Many people still dread the thought of undergoing a colonoscopy, but the reality is, it could be the most life-saving procedure one might ever need. Colorectal cancer ranks as the fourth most common cancer among both men and women, trailing only behind skin cancers. According to Dr. Kimberly Kolkhorst, gastroenterologist at Essentia Health, early detection can save lives. "While you might have heard negative things about the process of getting a colonoscopy, the reality is for most people the procedure is easier than they realize and brings peace of mind," she states.
Why are colonoscopies regarded as the gold standard for colorectal cancer screening? The primary reason lies within their ability to both detect and prevent cancer. Unlike other screening methods, colonoscopies not only identify abnormalities but also allow healthcare providers to remove precancerous polyps during the examination. Most colorectal cancers begin as these precancerous growths, and by removing them via colonoscopy, potential cancer cells are stopped before they develop.
Colonoscopies boast approximately 95% accuracy, making them the most effective tool for colorectal cancer detection. "Other colorectal cancer screening options include testing your stool for signs of cancer,” explains Dr. Kolkhorst. “These tests are not as accurate as a colonoscopy and have the risk of false positives.” Hence, the best course of action is to undergo this procedure when due. If results are normal, patients may not need to repeat the colonoscopy for ten years. The American Cancer Society also recommends starting regular screenings at age 45 for those at average risk.
Preparing for the procedure can seem intimidating, but the process can be managed effectively with the right approach. About three days before the colonoscopy, participants are advised to follow a low-fiber diet, which includes animal proteins, cooked vegetables, and selected fruits. Two days prior, one must cease solid foods and focus on clear liquids only: clear broth, certain juices, and clear sports drinks are permitted, along with popsicles and gelatin, except for those with coloring agents which may stain the colon lining.
On the day before the colonoscopy, patients will typically need to take laxatives to cleanse the bowel. Diarrhea will occur as the preparation takes effect, making it wise to stay home and close to facilities. Dr. Kolkhorst acknowledges, "Bowel prep is probably the least desired part of the colonoscopy experience for many people.” Nevertheless, preparation is key to ensuring the best outcome during the procedure.
On the day of the exam, individuals will likely not be allowed to eat or drink anything. They will arrive at the hospital, where they will change to hospital attire and have their vitals checked by nursing staff. A strong sedative will be administered to help moderate pain and anxiety, often resulting in blurry memories of the procedure. During the colonoscopy, the provider will insert the colonoscope through the rectum to view the interior of the colon, inflowing air when necessary for visibility and taking biopsies if needed.
Post-procedure, patients are usually able to resume their regular diet, but due to the sedative, arrangements should be made for someone to drive them home afterward. Following healthcare providers’ instructions carefully leads to successful outcomes during the entire process.
Here lies the importance of proactive health measures: colorectal cancer is often symptomatic only once it has advanced significantly, reducing treatment efficacy. The opportunity to detect risks before symptoms manifest cannot be overstated. It serves as both personal and collective responsibility among communities to raise awareness about the necessity of screenings and following the recommendations laid out by healthcare professionals.
Dr. Kolkhorst concludes, "It takes one day to get this done, and it can truly save your life!" Therefore, taking the step to schedule and prepare for this important examination is not just wise but invaluable. Ignoring it can lead to adverse outcomes, making the consideration of this procedure entirely worthwhile.
