Together, we can transform the lives of people with metastatic breast cancer.

As a collective of cancer nonprofits, pharmaceutical and biotech industry members and individual patient advocates, the Alliance serves as a national leader in collaborative action to transform and improve the lives of people living with metastatic breast cancer. We leverage the resources and knowledge of our dynamic group of trusted experts to increase awareness and education about the disease, and advocate for policy changes and increased funding for research that holds the potential to extend and enhance life – and ultimately end MBC.

How We Work

Our work to transform and improve the lives of people living with MBC is informed by real-world knowledge and data that identifies existing needs and opportunities.


We envision a world where all people living with metastatic breast cancer receive quality, individualized treatments to live long lives with a good quality of life, and where MBC is no longer a terminal illness.


The mission of the Metastatic Breast Cancer Alliance is to extend life, to enhance quality of life, and to end suffering and death from MBC by:

  • Advancing MBC research
  • Improving access to quality treatments and care
  • Empowering people through increased education and information about the disease, and access to available resources.
