In this post I link to and excerpt from some colon cancer screening resources.
1. The Colorectal Cancer Risk Assessment Tool from The National Cancer Institute, accessed 11-16-2020:
The Colorectal Cancer Risk Assessment Tool was designed for doctors and other health care providers to use with their patients. The tool estimates the risk of colorectal cancer over the next 5 years and the lifetime risk for men and women who are:
- Between the ages of 45 and 85
- White
- Black/African American
- Asian American/Pacific Islander
- Hispanic/Latino
This tool takes about 5 minutes to complete.
There is not as much data available for blacks/African Americans, Asian Americans/Pacific Islanders, or Hispanics/Latinos. Until researchers complete additional studies to provide more information about these groups, their results may be less accurate. While the tool is not perfect, it can still help doctors and their patients better understand personal risk of colorectal cancer.
This tool does not currently apply to American Indians and Alaska Natives; however, we plan to improve the tool for use by these groups.
This tool cannot accurately estimate risk of colorectal cancer for people who have the following health conditions:
- Ulcerative colitis
- Crohn disease
- Familial adenomatous polyposis (FAP)
- Hereditary Nonpolyposis Colorectal Cancer (HNPCC), also known as Lynch Syndrome
- Personal history of colorectal cancer
2. Draft Recommendation Statement
Colorectal Cancer: Screening*
October 27, 2020 from the U.S. Preventive Services Task Force
See Current Final Recommendation Statement for Colorectal Cancer: Screening(2016)
What follows is all from the 2020 Draft Recommendation Statement above:
Recommendation Summary
Population Recommendation Grade Adults ages 50 to 75 years The USPSTF recommends screening for colorectal cancer in all adults ages 50 to 75 years. See the “Practice Considerations” section and Table 1 for details about screening strategies. A Adults ages 45 to 49 years The USPSTF recommends screening for colorectal cancer in adults ages 45 to 49 years. See the “Practice Considerations” section and Table 1 for details about screening strategies. B Adults ages 76 to 85 years The USPSTF recommends that clinicians selectively offer screening for colorectal cancer in adults ages 76 to 85 years. Evidence indicates that the net benefit of screening all persons in this age group is small. In determining whether this service is appropriate in individual cases, patients and clinicians should consider the patient’s overall health and prior screening history. C
Assessment of Magnitude of Net Benefit
The USPSTF concludes with high certainty that the net benefit of screening for colorectal cancer in adults ages 50 to 75 years is substantial.
The USPSTF concludes with moderate certainty that the net benefit of screening for colorectal cancer in adults ages 45 to 49 years is moderate.
The USPSTF concludes with moderate certainty that the net benefit of screening for colorectal cancer in adults ages 76 to 85 years who have been previously screened is small. Adults who have never been screened for colorectal cancer are more likely to benefit.
