Lance Armstrong has confirmed that he will compete in the Tour of Ireland in August when he will promote his cancer charity at a seminar in Dublin following the race. "Unless we act on a global level, cancer will be the leading cause of death by 2010," said Armstrong. "Our goal is to be the catalyst that brings everyone together to fight cancer - from survivors, like me, to world leaders and policymakers who must commit completely to the effort to avoid a public health catastrophe. "The summit provides an invaluable opportunity to stand up for the 28 million cancer survivors worldwide and to create a unified effort to control cancer through new commitments to action." Tour of Ireland director Darach McQuaid said, "The Tour of Ireland could not be more proud than to have Lance Armstrong riding once again on Irish roads in the lead-up to his global cancer summit in Dublin. "The massive, positive public reaction to his comeback to the sport in Australia in January and California in February indicate that, by the time Lance arrives in Ireland next August, the interest levels will be at fever pitch."
