Lance Armstrong did not get cancer due to PED, he probably used them AFTER he got and recovered from cancer. It has never been proven that he used PED.
However, his major results and all 7 Tour de France victories came AFTER he got cancer. SO he is not a victim of his own habits.
On the contrary, he not only survived cancer, but proceded to make the greatest comeback in cycling, winning the toughest race a record holding 7 times.
Chael does not know what he is talking about.
Fun trivia: In danish "kamp" means "match" or "fight". So Martin Kampmann really lives up to his name.
