大腸癌的預防飲食以高纖、低脂、多蔬果為原則，規律運動能促進腸道蠕動，減少糞便與腸黏膜接觸時間，是公認有效的預防措施。B 錯，低劑量阿斯匹靈對特定高風險族群可能有保護作用；C 錯，無證據支持維生素 C 能預防癌症；D 錯，陽光曝曬與皮膚癌相關。
Increasing dietary fiber and engaging in regular physical activity are evidence-based strategies to reduce colorectal cancer risk by promoting bowel motility and reducing systemic inflammation. Other options such as limiting sun exposure target skin cancer, while there is insufficient evidence to support vitamin C supplements or avoiding low-dose aspirin for this specific prevention goal.
