MedStar Health Finds 79% of People Polled are Unaware of when to get a Colonoscopy

National survey conducted in recognition of Colorectal Cancer Month in March.

COLUMBIA, Md., March 3, 2025 /PRNewswire/ -- A national survey conducted by MedStar Health to gauge the public's knowledge of screening guidelines for colorectal cancer, revealed 79% of the respondents don't know when to get a colonoscopy, and only 9% could identify the signs and symptoms of colorectal cancer. Younger people under the age of 45 appear to be the least informed about colon cancer and colonoscopy. The 15-question survey, recognizing the importance of March's Colorectal Cancer Awareness Month, was designed to identify gaps in knowledge to target education efforts and to promote early detection.

Other key survey findings include:

• 38% of people 45+ have not had a colonoscopy; about a quarter of adults 45+ (26%) do not plan on getting a colonoscopy in the future
• Of those who have had a colonoscopy, 93% say it was better than or as they expected
• 20% of people 45+ said they put colonoscopies off because of the preparation before the procedure
• Only 21% know how often to have colonoscopy for people with average risk (every 10 years)
• 31% of people 45+ haven't discussed colonoscopy with their doctor
• Younger adults (under 45) are the most misinformed about colonoscopies, but are generally concerned about colorectal cancer:
  • 36% believe they need their first colonoscopy at age 35 or younger.
  • 24% believe they need to get a colonoscopy every year.
  • Only 33% are aware of colonoscopy alternatives.
  • 28% are very concerned about colorectal cancer (70% very or somewhat concerned).

"The survey findings highlight a critical need for education on colon health," said Dana Sloane, MD, medical director of the Center for Digestive Disease at MedStar Franklin Square Medical Center. "It's concerning that 79% of people are unaware of the recommended age to begin colonoscopy screenings, which is 45 for those at average risk. Early detection is key in preventing and treating colorectal cancer, and yet a significant portion of individuals, especially those over 45, are delaying or avoiding this important test due to misconceptions or fears about the procedure. We hope this survey sheds light on the importance of being informed, especially since most individuals who undergo a colonoscopy report having a positive experience."

"It's essential that we all do our part to increase awareness of colonoscopy guidelines and alternatives, so individuals can make informed decisions about their health and potentially save their lives," added Priyanka Kanth, MD, gastroenterologist and director of the Gastrointestinal Cancer Prevention Program at MedStar Georgetown University Hospital. "We encourage everyone, especially those over the age of 45, to have open conversations with their healthcare providers and stay proactive in their colorectal cancer screenings. The earlier we detect any issues, the better the chances are for successful treatment and outcomes."

Colonoscopies help detect early signs of cancer, often before symptoms appear. Early detection can lead to more successful treatment and significantly improve survival rates. For individuals at average risk, colonoscopies should be done every 10 years. However, your doctor might recommend more frequent screenings if you have risk factors, such as a family history of colorectal cancer or polyps.

While colonoscopy is the most common screening method, there are alternatives like stool tests (e.g., FIT, Cologuard) and sigmoidoscopy. These options may be less invasive, but colonoscopy remains the gold standard for thorough examination.

Studies show that colorectal cancer often develops slowly over time, starting as non-cancerous growths called polyps. By removing these polyps during a colonoscopy, doctors can prevent cancer from developing, making screening a powerful tool in prevention.
