Colorectal Cancer Risk Factors

Several risk factors can increase an individual’s likelihood of developing colorectal cancer. Here are some of the key risk factors:

  • Age: The risk of colorectal cancer increases significantly after age 50, although cases in younger individuals are on the rise.
  • Family History: A family history of colorectal cancer or polyps can increase the risk. Genetic conditions such as Lynch syndrome and familial adenomatous polyposis (FAP) also raise the risk significantly.
  • Personal History of Polyps: Previous adenomatous polyps or colorectal cancer increases the likelihood of developing new cancers.
  • Inflammatory Bowel Disease (IBD): Conditions like ulcerative colitis and Crohn’s disease are associated with an increased risk of colorectal cancer, especially after many years of having the disease.
  • Diet: A diet high in red or processed meats and low in fruits, vegetables, and fiber may contribute to an increased risk.
  • Obesity: Being overweight or obese is linked to a higher risk of developing colorectal cancer, as excess body fat can influence hormone levels and inflammation.
  • Physical Inactivity: Lack of regular physical activity is a risk factor, as it may contribute to obesity and hormonal changes.
  • Smoking: Tobacco use is associated with increased risk for many types of cancer, including colorectal cancer.
  • Alcohol Consumption: Heavy alcohol use is linked to an increased risk of colorectal cancer. Moderate to high amounts of alcohol can be particularly concerning.
  • Type 2 Diabetes: Individuals with type 2 diabetes have a higher risk of developing colorectal cancer, possibly due to insulin resistance and related metabolic changes.
  • Race and Ethnicity: Certain groups, such as African Americans and Ashkenazi Jews, have a higher risk of developing colorectal cancer.

Understanding these risk factors can help individuals make informed decisions about screening, lifestyle choices, and discussing their risks with healthcare providers. Regular screenings are critical for early detection, especially for those with heightened risk factors.

A family history of colorectal cancer or polyps is a significant risk factor because genetic and environmental factors can be passed down through generations, increasing the likelihood of developing similar conditions.

Given the increased risk associated with a family history of colorectal cancer or polyps, families are often encouraged to start screening at an earlier age than the general population and to undergo more frequent screenings. This proactive approach can lead to the early detection of any problems, including the identification and removal of polyps before they develop into cancer.

Understanding Your Colorectal Cancer Diagnosis

Most colorectal cancers are detected during routine screenings, which have become more streamlined, making it easier for you to stay on track with your health. It’s essential to know the types of tests available for early detection of colorectal cancer.

  1. Colonoscopy: This procedure involves using a long, flexible tube with a camera to examine the entire colon and rectum. It’s the most comprehensive screening method and allows for the removal of polyps during the exam.
  2. Flexible Sigmoidoscopy: Similar to a colonoscopy but examines only the rectum and the lower part of the colon. It requires less preparation and can be done in a doctor’s office.
  3. Fecal Occult Blood Test (FOBT): This non-invasive test checks for hidden blood in the stool, which can be a sign of cancer or polyps. It usually requires multiple stool samples over several days.
  4. Fecal Immunochemical Test (FIT): Another stool test that detects blood in the stool using antibodies. It’s more specific than the FOBT and does not require dietary restrictions.
  5. CT Colonography (Virtual Colonoscopy): This imaging test uses X-rays and computer technology to create detailed pictures of the colon. It’s less invasive than a traditional colonoscopy but cannot remove polyps.
  6. DNA Stool Test: This test analyzes stool samples for specific DNA markers that may indicate the presence of cancer or pre-cancerous conditions. It can be more comprehensive in its approach.
  7. Blood Tests: While not used for routine screening, certain blood tests may help assess liver function or detect tumor markers in some cases.


These tests help identify colorectal cancer or pre-cancerous polyps early when treatment is most effective. It’s important to discuss with a healthcare provider which screening method is best suited for individual risk factors and medical history.

Why You Shouldn’t Delay Screening for Colorectal Cancer

Plainly put: Regular screening can save lives!

During the early stages of colorectal cancer, there are typically no visible signs of its presence, making screenings crucial for identifying pre-cancerous and cancerous areas while they are still small. Early detection often leads to fewer treatment demands and greatly increases success rates.

Although it might feel uncomfortable, please don’t shy away from scheduling your screening, especially if you are over 40. Taking this step with your primary care physician can help you create a personalized colon cancer screening plan that is right for you.

Common Colorectal Cancer Screening Methods

Several screening tests are available, ranging from convenient at-home options to more comprehensive procedures performed at healthcare facilities. Your doctor will work with you to select the best method based on your age and family history.

At-Home Screening Options

These tests allow you to screen in the comfort of your home without extensive preparation, though they may carry risks of false positives.

  1. At-Home Testing for Colorectal Cancer: If you are under 50, your physician may recommend at-home testing before scheduling a colonoscopy. This approach lets you complete the test without a day of prior colon preparation. However, it’s essential to note that these tests may overlook some polyps and cancers.
  2. Stool DNA Test: Advances in at-home stool testing, such as Cologuard, have made it easier to conduct Fecal Immunochemical Tests (FIT). This simple test checks for blood and genetic changes without requiring extensive dietary changes.
  3. Guaiac-based Fecal Occult Blood Test (gFBOT): Another home test prescribed by your doctor, gFBOT identifies hidden blood in the stool. If blood is detected, follow-up with a colonoscopy is typically necessary.


Screening at Healthcare Facilities

Screening procedures conducted in medical facilities are often the most accurate and valuable in colorectal cancer detection, allowing for the immediate removal of any suspicious polyps.

  • Standard Colonoscopy: In this procedure, a colonoscope provides detailed images of your colon and allows for tissue removal if abnormalities are found. Proper preparation and sedation are necessary for successful outcomes, and studies show that regular colonoscopies can significantly reduce colorectal cancer mortality rates.
  • Virtual Colonoscopy: Utilizing CT imaging to view your colon, this test usually does not require sedation but does involve bowel preparation. If potential issues arise, a standard colonoscopy may follow for confirmation.


When Should You Be Screened for Colorectal Cancer?

The American Cancer Society (ACS) has recently lowered the recommended screening age from 50 to 45 due to rising colorectal cancer rates among younger adults. Contributing factors may include dietary choices, physical inactivity, and obesity.
Recommended screening frequencies vary based on risk levels:

  • Average Risk: Adults with no family history of colorectal cancer should undergo screenings every ten years.
  • High Risk: Those with a family history, previous inflammatory diseases, or prior radiation exposure to the pelvic area should start screenings earlier and have them more frequently.

Understanding Colorectal Cancer Risk Factors

Like many cancers, various factors influence your risk of developing colorectal cancer—some of which are controllable and others that are not. While no one can predict with certainty if or when colorectal cancer will arise, educating yourself about these risk factors can empower you to take proactive measures to reduce your likelihood of diagnosis.

By staying informed and proactive, you can play an essential role in your health journey and work towards minimizing your risk of colorectal cancer. At El Portal Comprehensive Cancer Centers, we are here to support you with expertise and compassion every step of the way.
