Our Mission

The Metastatic Breast Cancer Network (MBCN), a volunteer, patient-led advocacy organization, seeks to address the unique needs and concerns of women and men who are living with metastatic or Stage IV breast cancer.

Not just being alive... LIVING!

Pragmatism. Realism. Optimism.

On March 8, 2018, MBCN’s Shirley Mertz was among the speakers at Susan G Komen Chicago’s first ever Metastatic Breast Cancer Conference. Shirley shares her own story, offers tips for getting the best care and showcases the Metastatic Breast Cancer Trial Search engine. Bonus: Shirley also touches on the Metastatic Breast Cancer Alliance’s forthcoming Connect registry. It’s a very informative 15 minutes!

Katherine O’Brien

As president of the Metastatic Breast Cancer Network, I share with great sadness that Katherine O’Brien, a MBCN Board Member since 2013, and its Secretary and Public Relations and Social Media Chair, passed away on Saturday, June 19. As a full-time patient advocate, Katherine was a dear friend to many in the metastatic breast cancer community. She used her amazing writing skills and empathy to share stories of patients living with the disease on MBCN’s website as well as important facts and information about the disease and its treatments. As a patient advocate, Katherine was followed on Twitter by many who appreciated her wit and learned from her insights.

In addition to her advocacy with MBCN, Katherine shared her skills with Living Beyond Breast Cancer, SHARE Cancer Support, Susan G. Komen, and the Metastatic Breast Cancer Alliance, of which MBCN is a founding member. Most recently, Katherine developed a well-received campaign for the MBC Alliance (MBCAlliance.org) called “Here All Year,” which monthly explores a topic around metastatic breast cancer. Katherine was a graduate of Project LEAD, and she regularly attended ASCO and SABCS conferences.

Katherine will be missed, but never forgotten by all of us who knew her and called her friend.
