Brittany Maynard, advocate for the terminally ill, has ended her life 'with dignity'

A young American woman with brain cancer, who became an advocate for terminally ill patients who want to end their own lives, has died using Oregon's doctor-assisted suicide law. 

Brittany Maynard, 29, triggered shock and controversy over the right to die when a video of her making her suicide promise went viral in October and was seen by millions of web users.
