In people younger than 50, colorectal cancer (CRC) is now the leading cause of cancer-related deaths in men and the second in women. Because colorectal cancer is rising in younger adults, current guidelines recommend that regular screening begin at age 45 for people at average risk. Getting screened is critical to detecting and preventing colorectal cancer. Timely screenings can save your life. A variety of different screening methods are available; however, a colonoscopy is the gold standard — the only screening method that can detect and prevent colorectal cancer. There are three different types of colonoscopy, with each one serving a different purpose. To better understand each one, an overview has been provided below.

Screening Colonoscopy
Screening colonoscopy is recommended starting at age 45 for individuals of average risk* of colorectal cancer. Average risk means that the person has no first-degree relatives including father, mother, child and/or siblings or personal history of colorectal cancer or polyps and no history of ulcerative colitis or Crohn’s disease. The goal is to detect precancerous polyps or early cancer before symptoms arise. Procedure is done once every 10 years if the initial exam is normal and if the patient remains at average risk. It is a preventive measure.

Diagnostic Colonoscopy
Diagnostic Colonoscopy is recommended for patients with signs or symptoms consistent with colorectal cancer or to evaluate positive stool or blood-based screening tests. The purpose of investigating symptoms is to diagnose any underlying conditions, such as inflammatory bowel disease or cancer. Symptoms may include the following:
- Bowel changes — Diarrhea, constipation or a feeling that the bowel doesn’t empty completely
- Blood in stool — Can be bright red or dark
- Abdominal pain — Abdominal pain, aches or cramps that do not go away
- Weight loss — Unexplained weight loss
- Fatigue — Feeling tired or weak
- Other symptoms — Frequent gas pains, bloating or abdominal fullness
Positive stool or blood-based screening tests must be evaluated with colonoscopy to exclude cancer or precancerous polyps.

Surveillance Colonoscopy
Surveillance Colonoscopy is recommended for patients if they have had polyps removed in the past or after they have been treated for colorectal cancer. Surveillance Colonoscopy may also be considered for those with ulcerative colitis or Crohn’s disease, requiring more frequent checks than 10 years.
