Colorectal Cancer Screening: Options, What to Expect, and When to Start

Doctor and man talking about colonoscopy options.

As we head into Colorectal Cancer Awareness Month, it’s time to talk about the one cancer "success story" we can all get behind: prevention.

Colorectal cancer remains a major health challenge. For 2026, the American Cancer Society (ACS) estimates roughly 158,000 new cases and 55,000 deaths in the U.S. alone. While rates are dropping in older adults, diagnoses in people under 50 are on the rise — making it the leading cause of cancer death in men under 50 and second for women.

The silver lining? This is one of the few cancers that can be stopped before it even starts. By finding and removing precancerous polyps, screening doesn't just find cancer — it can prevent it.

When Should You Start?

Guidelines have shifted recently due to a rising trend among younger adults. Here is the current roadmap for those at average risk:

  • Ages 45–75: This is the "screening window." If you are in this age bracket, regular screening is a must.
  • Ages 76–85: Screening is an individual decision. Talk to your doctor about your health history and prior results.
  • Ages 85+: Screening is generally no longer recommended.

Are You "Average Risk"?

Most people are, but you might need to start earlier than 45 if you have:

  • A family history of colorectal cancer or certain polyps.
  • A personal history of inflammatory bowel disease (Ulcerative Colitis or Crohn’s).
  • A known hereditary syndrome (like Lynch syndrome or FAP).
  • A history of radiation to the abdomen or pelvis.

Pro Tip: If a close relative was diagnosed, find out how old they were. Doctors often recommend starting screening 10 years earlier than the age at which your relative was diagnosed.

Your 2026 Screening Menu: Which Test is Best?

There is no "single best test" for everyone. The best test is the one you actually complete. Most options fall into these categories:

Screening Options at a Glance

Stool-Based (FIT) Every Year At home; No prep; Non-invasive. Must be done every single year.
Stool DNA (FIT-DNA) Every 3 Years Highly convenient; No prep. Higher rate of "false positives" than colonoscopy.
Colonoscopy Every 10 Years Can find AND remove polyps in one visit. Requires bowel prep and a day off for sedation.
CT Colonography Every 5 Years Non-invasive "virtual" scan. Still requires bowel prep; can't remove polyps.

The "Golden Rule" of Stool Tests

If you choose an at-home stool test (like FIT or Cologuard) and it comes back abnormal/positive, you must follow up with a colonoscopy. Without that second step, the screening isn't complete. In 2026, many insurance plans now cover this follow-up colonoscopy as part of the screening process, but always double-check your coverage.

Listen to Your Body: Symptoms to Watch For

Screening is for people who feel fine. If you are experiencing any of the following, don't wait for your next scheduled screening — call your doctor now:

  • Changes in bowel habits (diarrhea, constipation, or narrowing of the stool) lasting more than a few days.
  • Rectal bleeding or blood in the stool (which may look dark or tarry).
  • Abdominal cramping or persistent gas pain.
  • Unexplained weight loss.
  • Weakness or excessive fatigue (often a sign of anemia).

Your March Action Plan

  1. Check the Calendar: If you’re 45 or older and haven’t been screened, this is your sign.
  2. Gather the History: Ask your parents or siblings about their history with polyps or cancer.
  3. Choose Your Path: Ask your doctor: "Based on my history, am I a candidate for an at-home test, or should we go straight to a colonoscopy?"
  4. Follow Through: If you choose a yearly test, set a recurring calendar alert.

Bottom Line: Colorectal cancer is highly treatable and often preventable. When caught at a localized stage, the 5-year survival rate is 91%. Give yourself the gift of a clean bill of health this March.

Cancer Prevention & Early Detection: A Roadmap for Every Age

Cancer is a heavy word, but prevention is where you take your power back. The goal isn’t perfection; it’s about understanding your risks and staying ahead of the clock. Most screenings come back normal. When they don’t, catching things early—at the "precancerous" or early stage—is a total game-changer for treatment.

What’s Actually Driving Your Risk?

It’s helpful to separate the "fixed" from the "flexible" so you know where to focus your energy.

Factors You Can't Change

Age: Risk naturally increases over time.

