Padraig Harrington has revealed that he had surgery three weeks ago to remove a skin cancer spot on his forehead. Harrington spoke about the operation after firing a 66 to take the first-round lead at the Wachovia Championship in North Carolina. "I had about a square inch of skin taken out with some roots and all that sort of stuff," said the Dubliner. "It was only a sun spot. I'm told it's like the third form of skin cancer. It was not a melanoma."
