How to choose Colorectal Cancer screening method?

Screening options for general-risk groups (ie, no family history or medical history of polyps, colon cancer, or inflammatory bowel disease, and no history of abdominal radiotherapy or prostate cancer radiotherapy in children) include colonoscopy, virtual colonoscopy, and stool examination.

 

Risk Factors of Colon cancer

Colonoscopy is the gold standard for screening colorectal cancer, and it is recommended to be done every ten years.

A colonoscopy doctor can view the inside of the colon and remove polyps or abnormal tissue for further detection.

Another less invasive option is virtual colonoscopy, or colon CT scan, which is recommended every five years.

However, if polyps are detected, colonoscopy is still required.

 

Other options include stool DNA testing, which should be done every three years. It is recommended to have a stool blood test once a year.
