"I never did a lot of sun bathing like some my friends did, because I didn't tan, really," she said. "But of course I played outside for my whole childhood (and) spent afternoons at the swimming pool and did those things that we all did growing up in Texas, and so I was out in the sun a lot."

Laura Bush says she first thought skin cancer was an insect bite

Well, it was a private matter until the press figured it out. Now Laura Bush has joined the list of first ladies who have revealed that they had cancer. Ford eagerly told the public of her breast cancer diagnosis and radical mastectomy in 1974, in an era when breast cancer was still hush-hush. Reagan developed breast cancer in 1987 and made headlines for vocally choosing a mastectomy over a lumpectomy. Thanks to Laura Bush, newspapers, television programs and Internet blogs will now be filled with discussions of the medical significance of skin cancer.

The First Lady was under no obligation to tell anyone anything. She herself is not an elected official. But these days, if you are a public figure, disclosure of just about any illness is fair game.
