TED Health's very own Dr. Shoshana Ungerleider has a new podcast Before We Go.

His doctors were encouraged when testing showed that the cancer was related to a BRCA genetic mutation, which meant that it might respond to new, targeted therapies. But that also meant that Shoshana and her sister were also at risk for developing life-threatening cancers. With the help of renowned experts and some of the professionals who helped her along the way, Shoshana tells her story of love, loss, family, mortality, and the unexpected paths we take to find meaning and purpose in the face of life's greatest challenges.In this episode, Shoshana reflects on the death of her paternal grandmother, Joy Ungerleider, who died of the same cancer Steven now faces. The family learns that Steven's cancer is BRCA-related, and hope rises with the possibility that targeted therapy may offer him many months, if not years, of quality life. But he would first need to endure several months of harsh chemotherapy.
