A Healthy Challenge to Promote Colorectal Cancer Screening Starting at Age 45 for March Colorectal Cancer Awareness Month in 2023!

For 2023, an ACG tradition continues with the “Ride or Stride for 45” Virtual Challenge! This event brings together the ACG family and GI community to show their commitment to colorectal cancer screening and prevention and highlight age 45 to begin colorectal cancer screening for all average risk adults, as recommended in the updated 2021 ACG Clinical Guidelines on Colorectal Cancer Screening (Shaukat, et al.)

About “Ride or Stride for 45” in 2023

In this virtual event, ACG members, your patients, families and friends are all invited to bike, run or walk 45 miles in March (or 45 minutes per day during the month) to show your support and enthusiasm for preventing colorectal cancer beginning at age 45 for all average-risk adults.

The American College of Gastroenterology urges you to get some exercise, share the message of colorectal cancer prevention, and connect via social media during this monthlong observance. Proceeds of this event will benefit the ACG Institute for Clinical Research & Education.

Your Call-to-Action

  • Put your commitment to colorectal cancer prevention to the test and bike, run or walk 45 miles total in March….OR 45 minutes per day during the month!
  • Celebrate your success and urge your patients, families, and communities to get screened for colorectal cancer starting at age 45.
  • ACG reminds everyone that: Now “45 is the new 50” to start screening for everyone at average risk for colorectal cancer! Your gastroenterologist can find colon polyps early so they can be safely removed and help to prevent colorectal cancers.

Patient Information: “45 is the New 50” ACG’s New CRC Screening Age

Age 45 is now recommended as the time to start screening for colorectal cancer among all average-risk adults according to 2021 guidelines from the American College of Gastroenterology. Your gastroenterologist can find colon polyps early so they can be safely removed and help to prevent colorectal cancers.

In the United States, colorectal cancer is the third most common cancer, yet it is one of the most preventable types of cancer. It is highly treatable and is often curable when caught early.

The American College of Gastroenterology is dedicated to the early detection and prevention of colorectal cancer. Our experts know that colorectal cancer screening tests can save lives.
