Over the past 20 years, colorectal cancer has increasingly affected younger people in the United States. Research indicates a significant rise in the incidence rate of colorectal cancer among those under 45, with a fivefold increase among children aged 10 to 14. This notable trend has garnered widespread attention, prompting recommendations to further lower the current screening age of 45.
Experts also urge the public to enhance their awareness of colorectal cancer and to manage modifiable risk factors, such as poor diet and unhealthy lifestyle habits. Ages 10 to 14: increased by 500 percent Ages 15 to 19: increased by 333 percent Ages 20 to 24: increased by 185 percent Ages 25 to 29: increased by 68 percent Ages 30 to 34: increased by 71 percent Ages 35 to 39: increased by 58 percent Ages 40 to 44: increased by 45 percent This study primarily studied people under 45, as they are not included in the current screening guidelines. This oversight increases the risk of missing early detection and treatment opportunities for colorectal cancer, particularly among children and adolescents.
Mohamed said in the press release that regardless of age, the possibility of colorectal cancer should not be ruled out if related symptoms are present. “It’s important that the public is aware of signs and symptoms of colorectal cancer,” he added. Patients with early-onset colorectal cancer may experience changes in bowel habits, abdominal pain, or rectal bleeding.
Mohamed noted that if these symptoms occur, taking them seriously and seeking timely evaluation is essential. According to the American Cancer Society, while there is no definitive method to prevent colorectal cancer, screening can detect abnormal cells before they progress to cancer. Additionally, managing modifiable risk factors may help reduce the risk of developing cancer.
Marshall also mentioned that young people in modern environments are exposed to more colorectal cancer risk factors, including poor dietary habits (such as high consumption of processed foods), obesity, and frequent use of products containing microplastics. The American Cancer Society identifies obesity, high consumption of red and processed meats, smoking, and alcohol use as modifiable risk factors for colorectal cancer. In contrast, genetic factors, which are nonmodifiable, account for only about 5 percent of colorectal cancer cases.
Yang pointed out that microplastics may release carcinogenic substances, increase inflammation, induce oxidative damage in the body, and even lead to DNA mutations. Therefore, minimizing the use of products containing microplastics and nanoplastics is advisable to reduce the risk factors for colorectal cancer and other diseases..
