You are a family physician seeing a 47-year-old woman and her husband
of the same age. They are concerned because a friend recently found out
that she had bowel cancer and has urged them both to undergo screening
with fecal occult blood tests (FOBTs) because, she says, prevention is
much better than the cure she is now undergoing. Both your patients
have no family history of bowel cancer and no change in bowel habit.
They ask whether you agree that they should be screened.
