Lance Armstrong's admission that he used performance-enhancing drugs during his cycling career has made headlines this week.

After years of denials, Armstrong spoke to Oprah Winfrey about his drug use in an interview set to air on Thursday.

Armstrong was a hero to many for surviving testicular cancer and his work raising millions for the Livestrong Foundation, a charity that helps people with cancer.

Edmonton cycling fan Tyla Cooper looked up to Armstrong during her own battle with stage-four Hodgkins Lymphoma.

She shared her feelings about Armstrong's admission with the CBC's Laura Osman.
