ACE touchscreen question "Have you ever had a screening test for bowel (colorectal) cancer? (Please include tests for blood in the stool/faeces or a colonoscopy or a sigmoidoscopy)"
If the participant activated the Help button they were shown the message:
|Screening tests for bowel or colorectal cancer include:|
- FOBT (faecal occult blood test) - this is when you
are given a set of cards and asked to smear a part
of your stool on three separate occasions onto the
cards and then return the cards to be tested for
- Sigmoidoscopy - a tube is used to examine the lower
bowel. This is usually done in a doctor's office
without pain relief.
- Colonoscopy - a long tube is used the examine the
whole large bowel; you would usually have to drink
a large amount of special liquid to prepare the
bowel, and you would be given a sedative medication
for the procedure.
