(Mike Krumboltz) When Emily Helck began treatment for breast cancer, she decided to document each day with photos. At the end of a year, Helck put the images together in an emotional time-lapse video.

The video, which starts in September 2012, and ends a year later, manages to be both heartbreaking and life-affirming. The inevitable physical changes that come with cancer treatment appear early. But through it all, Helck's bravery and openness remain a constant.
