Colonoscopy ! (Gold Standard)

| -CEA shouldn't normally be secreted by us
an embryo would make this substance...??

An example of a DNA diagnostic test for colon cancer is what ?
Cologuard

True
52
True or False:
- Cologuard is intended for people who are not high risk for colon cancer

True
53
For individuals at average risk for colon cancer, they should have one of the following procedures starting at age 50 for prevention and screening ?

- Double-contrast barium enema (every 5yrs)*
* if positive --> do colonoscopy
- If polyps removed, colonoscopy moved up to every 5yrs
54
If your at increased or high risk for colon cancer, prevention & screening usually start between what ages ?

Every 5yrs
56
If there is a family hx of colon cancer, what age should screening begin at ?
Begin at 40 or 10yrs before the age of the youngest family member diagnosis
