Welcome to the METAvivor Blog. We are excited about providing an opportunity to share and discuss issues that affect people with metastatic breast cancer in more depth. We plan to invite posts from those living with MBC, as well as from clinicians, researchers, activists, authors, and breast cancer bloggers who do not have mets themselves, but who support those who do by being ‘fearless friends,’ or who are involved in careers to extend life and/or improve quality of life for the MBC community. Far too often, individuals with MBC experience isolation, especially from the so-called breast cancer awareness culture at large. We want to change that. The only way to make real progress, to advance real awareness, is for all of us to work together.
