SYDNEY - Legendary cricket commentator Richie Benaud revealed Monday he is battling skin cancer and is undergoing radiation therapy, but said he was coping well. The 84-year-old former Australian captain made his illness public at the Nine Network's launch for its Australian summer cricket coverage, saying he was receiving treatment for skin cancers on his forehead and the top of his head. "I'm coping with it very well -- the doctors are pleased," he said. "I'm going along slowly. The cancers need to be treated."
