Rising Rates of Colorectal Cancer Among Young Adults: New Report
Colorectal cancer (CRC) has now become the leading cause of cancer deaths in adults under 50, according to a new report from the American Cancer Society. While the rates of this disease have been decreasing among older adults, a concerning trend shows that younger adults, particularly those aged 20 to 49, are experiencing an increase in diagnoses.
The report, titled Colorectal Cancer Statistics, 2026, reveals that nearly half of all new colorectal cancer cases—about 45%—are found in adults aged 65 and younger. This marks a significant rise from just 27% in 1995. Notably, adults between the ages of 20 and 49 are seeing the fastest growth in CRC cases, with a yearly increase of around 3%.
For adults aged 50 and under, it’s alarming that 75% of colorectal cancers are diagnosed at advanced stages. Most diagnoses occur between the ages of 45 and 49. Despite being eligible for routine screenings, only 37% of individuals in this age group participate in necessary screening tests.
The report also highlights a rising trend in rectal cancer, which now comprises about one-third (32%) of all CRC cases, up from 27% in the mid-2000s. Rebecca Siegel, the senior director of surveillance research at the American Cancer Society, emphasized the need to understand the reasons behind this rise. She mentioned, “After decades of progress, the risk of dying from colorectal cancer is increasing among younger generations, indicating a real upsurge due to unknown factors or exposures.”
Experts stress the importance of early detection and awareness. It’s projected that this year will see around 158,850 new colorectal cancer cases, with an estimated 55,230 deaths resulting from the disease. More than half of these cases are connected to factors like poor nutrition, high alcohol consumption, smoking, lack of exercise, and obesity.
Dr. William Dahut, a leading scientist at the American Cancer Society, stated, “These findings underline the urgent need for screening to start at age 45 for those at risk.”
The report also highlights that when caught at an early stage, the five-year survival rate for colorectal cancer is a promising 95%. Continued research funding is critical to developing new treatments and improving care for those affected.
As awareness of these rising rates increases, health advocates recommend that eligible adults pay closer attention to screening guidelines and familiarize themselves with the symptoms of colorectal cancer.
This shift in the landscape of colorectal cancer underscores a growing health concern that warrants immediate attention and action from both medical professionals and the public.
