Colonoscopy Screening & Procedure

Find a Specialist Near You


A colonoscopy can be done as a screening for colon cancer, as well as other gastrointestinal issues, such as crohn’s disease, irritable bowel syndrome or colitis. In fact, a colonoscopy screening is the number one tool to help detect early signs of cancer. It also allows your doctor to remove polyps that over time can become cancerous.


A colonoscopy screening can help your doctor:


  • Look for signs of cancers and other problems
  • Explore the cause of unexplained changes in bowel habits
  • Evaluate symptoms of pain or bleeding located in the abdominal area
  • Find a reason for weight loss, chronic constipation or diarrhea


Our highly skilled gastroenterologists annually perform tens of thousands of colorectal screenings and almost always remove polyps at the time of diagnosis.


The American College of Gastroenterology recommends patients receive a colonoscopy if:


  • You are 50 years of age or older
  • You are African American and 45 years of age or older
  • You are 40 years old or 10 years younger than the age at which a first degree relative was diagnosed with colon cancer


In most cases, your doctor will refer for a colonoscopy. In some cases, however, if you meet certain criteria, you can schedule your colonoscopy directly. Houston Methodist West and Houston Methodist Hospital offer direct scheduling by calling the phone numbers below. All other campuses require you to first see your doctor for a referral. Due to recent changes in screening recommendations, please consult your insurance provider to confirm coverage if you are under the age of 50.
