"I will no longer address this issue, regardless of the circumstances," Armstrong, a survivor of testicular cancer, said in a statement.
Vowing to work with his cancer foundation, Armstrong, 40, added, "We have a lot of work to do and I'm looking forward to an end to this pointless distraction. I have a responsibility to all those who have stepped forward to devote their time and energy to the cancer cause."
But by backing down in his fight against the USADA, is Armstrong silently admitting he did wrong?
