Singing legend Cher is brushing off media rumors that a cancer diagnosis forced her to pull out of her Las Vegas shows earlier this month, and says she is very fit and well. The icon canceled two performances at the Colosseum at Caesar's Palace, her final dates of the year, in early October.Her publicist, Liz Rosenberg, quickly denied reports that a serious ailment had stricken the famed star, which only prompted rumors she was privately dealing with cancer. But Cher has laughed off the claims as another bizarre report by gossipmongers, insisting she was unable to sing due to a sore throat. She says, "My health is great but there's a wind thing that blows there (in Las Vegas) at different months and I have an allergy to it. If I had cancer everyone would know it. I wouldn't tell them, but somebody would. When you have those kind of things happen if you're famous you can't keep them a secret. "(The reports) don't make me angry. People have been saying the weirdest things since I was a teenager."
