colorectal cancer earlier , at more treatable stages . The American Cancer Society , in 2018 , published updated guidelines with a recommendation to lower the starting age for CRC screening to 45 from 50 years of age , while the U . S . Preventive Services Task Force ( USPSTF ) maintained the 50-year age goal . 5 One advantage of initiating earlier screening is reducing risk of CRC due to earlier detection , which over time would , ultimately , reduce incidence in those age 50 and older . 6
The gold standard for CRC screening is a colonoscopy performed by a gastroenterologist every 10 years , or more frequently depending on findings . Non-invasive screening also exists and have been proven to reduce CRC deaths . 7 These include fecal immunochemical test ( FIT ) or guaiac-based fecal occult blood tests ( gFOBT ), which are collected at home and analyze blood in stool . 8 These should be performed yearly and positive testing on either of them should lead to further surveillance with colonoscopy . Other options exist such as stool DNA testing , CT colonography ( imaging modality ) and double-contrast barium studies . Despite the numerous modalities to screen for CRC , nearly one-third of the U . S . population is unscreened ; 6 therefore , it is important to tailor screening based on individual patient characteristics , preferences and medical history .
Health care providers play a pivotal role in guiding individuals towards lifestyle choices that can markedly lower their risk of colorectal cancer . Emphasizing the importance of a diet abundant in fiber , fruits and vegetables , while minimizing the consumption of red and processed meats , is paramount . Advocating for regular physical activity and discouraging tobacco use are equally important .
Colorectal Cancer Awareness Month serves as a timely reminder for medical providers to reinforce the importance of early detection through screening and to advocate for lifestyle modifications that mitigate the risk of colorectal cancer . By staying informed about the evolving landscape of CRC prevention and treatment , health care professionals can enhance their role as advocates for patient well-being and contribute to the ongoing efforts to reduce the burden of this prevalent malignancy .
