Santa Monica, California – Recent research has indicated a concerning trend in the rise of colorectal cancer cases among young people. Not only are cases increasing in younger adults, but data now shows a significant uptick in cases among children as well.
A new 22-year analysis of data from the Centers for Disease Control and Prevention revealed alarming increases in colorectal cancers in kids between 1999 and 2020. The study found that the rate of colorectal cancers grew by a staggering 500% in kids ages 10 to 14, 333% in teens ages 15 to 19, and 185% in young adults ages 20 to 24. These findings will be presented at Digestive Disease Week later this month.
Although the overall numbers of cases remain low, with just 0.6 children ages 10 to 14 per 100,000 diagnosed with colorectal cancer in 2020, compared to 0.1 per 100,000 in 1999, doctors emphasize the importance of monitoring these increases. Dr. Tiago Biachi, a medical oncologist at Moffitt Cancer Center, considers these findings to be concerning and urges parents to be aware of the risks.
While the reasons behind the rise in colorectal cancer cases among young people remain unclear, experts suggest that lifestyle factors, such as obesity, processed diets, sedentary lifestyles, and gut microbiome changes due to antibiotic use, could play a role. Dr. Jacqueline Casillas, a pediatric hematologist/oncologist, highlights the need to investigate potential prenatal factors contributing to this trend.
Despite the rarity of colorectal cancer in children, Dr. Jeffrey Hyams, a pediatric gastroenterologist, stresses the importance of monitoring symptoms and seeking medical evaluation for persistent abdominal pain, rectal bleeding, anemia, and weight loss. Doctors typically conduct tests like stool testing, blood work, and abdominal X-rays before considering more invasive procedures like a colonoscopy.
Dr. Anton Bilchik, a surgical oncologist, underscores the importance of healthy lifestyle habits from a young age as a preventive measure. While these findings may raise concerns, experts caution against panicking, as colorectal cancer remains extremely rare in children. Additionally, they highlight the significance of early intervention and continued vigilance in maintaining gut health for children.
