Colorectal cancer (CRC) is a significant health concern in the United States, ranking as the third most common cancer and the second leading cause of cancer-related deaths. In 2023 alone, an estimated 153,020 new cases will be diagnosed, with 52,550 lives lost to this disease.
Alarming Rise in Early-Onset Cases
While CRC has traditionally been associated with older individuals, a disturbing trend is the increasing incidence in younger people. In 2019, a staggering 20% of CRC cases were diagnosed in individuals aged 54 or younger, a significant increase from 11% in 1995. This shift is particularly concerning as it often leads to diagnoses at later stages, impacting survival rates.
Screening: A Crucial Tool in Prevention
Regular screening plays a pivotal role in early detection and prevention of CRC. The American Cancer Society recommends that screening begin at age 45. However, screening rates remain suboptimal, particularly among younger age groups, Asian Americans, and individuals with lower education levels or without insurance.
Geographic Variations
The incidence and mortality rates of CRC vary significantly across the United States. The highest rates are concentrated in parts of the South, Midwest, and Appalachia, while the lowest rates are observed in the West.
The Importance of Early Detection
Early detection through screening and timely intervention are crucial in improving survival rates for CRC. The 5-year relative survival rate for CRC has increased from 50% in the mid-1970s to 65% during 2012-2018.
