A new study presented at Digestive Disease Week 2024 in Washington, DC, reveals that rates of colorectal cancer have dramatically increased among teenagers, children, and young adults between 1999 and 2020. Specifically, the study reports a 500% increase in colorectal cancer cases among children ages 10 to 14, a 333% increase among teens ages 15 to 19, and a 185% increase among young adults ages 20 to 24. Researchers analyzed data from the Centers for Disease Control Wonder Database to track these trends in colorectal cancer rates for individuals aged 10 to 44. In addition, the study found a 71% increase in colorectal cancer cases in adults ages 30 to 34 and a 58% increase in adults ages 35 to 39 during the same period.
Lead researcher Islam Mohamed, MD, emphasized the importance of raising awareness about signs and symptoms of colorectal cancer among the general public, especially since the disease is no longer considered exclusive to the elderly population. While a family history of colorectal cancer remains a risk factor, modifiable risk factors such as regular physical activity and a balanced diet can help prevent the development of the disease. Researchers suggest that the increasing rates of colorectal cancer in younger individuals may be linked to lifestyle factors like obesity, diet high in processed foods, and antibiotic use that can disrupt the microbiome and increase inflammation, factors known to promote cancer development.
Anton Bilchik, MD, PhD, a surgical oncologist, highlighted the importance of prevention strategies such as healthy eating habits, regular exercise, and avoiding pro-inflammatory factors that can contribute to the development of colorectal cancer. Jacqueline Casillas, MD, a pediatric hematologist/oncologist, underlined the need to address risk factors like alcohol consumption, tobacco use, obesity, and sedentary lifestyle in teenagers and young adults to prevent colorectal cancer. While the study shows a significant increase in colorectal cancer rates among young individuals in terms of percentages, it is important to note that the absolute numbers of cases in this age group remain relatively low, indicating that the disease is still uncommon among younger people.
Moving forward, Casillas emphasized the importance of further research to understand the underlying factors contributing to the rise in colorectal cancer cases among teenagers and young adults. By identifying these factors and implementing preventive measures, healthcare professionals can work towards early diagnosis and risk mitigation strategies to combat colorectal cancer in younger populations. The study provides a foundation for future studies to delve deeper into the causes behind the increasing incidence of colorectal cancer in young individuals and develop targeted interventions to address this concerning trend. Expert recommendations include promoting a healthy lifestyle, regular screenings, and raising public awareness about colorectal cancer risk factors and preventive measures to protect individuals from developing the disease at a young age.
