Wow, this sucks. If we didn't live in a world filled with so much greed and corruption, we might have found a cure for cancer 20 years ago.
I'm the same age as Princess Kate, so it kind of puts things in perspective. Well, other than the fact that she's rich, famous, and attractive (none of which I am, and likely never will be), she's got access to some of the finest medical care on the planet... it's all well and good if she's recuperating from malaria or a horrific skiing accident which might permanently cripple or even kill Joe Q Average. But even the best and brightest physicians and scientists aren't able to reliably conquer cancer.
Hope she pulls through for her kids' sake.
