FAQs
Do I need colon cancer screening?

If a person has an immediate family member diagnosed with colon cancer, then colonoscopy should begin at age 40 or 10 years younger than the age of the family member when they were diagnosed.
Are there different preparations for a colonoscopy, such as ‘low volume prep’?
