Mary Murphy Announces Cancer-Free DiagnosisMary Murphy is letting her trademark enthusiasm show, and for good reason: The 'So You Think You Can Dance' judge announced to Life & Style that she has overcome thyroid cancer.

The 52-year-old dancer and choreographer discovered she had the disease three years ago, when doctors found a tumor on her thyroid, but only had the surgery to remove the tumor in December 2010.

"They told me that the tumor had to come out and there's a chance I might not be able to talk again. Outside of the word 'cancer,' I really couldn't imagine my life without hearing myself laugh."

"I definitely feel like there's an angel on my shoulder," says Murphy. "I feel like somebody's looking out for me."
