The purpose of this research study is to test a new way to deliver oncology and palliative care for patients with metastatic breast cancer. * The goal of this study is to test a model where oncology and palliative care work together to care for participants with metastatic breast cancer who were recently admitted to the hospital or have new or worsening cancer involving their brain or the fluid around the brain or spinal cord. * The investigators are studying whether participants who receive care from both teams have better communication about their care and improved quality of life and mood compared to those receiving care from only their oncologists. The purpose of this randomized clinical trial is to conduct a randomized trial testing the impact of the collaborative palliative and oncology care model or standard oncology care models among patients with poor prognosis metastatic breast cancer. Participants assigned to the intervention arm will participate in a series of structured palliative care visits, following tailored clinical practice guidelines previously developed for patients with metastatic breast cancer.
