March is National Colorectal Cancer Awareness Month - a time to raise awareness about colorectal cancer (CRC), the fourth most common and second deadliest cancer in the United States. Despite its severity, CRC is highly preventable through screening, making it imperative to encourage screenings for individuals starting at age 45.
In honor of National Colorectal Cancer Awareness Month 2025, this Guideline Spotlight will focus on the Colorectal Cancer Screening Guidelines Toolkit, which compares the current CRC screening guidelines. This toolkit provides a concise overview of key similarities, differences, and crucial points, serving as a valuable resource for healthcare professionals. It also highlights related resources for colorectal cancer.
Over the years, more than half a dozen clinical practice guidelines for CRC screening have been published in the US While these guidelines often align on key issues, discrepancies exist. These variations arise from differences in guideline scope, methodology, age recommendations, literature review timelines, and the perspectives of various medical specialties, including primary care, oncology, gastroenterology, and government agencies.
This discussion will briefly outline the toolkit’s key points. Please note that this overview doesn’t cover all aspects. To explore the full toolkit, click here, and to access the patient summary, click here.

Similarities and Differences in CRC Guidelines
Healthcare providers should be aware of both the commonalities and discrepancies within CRC screening guidelines. Key similarities include:
- Age and Risk: Most guidelines agree that individuals under 45 should be screened if they are at higher risk for CRC. Screening is generally recommended to stop at age 75 for the majority of patients, with a cutoff at age 85 for nearly all.
- Screening Intervals: Guidelines typically agree on the recommended intervals for CRC screening.
However, differences exist in several areas:
- Screening Age for Average-Risk Individuals: Older guidelines recommend screening start at age 50, while the latest guidelines advocate for beginning at age 45.
- First-Line Screening Tests: Some guidelines favor specific tests, while others promote shared decision-making between the patient and healthcare provider.
Key Areas of Variation in CRC Screening Guidelines
Additionally, the toolkit provides insight on the following areas of discrepancy among guidelines:
- Testing frequency and protocols
- Optimal timing for initiating and discontinuing screening
- Screening recommendations for different risk groups (average risk, high risk, older adults)
- Shared decision-making and patient adherence
- Barriers to testing and strategies for overcoming them
In conclusion, it is important for healthcare providers to know both the similarities and differences in CRC screening guidelines in order to deliver top-notch care to their patients. By remaining informed about the most recent recommendations, providers can guarantee that their patients undergo timely and suitable screenings, ultimately enhancing outcomes and lessening the burden of colorectal cancer. This toolkit provides healthcare professionals with invaluable insights and strategies to effectively navigate the intricacies of CRC screening and provide optimal patient care.
