Dying to live. Andie speaks to Kristin Hallenga from CoppaFeel.

Kris Hallenga was told she had terminal cancer at 23 - after being told by a doctor a lump in her breast was hormonal and nothing to worry about. She's dedicated her life to warning young women about the warning signs of breast cancer, by starting the charity CoppaFeel. Andie spoke to Kris ahead of a BBC Three documentary about her, Dying To Live.
