As she had to cancel a major tour, it was a little difficult to not give a reason. And I agree with Sue, it would have leaked out soon enough, so best be up front with it I think.
The part I've found the most ridiculous is the way that every news show has run a piece on how 'the media' are hounding the poor girl, and shouldn't they just keep away? Um people, aren't you the media? And the way they illustrate the story and how shameful it is: "other stations show images like these" and then procede to show the same images!
I don't know about the fund-raising side, but what's really great is that screening centres reported massive increases in enquiries and bookings in the days after the news was broken. Until there is a cure, the best hope is still early detection. It certainly brought it home to me again that it isn't only 'older' women who have to worry (I'm a couple of years younger than our Kyles). Coincidentally, I had already made a mental note to have a check-up earlier that day when I'd seen a 17-year-old girl with breast cancer (on Dr Phil, which I hardly ever watch, so I took that as a further sign).
