Colonoscopy Set to Become a Cornerstone of Korea‘s National Cancer Screening Program,Experts Advocate for Expanded Access

Seoul,South Korea – A notable shift is on the horizon for South Korea’s fight against colorectal cancer. Following a public hearing convened by the National Cancer Center, a proposal has emerged to actively expand colonoscopies within the nation’s free cancer screening project. This move, driven by accumulating scientific evidence and a changing medical landscape, aims to bolster early detection and prevention efforts for a cancer that remains a leading cause of mortality in the country.The current iteration of the national screening guidelines, last updated in 2015, primarily focuses on faecal occult blood tests (FOBT) for asymptomatic adults aged 45 to 80, recommended every one to two years. Colonoscopy, while recognized as a more definitive diagnostic tool, was historically reserved for individuals wiht higher perceived risks or personal preferences, largely due to concerns about the “small benefits” weighed against potential complications.

However, a panel of experts, comprising medical professionals and consumer advocates, has concluded that the benefits of regular colonoscopies far outweigh the risks. This consensus has led to a pivotal recommendation: colonoscopy should transition from a selective option to a fundamental component of colorectal cancer screening.

The proposed guidelines suggest a 10-year interval for colonoscopies for eligible individuals, a measure deemed sufficient by the review committee to effectively monitor for cancerous or precancerous polyps. the existing recommendation for FOBTs, to be conducted every one to two years, will remain in place.

A notable adjustment in the revised recommendation is the narrowing of the target age range for screening to 45-74 years old, a reduction from the previous 45-80 age bracket for FOBT.The national Cancer Center clarified that thes recommendations are intended to establish a minimum screening standard for asymptomatic adults.

This proposed inclusion of colonoscopy into the national screening framework represents a significant departure from current practice. Presently, the National Health Insurance Corporation’s coverage primarily supports individuals over 50, and even then, colonoscopies are typically provided only upon detection of abnormalities in initial screenings like FOBTs.

Director Yang Han-gwang of the national Cancer Center expressed optimism about the potential impact, drawing parallels to the success of gastroscopies in substantially improving early detection rates for stomach cancer, reaching an notable 70%. He believes that integrating colonoscopies into the national screening program could mark a similar “significant turning point” in preventing colon cancer and enhancing early detection.

The implications of this potential policy change are substantial, especially considering the persistent burden of colorectal cancer in South Korea.In 2023, the National Statistical Office reported 9,348 deaths from colon cancer, accounting for 11.0% of all cancer-related fatalities. This places it as the third leading cause of cancer death,following lung cancer and liver cancer.

The National Cancer Center will now undertake further review and confirmation of these crucial recommendations. Should they be formally adopted, this proactive approach to expanding colonoscopy access promises to be a vital step forward in the nation’s ongoing efforts to combat colorectal cancer and improve public health outcomes.

Key takeaways for archyde.com readers:

Colonoscopies gaining prominence: Korea’s national cancer screening is likely to see a significant expansion of colonoscopy services. Shift in expert opinion: Experts now advocate for colonoscopy as a core screening tool, not just an option for high-risk individuals.
Proposed schedule: A 10-year interval for colonoscopies is recommended, alongside continued faecal occult blood tests every 1-2 years.
Age range adjustment: The target age for screening may be adjusted to 45-74.
Public health impact: This change aims to drastically improve early detection and combat the high mortality rate associated with colorectal cancer in Korea.
future outlook:* The National Cancer Center will conduct further reviews before formal adoption.

What are the key reasons for the shift in recommended colorectal cancer screening age from 50 to 45?

Understanding the Latest Guidelines for Colon Cancer Prevention

Colorectal cancer remains a meaningful health concern, but advancements in screening technologies and a deeper understanding of risk factors have led to updated guidelines over the past decade. This article,updated for 2025,provides a comprehensive overview of colorectal cancer screening recommendations for adults aged 45-74,focusing on the most effective methods for early detection and prevention. We’ll cover everything from screening options to preparation and follow-up care, empowering you to make informed decisions about your health. key terms include colorectal cancer screening, colon cancer prevention, colonoscopy, fecal immunochemical test (FIT), Cologuard, and polyps.

Why the Age Shift? screening Starting at 45

For years, screening recommendations began at age 50. Though, rising incidence rates of colorectal cancer, particularly among younger adults, prompted the American Cancer Society and othre leading organizations to lower the recommended starting age to 45 in 2018. This change reflects a concerning trend of increased diagnoses in individuals under 50, highlighting the importance of earlier and more frequent colon cancer screening. Factors contributing to this shift include changes in diet, lifestyle, and perhaps, the gut microbiome.

Available Screening methods: A Detailed comparison

several effective methods are available for colorectal cancer detection. The best option for you will depend on your individual risk factors, preferences, and access to healthcare.

Colonoscopy: Considered the gold standard, a colonoscopy involves inserting a flexible tube with a camera into the rectum to visualize the entire colon. It allows for the detection and removal of polyps – precancerous growths – during the procedure. Requires bowel preparation. Screening interval: every 10 years if results are normal.

Fecal Immunochemical Test (FIT): A simple, at-home test that detects hidden blood in stool.Annual testing is required. A positive FIT result necessitates a follow-up colonoscopy. Excellent for population-wide screening due to accessibility.

Stool DNA Test (Cologuard): Also performed at home, Cologuard analyzes stool for both blood and abnormal DNA markers associated with colorectal cancer and advanced polyps. Requires testing every 3 years.A positive result requires a follow-up colonoscopy.

Flexible Sigmoidoscopy: Examines only the lower portion of the colon (sigmoid colon). Less invasive than a colonoscopy, but doesn’t visualize the entire colon. screening interval: every 5 years, often combined with annual FIT testing.

CT Colonography (Virtual Colonoscopy): Uses a CT scan to create images of the colon. Requires bowel preparation. Screening interval: every 5 years if results are normal. If polyps are detected, a traditional colonoscopy is needed for removal.

Understanding Your Risk Factors for colorectal Cancer

While everyone aged 45-74 should consider screening,certain factors increase your risk and may warrant earlier or more frequent testing. These include:

Family History: A strong family history of colorectal cancer or advanced polyps substantially increases your risk.

Personal History: Previous diagnosis of colorectal cancer or certain types of polyps.

Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease and ulcerative colitis increase risk.

Genetic Syndromes: Lynch syndrome and familial adenomatous polyposis (FAP) are inherited conditions that dramatically elevate risk.

Lifestyle Factors: A diet high in red and processed meats,obesity,smoking,and lack of physical activity are associated with increased risk.

Preparing for Your Screening: What to Expect

Proper preparation is crucial for accurate results, especially for colonoscopy and CT colonography.

Colonoscopy Preparation: Typically involves a clear liquid diet for 1-3 days before the procedure, along with a bowel cleansing regimen (laxatives) to empty the colon.

CT Colonography Preparation: Similar to colonoscopy prep, requiring a clear liquid diet and bowel cleansing.

FIT and Cologuard: These tests require collecting a stool sample at home, following the provided instructions carefully.

what Happens After Screening? Follow-Up and Management

Normal Results: Follow the recommended screening interval based on the method used.

Polyp Detection: Polyps removed during a colonoscopy are sent for biopsy to determine if they are precancerous.Follow-up colonoscopies will be scheduled based on the number, size, and type of polyps found.

Positive FIT or Cologuard: A colonoscopy is required to investigate the source of the blood or abnormal DNA.
