We’ve teamed up with the AFL, Carlton and the Western Bulldogs to launch a campaign called #iknowsome1 that shows Australia just how common bowel cancer is.

#iknowsome1 will be launched at the Carlton v Western Bulldogs game on 10 August 2013.

You can help us simply by posting your photo, and sharing who you know with bowel cancer on Twitter or Instagram using #iknowsome1, or send an SMS with your name to 0487 441 896. For example #iknowsome1 my friend, 41 years.
