If you knew you could prevent cancer, would you? During Colorectal Cancer Awareness Month in March, Dr. John Armstrong, a general surgeon at Buena Vista Regional Medical Center, explains the importance of regular screenings for colon cancer.
“Colon cancer is common, but the good news is that it's one of the cancers we can screen for,” Dr. Armstrong says.
Despite the availability of screening, one in three people in the U.S. who should be screened for colon cancer have never been screened, according to the American Cancer Society.
This is concerning as colorectal cancer is the second leading cause of cancer-related deaths in both men and women in the United States. In fact, one in 24 people will be diagnosed with colorectal cancer in their lifetime.
Thankfully, colorectal cancer screenings can prevent cancer through early detection and the removal of precancerous growths. Colonoscopies are the most common colorectal cancer screening test and can help reduce colorectal cancer cases by 40% and deaths by 60%.
“Colonoscopies may be the greatest tool we have,” Dr. Armstrong states. “Not only for diagnosing colon cancer but also for detecting other issues involving the intestines and the digestive tract.”
Although the idea of a colonoscopy may seem intimidating, it is a common and highly effective preventative procedure. Last fiscal year, BVRMC performed over 750 colonoscopies and is on track to exceed that number for the current fiscal year.
Despite its importance, colonoscopies are often an uncomfortable topic of conversation, leading many people to delay scheduling their screening.
“In reality, it's just a medical procedure,” Dr. Armstrong says. “For us, it's something we do every day. It’s routine, and it’s one of the best ways to prevent colon cancer.”
What Happens During a Colonoscopy?
A colonoscopy is a simple, routine procedure that allows doctors to examine the inside of the colon for abnormalities.
“We use an endoscope, which is essentially a small camera on a flexible cord, and carefully maneuver it through the large intestine, also called the colon, all the way to where it meets the small intestine,” Dr. Armstrong explains.
One of the key goals of a colonoscopy is to find and remove polyps, which are small growths on the inner lining of the colon.
“Polyps are common, and we know that colon cancer starts as polyps,” Dr. Armstrong says. “During a colonoscopy, our goal is to find polyps and remove them—not only to prevent the growth of colon cancer but also to identify individuals who may be more likely to develop polyps in the future.”
Since colon cancer often develops slowly and without symptoms, catching it early—or even preventing it altogether—is crucial.
Colon Cancer Rates are Rising in Younger Adults
In recent years, the number of older adults diagnosed with colorectal cancer has decreased due to increased screenings. However, cases in younger adults are rising.
“The current recommended age to begin colonoscopy screenings is 45,” Dr. Armstrong explains. “However, if someone experiences symptoms or has a family history of colon cancer, we may recommend screening at a younger age. That’s because we’re seeing more cases of colon cancer in younger people.”
Many people assume that if they are healthy and have no symptoms, they don’t need or can delay their colonoscopy. However, even those who live a healthy lifestyle can develop colon cancer. Early detection is key because symptoms often don’t appear until the cancer has progressed.
What Does the Prep Look Like Today?
One of the biggest concerns people have about colonoscopies is the preparation process, which involves dietary restrictions and taking prescribed laxatives to clear the bowels. However, the process has improved significantly.
“In the last few years, colonoscopy prep has changed a lot,” Dr. Armstrong says. “It’s easier than it used to be, and most people tell us that the overall experience of getting a colonoscopy is far better than they expected.”
Convenient Care at BVRMC
The ability to have a colonoscopy locally at BVRMC can be a convenient choice for patients. “We have the convenience of being in closer proximity to people’s homes, making things like transportation and follow-up care easier for patients,” Dr. Armstrong says. “Additionally, if they have any issues or questions, I’m readily available.”
While getting a colonoscopy may not be everyone’s favorite thing to do, raising awareness about colon cancer and the importance of getting a colonoscopy can help save lives. Talking to friends and family about these topics can increase awareness and help put people at ease when scheduling their colonoscopy.
“If people have questions, concerns or any apprehensions, we're happy to speak with them beforehand,” Dr. Armstrong adds.
If you are over the age of 45 or have a family history of colorectal cancer, talk to your doctor about when you should schedule a colonoscopy.
