Yup he cheated. He's a giant piece of you know what because of that, the fact he became a false hero for cancer patients that couldn't be at his level of rich/celebrity and survive makes it worse. The fact that kids looked up to him all these years and really showed them that you really can't push to be the best, you just have to cheat for it makes it over the top.
It's really sad I've had to see my best friend in his last stages look up to lance and thought of him as a winner, a fighter, and a hero. Well he never made it to see how lance turned out.
