ACS: Colorectal Cancer Screening

The American Cancer Society (ACS) published a new recommendation regarding colorectal cancer screening on May 30, 2018. ACS now recommends that adults aged 45 years and older with an average risk of colorectal cancer (CRC) undergo regular screening. The current recommendation, including that of the US Preventive Task Force (USPTF), starts at 50 years of age for individuals with an average risk of colorectal cancer. CRC Screening can be preformed by stool-based tests or visual examination of the colon and rectum (e.g. colonoscopy).

Recent studies show that colorectal cancer has been increasing in younger adults. Risk factors associated with a certain lifestyle have been shown to increase CRC risk. These include cigarette smoking, excess body weight, diet with high consumption of alcohol and red and processed meat and low consumption of fruits/vegetables, dietary fiber, and dietary calcium; and physical inactivity.
