Learning you have breast cancer can feel scary and overwhelming. But you’re not alone. 1 in 8 women in the US will be diagnosed in their lifetime. Of those diagnosed, about 1 in 3 will become metastatic (meaning the cancer’s spread to other parts of the body) – so let’s talk about it.If you or a loved one are part of this stat, take a deep breath, then press play to learn:

  • What exactly is metastatic breast cancer (or mBC)?

  • How common is mBC?

  • Is all mBC the same?

  • What are cancer biomarkers?

  • What is Human Epidermal Growth Factor Receptor 2 (aka HER2) and how does it make your disease unique?

  • How has understanding of HER2 evolved over time?

If this info helps you, pass it on — someone else might need it too.
