Colonoscopies Save Lives: Here’s the Proof

Colonoscopies Save Lives

Colonoscopies save lives. It is a fact. In recent months news spread quickly regarding a study published in the New England Journal of Medicine that suggested colonoscopies may not be as effective at reducing cancer deaths as previously thought. Regardless of the news stories, this one study’s findings should not deter you or anyone from getting checked for colorectal cancer. Many studies have been done to show how effective colonoscopy is in early cancer detection and prevention.

Colonoscopies remain the gold standard with advancements in equipment, preparation guidelines and training. Since colorectal cancer is the second deadliest form of cancer, we want you to understand that it is imperative that you remove any thoughts on delaying or ignoring talking to a physician about colorectal cancer screening.

Here is more information on the recent study, the media coverage and some things to consider about colorectal cancer screening.

Colonoscopy Study Details

  • Followed 85,000 people living in four countries in Europe
  • One third received a letter inviting them to have a colonoscopy, the others received no colorectal cancer screening
  • 10 years later, colon cancer risk was 18% less in the invited group and there was no difference in colorectal cancer deaths between the groups

Colonoscopy Study Considerations

  • Less than half (42%) of those invited to have a colonoscopy had one
  • The study covers a European population which is less diverse than the American population
  • Diets in European countries are different as compared to American diets
  • In those who had a colonoscopy within the study:
  • The risk of developing colorectal cancer decreased by 18%
  • The risk of dying from colorectal cancer decreased by 50%

Current National Colonoscopy Screening Guidelines

National Guidelines for colorectal screening have not changed. The American College of Gastroenterology recommends colorectal screenings in average risk individuals starting at 45 years of age, repeating at maximum every 10 years, up until the age of 75. After the age of 75, it is best to talk to your physician about how to proceed with screenings.

Colorectal cancer screening may be recommended sooner for the following:

  • Individuals with inflammatory bowel disease (including ulcerative colitis and Crohn’s disease)
  • Members of certain ethnicities (African Americans have a higher chance of getting colon cancer than individuals of other ethnicities)
  • Individuals with a history of bowel cancer or polyps in their immediate family
  • Individuals with a diet that is low in fiber but high in fat and calories

If you have questions or concerns, you should talk with a specialist in digestive health to understand your risk of colon cancer and to receive recommendations on when to plan a colonoscopy screening.

Know the Warning Signs of Colorectal Cancer

People with colorectal cancer report varying degrees of signs and symptoms. They include the following:

  • Frequent change in bowel movements
  • Rectal bleeding or bloody stool
  • Frequent abdominal discomforts, such as cramps, gas or pain
  • A feeling that your bowel cannot empty fully
  • Weakness or fatigue
  • Unexplained weight loss

Some individuals report feeling no symptoms at all which makes following the national screening guidelines crucial.

Colonoscopies Save Lives by Preventing Cancer

Colonoscopies Save Lives by Preventing Cancer from Developing

Polyps that form in the colon are removed when your doctor finds them during the colonoscopy. Polyps eventually turn into cancer. Removing them as soon as they are found stops cancer from developing. Polyps are more common in people over age 45 – simply because of aging. Polyps are also more common in people with underlying risk factors, like a family history of colon cancer, and for people with lifestyle risk factors like smoking or being obese.

Polyps generally turn into cancer slowly. This is why colonoscopies are performed every 10 years in people of average risk. If your doctor finds and removes polyps, then you will usually need more frequent colonoscopies.

Colonoscopies Save Lives by Detecting Cancer Early

Sometimes, a polyp may have already turned into cancer by the time you have a colonoscopy. If colon cancer is found early, the chances of it being treatable are much higher. People who have a colonoscopy because they are experiencing symptoms are more likely to have more severe cancer. Usually this is because early-stage cancer often has no physical symptoms.

Colon cancer that is found early has a 90% survival rate for 5 years. That number goes down to only 15% if it is found at a later stage and has already spread to other parts of the body. This is proof that colonoscopies save lives.
