Understanding Colon Cancer: The Critical Role of Regular Screenings
Colon cancer follows thyroid cancer as the second most prevalent cancer in South Korea. Often originating from small growths on the inner lining of the colon known as polyps, these seemingly innocuous formations can transform into malignant tumors over time. In 2023, colon cancer-related deaths accounted for 11% of total cancer deaths, ranking as the third leading cause of cancer mortality.
The Root Causes Identified
While there is no single cause that can be blamed, genetic factors appear to play the most significant role. Lifestyle choices, including unhealthy eating habits, lack of physical activity, obesity, excessive alcohol consumption, and smoking, are also contributing factors. The aging population further exacerbates the risk, making prevention and early detection crucial.
Advanced Screening Techniques: The Cornerstones of Early Diagnosis
Colonoscopy is currently the gold standard for screening and diagnosis. This procedure allows doctors to directly inspect the colon’s lining and polyps with their own eyes. There are two primary forms of colonoscopy: diagnostic and therapeutic. The former focuses on detection, while the latter incorporates treatment by removing detected polyps during the procedure.
Did you know? There are two main therapeutic colonoscopy techniques: Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD). EMR is typically used for smaller polyps, utilizing tools to safely remove them. ESD, however, can address larger polyps by isolating and removing them along with deeper tissue layers. This thorough approach helps minimize the risk of recurrence and allows for a precise evaluation of potential cancer progression.
Case Study: Successful Outcomes with Regular Screening
Experts at the Kyung Hee University Asan Hospital, such as Professor Kim Dong-Woo from the Department of Gastroenterology, emphasize the importance of removing even non-cancerous polyps due to their potential to transform. “While curing polyps before they become malignant is ideal, it’s important to not overestimate the benign nature of non-cancerous growths,” Professor Kim advises.
Lifestyle Adjustments to Reduce Risk
Though not entirely preventable, significant prevention steps can be taken. Experts advise dietary adjustments like reducing red meat and processed meats, and increasing fiber-rich foods such as vegetables and whole grains. Regular exercise and smoking cessation also significantly lower the risk of developing colon polyps and cancer.
