I’m starting to be convinced it’s due to 100 different reasons, but each of those reasons is due to people doing things the extreme.

Eating too much processed food? There are studies showing an increase in risk. Sit too much every day? Ditto. Long distance running? When taken to the extreme it increases colon cancer risk (recent research)

A measured, balanced lifestyle regarding your activity and habits is the best thing you can do to put yourself in a good position to avoid diseases or health complications.
