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

Launched in 2021, the “Ride or Stride for 45” Virtual Challenge has become an ACG tradition! This virtual experience 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 2021 ACG Clinical Guidelines on Colorectal Cancer Screening (Shaukat, et al.)

About “Ride or Stride for 45” in 2024

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 demonstrate 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 share via social media during this month-long observance.

ACG CRC Community Education Toolkit

The ACG’s ongoing commitment to colorectal cancer awareness includes helping physicians educate their patients and communities about the importance of screening.

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.
