What age group is more prone to developing rectal cancer?

The risk of developing colorectal cancer increases with age. People over 50 are at higher risk, with the highest incidence occurring between ages 60 and 75. However, in recent years, there has been a trend toward younger onset, and cases among individuals aged 30 to 40 are gradually increasing. A detailed analysis is as follows:

The risk of colorectal cancer rises significantly after age 50, which is associated with declining intestinal function and the cumulative effects of long-term unhealthy lifestyle habits. As people age, intestinal motility slows down, prolonging the retention time of toxins in the gut and increasing the likelihood of mucosal cell abnormalities. Additionally, this age group often includes more individuals with long-standing habits such as smoking, alcohol consumption, and high-fat diets—factors that collectively elevate cancer risk. Most patients are diagnosed during this stage. Younger individuals should be vigilant about the trend of earlier onset; frequent late-night activities, irregular eating patterns, and insufficient dietary fiber intake commonly impair gut health in young adults.

Regardless of age, everyone should prioritize the prevention of colorectal cancer. Maintain a balanced diet rich in fruits, vegetables, and whole grains, while reducing consumption of processed meats. Engage in regular physical activity to promote healthy bowel motility, and undergo routine colorectal cancer screenings.
