What does it mean to receive an mBC diagnosis?

While early-stage breast cancer itself is a life-changing diagnosis, there is still hope for possibility of remission and full recovery. Despite improvements made with earlier detection and treatment, there is currently no cure for mBC.2 Only about 30% of women are still alive five years after receiving their mBC diagnosis.1
