Moderate alcohol consumption
A diet high in red and processed meats
Low body mass index (BMI)
Genetic factors such as having a family history of colorectal cancer
Chronic inflammatory bowel diseases such as Crohn's disease or ulcerative colitis
Regular physical activity
Correct Answer : C,E,F
A. A diet rich in fruits and vegetables is generally protective against colorectal cancer due to the high fiber content and antioxidants, reducing cancer risk.
B. Moderate alcohol consumption can increase the risk of colorectal cancer, as alcohol has been linked to inflammation and changes in gut microbiota, which may contribute to carcinogenesis.
C. A diet high in red and processed meats has been strongly associated with an increased risk of colorectal cancer due to the presence of carcinogenic substances like nitrates and heterocyclic amines in processed meats.
D. A low body mass index (BMI) is actually protective against cancer in general, as obesity is a significant risk factor for colorectal cancer due to its association with increased inflammation and insulin resistance.
E. Genetic factors such as having a family history of colorectal cancer increase the risk significantly. Inherited syndromes like familial adenomatous polyposis or Lynch syndrome increase the likelihood of developing this cancer.
F. Chronic inflammatory bowel diseases such as Crohn's disease or ulcerative colitis increase the risk of colorectal cancer due to the prolonged inflammation and cellular damage they cause in the colon.
G. Regular physical activity has a protective effect against colorectal cancer by reducing inflammation, improving immune function, and regulating bowel movement.
