Scientific Advisory Board

The Lobular Breast Cancer Alliance (LBCA) is grateful for its esteemed volunteer Scientific Advisory Board

The LBCA Scientific Advisory Board (SAB) is an internationally renowned group of clinicians and scientists with expertise in invasive lobular carcinoma (ILC) research. The SAB members are invaluable to the organization. They are passionately committed to LBCA’s mission, vision, and goals and are a critical resource for LBCA helping us to ensure that all information developed and shared is current, relevant, and accurate. 

SAB members are our ambassadors in the scientific community and help LBCA provide current information about ILC research and clinical trials effectively and in lay terms. Together with LBCA staff and the Board of Directors, SAB members provide strategic guidance and assist with the implementation of LBCA’s planned research advocacy, ILC education, and ILC research grantmaking activities. They assist LBCA in identifying the priority areas for ILC research, and they help ensure that we advance the most important research efforts in these areas.
