How Colonoscopy Screenings Help Prevent Colon Cancer

Orlando Lopez-Roman, MD

KEY WEST, Fl, MARCH 13, 2026 – March is Colorectal Cancer Awareness Month. According to the American Cancer Society, colorectal cancer is the third-leading cause of cancer-related deaths for men and the fourth leading cause in women in the United States. Despite being preventable and treatable, many individuals still die from this disease due to a lack of awareness about preventive care. 
  
Lower Keys Medical Center is committed to promoting early detection and prevention of colon cancer through regular colonoscopy screenings because, when detected early, the survival rate for colon cancer is approximately 90%. 
 
During the procedure, doctors examine the colon for pre-cancerous polyps, which can be removed during the same process, reducing the risk of developing colon cancer in the future. They can also screen for cancer. This is important, as studies show those who undergo regular screenings are less likely to die from colon cancer. 
 
Many people fear that there might be discomfort and pain associated with a colonoscopy. However, it’s important to know that patients are under monitored anesthesia – asleep but breathing on their own. 
  
“Some people may hesitate to schedule a colonoscopy, but they are essential for early detection and prevention of colon cancer,” said Orlando Lopez-Roman, MD, board-certified gastroenterologist, at Keys Medical Group Gastroenterology. “Don’t delay in getting this life-saving procedure done.” 
  
Colonoscopy screening should start at 45 for those at average risk, with regular screenings continuing every 10 years. However, the screening frequency and start date may differ for individuals at higher risk of developing the disease, as colorectal cancer incidence is higher in certain populations, including Black and Indigenous adults, Jews of Eastern European descent, and people with a family history of colorectal cancer and men. 
  
Age also plays a big factor when it comes to risk. On average, those 50 and older are the most likely to suffer from colorectal cancer, although it is rising among people younger than 50. 
  
While age and family history cannot be changed, there are several lifestyle factors that you can modify to lower your risk, including losing weight, maintaining a healthy diet, limiting alcohol, quitting smoking and exercising regularly.  
  
“Colonoscopies have revolutionized how we detect and prevent colon cancer. With advancements in technology – such as Lower Keys Medical Center's AI-assisted endoscopy device which helps us identifyabnormalities and polyps – and improved patient comfort, there’s never been a better time to prioritize your colon health,” said Dr. Lopez-Roman. “Early detection is key, and a screening colonoscopy could save your life.” 
  
Talk to your healthcare provider about your risk level and the appropriate timing and frequency of screenings. Remember, you’re never too young to take charge of your health.
