Colorectal Cancer Screening: Why It Matters More Than You Think

It’s easy to put off a screening if you feel perfectly fine without it. After all, if nothing hurts and you feel healthy, what’s the rush?

But when it comes to colorectal cancer, waiting for symptoms can mean waiting too long.

March is Colorectal Cancer Awareness Month, the perfect time to talk about one of the most preventable cancers when caught early. At Archbold, we’re committed to helping families across South Georgia understand the life-saving power of routine screening.

And according to Esther Tan, MD, hematologist/medical oncologist at the Archbold Cancer Center, early detection truly makes all the difference.

“Colorectal cancer is one of the most preventable cancers because we have effective screening tools,” says Dr. Tan. “When we detect polyps early and remove them, we can actually stop cancer before it starts.”

What Is Colorectal Cancer? Why Is It So Common?

Colorectal cancer begins in the colon or rectum, which are parts of the large intestine. Most colorectal cancers start as small growths called polyps. Over time, some polyps can develop into cancer.

Colorectal cancer is one of the most commonly diagnosed cancers in both men and women in the United States. However, it’s also one of the most treatable when found early.

“Many patients are surprised to learn that colorectal cancer often develops silently,” explainsDr. Tan. “You may not notice any symptoms in the early stages, which is why routine screening is so important.”

When Should You Start Screening for Colorectal Cancer?

For most people at average risk, screening should begin at age 45. However, you may need to start earlier if you have:

• A family history of colorectal cancer
• A personal history of inflammatory bowel disease
• Certain genetic conditions
• A history of polyps

“We’re seeing more cases diagnosed in younger adults,” says Dr. Tan. “That’s why updated guidelines now recommend screening starting at the age of 45, even if you feel completely healthy.”

If you’re unsure when to begin, your primary care provider can help determine the right timeline for you.

Types of Colorectal Cancer Screening Tests

There are several effective screening options available:

Colonoscopy

A colonoscopy allows your doctor to examine the entire colon and remove polyps during the same procedure. It is typically recommended every 10 years for average-risk individuals.

Stool-Based Tests

These at-home tests check for hidden blood or abnormal DNA in your stool. Depending on the type, they may be done every year or every few years. Your doctor can provide guidance on obtaining an at-home stool-based test kit.

“Colonoscopy remains the gold standard because it allows us to both detect and remove precancerous polyps at the same time,” says Dr. Tan. “But the most important screening test is the one that gets done. If you’re hesitant about a colonoscopy, talk to your provider about alternative options.”

Signs and Symptoms You Shouldn’t Ignore

Even though early colorectal cancer may not cause symptoms, you should contact your healthcare provider if you experience any of the following:

• Persistent changes in bowel habits
• Blood in the stool
• Ongoing abdominal discomfort
• Unexplained weight loss
• Fatigue

“Any new or unusual symptom that doesn’t resolve should be evaluated,” says Dr. Tan. “Don’t dismiss symptoms out of embarrassment or fear. Early evaluation can save your life.”

Why Early Detection Saves Lives

When colorectal cancer is detected in its earliest stages, the five-year survival rate is significantly higher than when it is found after spreading.

Colorectal cancer screening doesn’t just detect cancer — it can prevent it.

“When we find colorectal cancer early, treatment is often less aggressive, and outcomes are much better,” says Dr. Tan. “Screening gives patients options and hope.”

At Archbold, our oncology team works closely with surgeons, gastroenterologists, and primary care providers to ensure patients receive coordinated, compassionate care every step of the way.
