Colorectal Cancer Surges in Young Adults: Tripled Cases in Teenagers and Doubled in Those Aged 20-24 Over the Last Two Decades

Kansas City, Missouri United States of America
Colorectal cancer cases have tripled among teenagers and doubled for young adults aged 20-24 over the last two decades.
Colorectal cancer diagnoses increased by approximately double for individuals in their early twenties, with highest overall rate observed in the early forties.
Study analyzed data from CDC on colorectal cancer incidence in individuals aged 10 to 44 years between 1999 and 2020.
Symptoms of colorectal cancer can be difficult to recognize until more advanced stages of the disease. Common early warning signs include abdominal pain, rectal bleeding, anemia and changes in bathroom habits.
Colorectal Cancer Surges in Young Adults: Tripled Cases in Teenagers and Doubled in Those Aged 20-24 Over the Last Two Decades

In a striking revelation, recent studies have shown that colorectal cancer cases have more than tripled among teenagers and doubled for young adults in the age group of 20 to 24 over the last two decades. These findings challenge the long-held belief that colorectal cancer is primarily a disease of the elderly population. The research, which is scheduled for presentation at Digestive Disease Week (DDW) 2024, analyzed data from the Centers for Disease Control and Prevention (CDC) on colorectal cancer incidence in individuals aged 10 to 44 years between 1999 and 2020. The study was led by Dr. Islam Mohamed, an internal medicine resident physician at the University of Missouri-Kansas City. According to the findings, colorectal cancer diagnoses increased by 500% among children aged 10 to 14, by 333% among teens aged 15 to 19 and by approximately double for individuals in their early twenties. The surge in colorectal cancer cases was observed across all age groups under the age of 45. Late twenties to early thirties experienced a rise of about 70%, late thirties witnessed an increase of 58%, while the highest overall rate was observed in the early forties with a rise of 45%. The study highlights the need for increased awareness, better treatment, and prevention options for younger age groups. The findings also indicate that symptoms of colorectal cancer can be difficult to recognize until more advanced stages of the disease. Common early warning signs include abdominal pain, rectal bleeding, anemia (iron deficiency), and changes in bathroom habits such as diarrhea or constipation. Regular testing can play a crucial role in detecting colorectal cancer at an early stage; however, it is only recommended for individuals older than 45 according to the CDC. Strategies to prevent colorectal cancer include maintaining a diet rich in fiber, avoiding tobacco and alcohol use, and engaging in regular physical exercise. Genetic factors may also contribute to the risk of developing colorectal cancer along with potential risks from the gut microbiome, food additives or certain antibiotics that can disrupt the natural balance of bacteria in the digestive system.
