New research presented at the American Academy of Pediatrics 2026 National Conference highlights that colorectal cancer in children and young adults is often diagnosed at an advanced stage. The study reviewed records of 84 patients aged 21 or younger diagnosed between 2012 and 2023.
Only 20% of these patients had a family history of the disease. Most had already progressed to Stage III or IV by the time of diagnosis. Symptoms such as abdominal pain, changes in bowel habits, unexplained weight loss, and rectal bleeding may be overlooked because colorectal cancer is still uncommon in younger age groups.
The outcomes were severe: more than one-third of patients experienced recurrent disease, and nearly half died. The researchers emphasize that symptoms like rectal bleeding and weight loss should be taken seriously in young people, and that care should be coordinated between pediatric and adult oncology teams.
