Colorectal cancer is now the leading cause of cancer deaths in people under 50 in the U.S., a new study finds. The incidence and mortality of the disease have been increasing each year since 2004 and 2013, respectively. Most cases are diagnosed at advanced stages, making early diagnosis crucial.
The trend is not limited to the under-50 demographic, with colorectal cancer rates also increasing among adults aged 50 to 64. This rise in early-onset diagnoses is concerning, as it highlights the need for improved awareness and screening methods.
Experts suggest that 'birth cohort effects' and environmental factors like microplastics and ultraprocessed foods may be contributing to the trend. While the exact cause remains unclear, timely screenings and symptom awareness can help prevent many deaths.
Current ACS guidelines recommend starting colorectal cancer screenings at age 45, but only 37% of 45- to 49-year-olds are up-to-date. Increasing awareness can save lives, especially in the younger population.
