Key Points:

Colorectal cancer, traditionally seen in older adults, is increasingly diagnosed in younger people under 50, with cases reported even in patients in their teens and early 20s, reflecting a global trend.
About 80% of early onset colorectal cancer cases are not linked to genetic factors; experts attribute the rise primarily to environmental and lifestyle factors such as diets high in red meat and ultra-processed foods, low fiber intake, and lack of exercise.
Preventative measures include regular exercise, avoiding smoking, moderating alcohol consumption, and eating a diet rich in fruits, vegetables, and fiber, while obesity is also recognized as a risk factor.
The U.S. Preventive Services Task Force recommends colorectal cancer screening starting at age 45
