Definitely a brilliant idea, think everyone who can should do it. My mum was diagnosed with bowel cancer just over a year ago, she suffered no symptoms and it was just very lucky she was seeing the GP anyway (piles ) and the GP picked it up. Because they got it early she avoided all the chemo etc and has had a relatively easy recovery, but still isn't back to herself after a year so god knows what she'd be like if it had been caught later.
Far too easy a thing to miss, this test is vital.
