Does Cancer improve your looks?

I was thinking about all the media furore following the re-emergence of Princess Catherine at the Trooping of the Colour pageantry that took place in London last Saturday. Naturally all decent people were pleased to see her back after her five month total absence from the spotlight (assuming that it actually *was* her, and I think it was, btw) But the thing that mystifies me is how someone who by her own words claims to have started Chemotherapy in March could look quite so stunning a little under 14 weeks later. Am I alone in finding this a little peculiar? Let’s consider the background to all of this, shall we?
