According to the three-paragraph biography on Lance Armstrong.com, Armstrong managed to survive cancer and return to be a seven-time Tour De France winner, Fox News reports. The website also said that Armstrong's experience as a cancer survivor motivated him to show the same drive in his fight against cancer that made him excel in the sport. Armstrong, during last week's interview with Winfrey, said he finally cracked after he saw his son defending him against allegations from anti-doping authorities.