Genetics: Your family's health history.

Past History: Prior radiation or conditions.

Biology: Hormones and reproductive history.

Factors You Can Influence

Tobacco & Alcohol: The two biggest movers.

Metabolic Health: Diet and physical activity.

UV Exposure: Sun protection and tanning.

Infections: Staying current on HPV and Hep B/C.

Prevention Basics: The "Big Wins"

You don’t have to overhaul your entire life today. These four habits offer the highest "return on investment" for your health:

  • Tobacco: Support > Willpower. Quitting is hard, but you don't have to white-knuckle it. Using coaching and nicotine replacement (patches/gum) doubles your chances of success.

  • Alcohol: The "Less is Better" Approach. You don't necessarily have to totally abstain from drinking, but cutting back — even by two drinks a week — lowers risk for several cancers (including breast and colon).

  • Movement & Fiber: Focus on "crowding out" the bad stuff. Adding fiber (beans, berries, grains) and walking 20 minutes a day creates a metabolic environment where cancer has a harder time starting.

  • Test Your Home for Radon: In Connecticut, radon is a significant but invisible risk. It’s the leading cause of lung cancer in non-smokers.

Screening Timeline: What to Do & When

Note: This is for average-risk individuals. If you have a family history, your "start date" might be 10 years earlier than what is listed below.

Teens & 20s: The Foundation

  • HPV Vaccination: Ideally completed by age 11–12, but "catch-up" shots are effective through age 26 (and sometimes up to 45).

  • Cervical Cancer: Screening (Pap tests) begins at age 21.

  • Know Your Roots: Ask your relatives about their health history now. It’s easier to get these details before records get lost.

Ages 30–39: The Maintenance Phase

  • Cervical Screening: Continue Pap/HPV testing as recommended by your doctor.

  • Risk Check-in: A great time to discuss family history changes or lifestyle goals with your primary care provider.

Ages 40–49: The Shift to Proactive

  • Breast Cancer: Routine mammograms now officially begin at age 40 for most women.

  • Colorectal Cancer: Screening starts at age 45. You can choose between a colonoscopy or an at-home stool test (like Cologuard).

Age 50–70+: Staying Vigilant

  • Lung Cancer: If you have a 20-pack-year smoking history, ask about a yearly low-dose CT scan.

  • Prostate Cancer: Starting at age 55 (or earlier for Black men), have a "shared decision-making" talk with your doctor about PSA testing.

  • Hepatitis C: A one-time blood test is recommended for all adults to prevent liver cancer.

The "Red Flag" Rule: Regardless of your age or when your last screening was, see a doctor for:

  • Unexplained weight loss

  • Lumps or skin changes

  • Changes in bowel habits or unusual bleeding

  • A cough that won't quit

Uncas Health District in Your Community: Cancer Detection and Prevention

During National Public Health Week, we’re highlighting some of the important work Uncas Health District does in our community. One of our key services is providing free, potentially life-saving screenings for individuals who might have trouble accessing these crucial medical services.

Cancer is a serious health concern, and one of the leading causes of death in the United States. Early detection is key in the fight against this serious illness, and we’re proud to partner with the state to make these screenings available.

 

The Power of Early Detection

Cancer can develop slowly, which is why regular medical check-ups are important for identifying their symptoms. Primary care physicians routinely order screenings for their patients in order to identify potential signs of cancer and track changes in the body over time.

If cancer is detected too late, there is a greater chance that it will have metastasized, or spread to other parts of the body. When this occurs, there is a much greater risk of serious illness or death.

Early screening allows cancer to be treated before it can progress. This not only means that the survival rate is improved, but also that it can be addressed with less invasive methods that improve one’s quality of life during treatment and recovery.

Unfortunately, people may not think that these screenings are accessible to them. This is most likely to occur when someone is uninsured or underinsured, or when they have a lower income and do not believe they can afford medical services.

 

Making Screenings More Accessible

Uncas Health District is a proud participant in the Connecticut Breast and Cervical Cancer Early Detection Program. This program offers free screening, diagnostic, and treatment referral services to medically underserved women. 

