Lance Armstrong was a professional cyclist who won the Tour de France seven times from 1999 to 2005 after recovering from testicular cancer. For years, he denied allegations that he used performance-enhancing drugs. In 2012, the U.S. Anti-Doping Agency concluded that Armstrong had participated in a long-running doping program involving substances such as EPO, testosterone, and blood transfusions, and that members of his team were also involved. As a result, he was stripped of all seven Tour de France titles and banned from professional cycling for life.
