NEW YORK -- Lance Armstrong says he is not returning to professional cycling because of any unfinished business from his previous exit.In an exclusive interview with ESPN.com, the seven-time Tour de France winner said he considered his retirement on top to have been ideal and maintained his comeback is not an attempt to address questions about whether he raced clean. While he clearly relishes the thought of competition again, Armstrong said he will judge his success only partly based on his cycling results and mostly by how well it meshes with a campaign to marshall more resources for a global war on cancer.
