What an inspiration: 50-year-old Dr. Shauna Burke just became the first woman with stage 4, incurable breast cancer to summit Mount Everest.  It took Burke 12 months of training, and 5 weeks to make it to the top. Burke has already had months of chemotherapy and continued her drug therapy as she made her way up the mountain, where she is conducting research on the effects of exercise and oxygen deprivation on cancer cells. Burke proving to the world with her historic summit, we are all stronger than we think.
