Kate's cancer diagnosis sparks a wave of sympathy

Warm wishes flooded in from around the world after Catherine, Princess of Wales, revealed that she was being treated for cancer.

The wife of Britain's heir to the throne, William, had been the topic of fevered speculation over her condition, fueled by silence from the palace and a botched family snap that the princess later admitted editing.

But her bombshell video announcement appeared to have brought a halt to the gossip and evoked expressions of sympathy from family near and far, world leaders, and public figures.
