By the lovely French paper La Monde. It claims that Lance admitted to doping in '96 to one of his cancer docs and his best friend, Frankie Andreu. But the doc who actually treated Lance disagered that anything like that occured. And we don't know which cancer doc the paper is referring to, because it doesn't say. Not to mention the huge huge ethical issue of disclosing a patients history. He was treated here at MDACC and all employees are rigourously trained every year in regards to patient confidentiality. So, yeah, i'm sceptical (that an American doc would tell a french newspaper about an american patients medical history). Anyway, it would certainly be in the patient history charts (its necessary medical info). Maybe, maybe Lance doped before his cancer, but he certainly didnt' dope afterwords (when he won 7 yellow jerseys).

Facts: He's been tested a zillion times, always clean. Also, he went through hell during chemo and almost died. Would he risk a repeat performance, knowing how close to death he came via chemo drugs?

There was a great (repeat) episode of House on this very topic; big name bike racer, collapses during bike ride, everyone thinks its b/c of doping, but instead he has a rare disease. At issue was the racer's confession of using various drugs (but not EPO) and the issue of medical confidentiatility.
