> In late April 2014, Bain announced he had a precancerous mass in his colon, the first indications of bowel cancer, a condition with which two of his grandparents had also been diagnosed. (wikipedia)

It's good to promote diagnosis, but let's also put this in perspective: he had family history of this kind of cancer. This kind of changes everything when it comes to your personal risk, just like your grand parents having Alzheimer indicate a major risk that you will get it as you age as well.

This is why (good?) doctors also ask for conditions running in families.
