Summers, best known as the host of Nickelodeon's "Double Dare" and the Food Network's "Unwrapped" (which doesn't even touch on the numerous shows on which he's served as producer), told listeners that he was diagnosed with chronic lymphocytic leukemia five years ago. He was in chemo for two years, yet still went about his daily business, not revealing his diagnosis. During this time, Summers also was involved in a taxi crash. Summers acknowledged that it wasn't an easy time, calling it "hell."
