00:00 Bowel cancer is a change in the cellular behaviour of the lining of the wall of the large intestine.
00:13 We lose every single one of the cells lining our entire intestine, small and large bowel,
00:21 many metres, every 10 days, not all at once.
00:25 So your bowel motion consists of waste product, bacteria and dead cells.
00:32 For every cell you lose, you get a new one, one for one, all good.
00:38 One cell says, "I ain't going."
00:41 It stays there and it divides and it becomes two and they become four and they become 8,
00:48 16, 32.
00:50 So you have an exponential rate of growth of abnormal cells which at that stage, mushroom-shaped,
00:57 is called a polyp.
00:59 Polyps are benign.
01:00 40% of men, 30% of women, most don't turn to cancer but the cancers all come from the
01:08 polyps.
01:09 If they keep growing, they grow slowly but probably a minimum of 5 years mostly, can
01:18 get them quickly but mostly 5 years before they might turn to a cancer.
01:23 So we have time on our side to find them.