By setting up an appointment with the Uncas Health District, qualifying women can receive clinical breast exams, Pap smears, and mammograms at no cost. The services are available to qualifying women, including those living at or below 250% of poverty level or those who lack the necessary insurance to cover these screenings. Learn more about eligibility criteria here, and contact the Uncas Health District to schedule a screening.

The Uncas Health District also participates in the Connecticut Colorectal Cancer Control Program. This program aims to reduce disparities in colorectal cancer by providing free diagnostic services to identify signs that someone might have this cancer. The program is open to qualifying individuals 45 and older, including those with positive results from other colorectal cancer screenings.

 

Screening for Heart Disease

In our work with the Connecticut Breast and Cervical Cancer Early Detection Program, the Uncas Health District also helps identify potential heart disease risk factors. Women in this program can enroll in WISEWOMAN, which provides heart disease screenings for participants between the ages of 35 and 64.

A mammogram not only allows for the detection of potentially cancerous tissue in the breast, but also the presence of breast arterial calcification during mammograms. While this is typically not related to breast cancer, it can be a sign of cardiovascular disease. When breast arterial calcification is detected, it allows for early intervention against heart disease.

 

Take Control of Your Health

Don’t wait. Early detection can save lives. 

If you qualify for any of these programs, please reach out to the Uncas Health District today. Your health is our priority.

Cancer Prevention Month: Taking Action to Reduce Your Risk

Every February, Cancer Prevention Month serves as a reminder that while cancer remains a formidable health challenge, many cases are preventable through lifestyle choices and proactive health measures. With an estimated 2 million Americans diagnosed with cancer (excluding non-melanoma skin cancer) in 2024 and more than 600,000 cancer-related deaths, the urgency for awareness and prevention has never been greater.

The Preventable Nature of Cancer

Research indicates that more than 40% of cancer cases and nearly half of cancer-related deaths stem from preventable causes. These include smoking, excessive body weight, physical inactivity, and overexposure to ultraviolet (UV) radiation. This means that by making informed choices, individuals can significantly lower their cancer risk.

Proactive Steps to Lower Cancer Risk

  1. Quit Smoking (or Never Start) Tobacco use is the leading cause of preventable cancer. Smoking is directly linked to lung, throat, mouth, pancreas, and several other cancers. If you smoke, quitting is one of the most impactful steps you can take for your health. If you don’t smoke, avoiding secondhand smoke is equally important.
  2. Maintain a Healthy Weight Obesity is associated with increased risks of several cancers, including breast, colon, and pancreatic cancer. A balanced diet rich in vegetables, fruits, lean proteins, and whole grains, coupled with portion control, can help maintain a healthy weight.
  3. Stay Physically Active Regular exercise not only helps control weight but also reduces inflammation, regulates hormone levels, and boosts the immune system—all factors that can lower cancer risk. Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous activity each week.
  4. Protect Your Skin from the Sun Skin cancer, including melanoma, is largely preventable. Use sunscreen with an SPF of at least 30, wear protective clothing, and avoid indoor tanning. Limiting direct sun exposure, especially during peak hours (10 a.m. to 4 p.m.), is also key.
  5. Get Vaccinated Certain cancers are caused by infections. The human papillomavirus (HPV) vaccine can prevent cervical, throat, and other cancers, while the hepatitis B vaccine reduces the risk of liver cancer.
  6. Limit Alcohol Consumption Excessive alcohol intake is linked to an increased risk of cancers of the mouth, throat, esophagus, liver, colon, and breast. Moderation is key—guidelines recommend no more than one drink per day for women and two for men.
  7. Get Regular Screenings and Checkups Early detection saves lives. Routine screenings such as mammograms, colonoscopies, and Pap smears can detect cancer at an early, more treatable stage. Consult your doctor about recommended screenings based on your age, family history, and lifestyle.

The Bigger Cancer Prevention Picture

Many diagnosed cancers in the U.S. are considered preventable. While not all can be avoided, taking proactive steps can dramatically reduce risk and improve overall health. This Cancer Prevention Month, commit to small, meaningful changes that can lead to a longer, healthier life.
