to flip the script—getting screened is an act of strength, not weakness. Men owe it to themselves and their families to take this seriously.”

Who Should Get Screened Sooner?

While 45 is the benchmark for most, individuals with elevated risk factors may need to begin screening earlier. These include:

• A first-degree relative (parent, sibling, or child) diagnosed with colorectal cancer or polyps before age 60
• Inflammatory bowel disease (such as Crohn’s or ulcerative colitis)
• Genetic conditions (e.g., Lynch syndrome, familial adenomatous polyposis)
• History of radiation to the abdomen or pelvis
• Previous polyps or colorectal cancer diagnosis
• African American ancestry, which is associated with a higher incidence and mortality rate—screening may be recommended starting at age 40

“Talk to your doctor about personalizing your screening schedule based on these and other risk factors,” said Nielson. “Have the conversation and be proactive. This is your health.” Nielson also shared that most insurance plans, including Medicare, now cover colorectal cancer screening starting at age 45 at no cost when done through an in-network provider.

Why Colonoscopies Matter

A colonoscopy allows doctors to examine the entire colon and rectum for abnormal growths or polyps that could become cancer. The procedure also enables immediate removal of precancerous tissue—offering both detection and prevention in one. “Colorectal cancer often develops without symptoms, and by the time you notice signs, it may already be advanced,” said Dr. Tullos. “Colonoscopies give us the chance to intervene early, dramatically improving the odds of survival.”

Know the Warning Signs

Although early stages of colorectal cancer may be symptomless, later stages can cause:

• Changes in bowel habits (diarrhea, constipation, or incomplete evacuation)
• Blood in the stool or rectal bleeding
• Abdominal pain or cramping
• Unexplained fatigue or weight loss
• Low iron levels (anemia) with no known cause

“If you’re experiencing any of these symptoms—don’t wait. Early evaluation could save your life,” said Nielson.

How to Lower Your Risk

While you can’t change your genes or family history, certain lifestyle habits help reduce your colorectal cancer risk:

• Eat a high-fiber, plant-based diet rich in fruits, vegetables, and whole grains
• Limit red meat and processed foods
• Exercise regularly and maintain a healthy weight
• Avoid tobacco and limit alcohol
• Know your family history and communicate it with your provider

Take the First Step

“If you’re 45 or older, or if you have a family history, the time to act is now,” added Nielson. “This isn’t just about avoiding cancer. It’s about being here for your kids, your partner, your future.”

To schedule a screening, call your primary care provider to speak about your risks.
