Metastatic breast cancer means that the cancer has spread to other parts of the body like the lungs, liver, brain, and bones. It's the final and most deadly stage of breast cancer, and one that is being extensively studied.
Early stage breast cancer usually has a clear treatment plan, while metastatic breast cancer is much more complex.
Donations to the Susan G. Komen Foundation support research into metastatic breast cancer treatments, including raising the comfort and quality of life of patients.
