'Testing twice for bowel cancer increases detection and could be key to saving lives'

Now, here’s an interesting one. The detection of bowel cancer is increased to almost 100% by testing for it twice, rather than just once.

The simple faecal immunochemical test, or FIT, is used to detect blood in bowel movements that isn’t visible to the eye but may indicate the presence of bowel cancer.

Researchers at Edinburgh University improved their success rate simply by doing the test for a second time.
