Metastatic breast cancer (MBC) is cancer that has spread to other parts of the body than the breast, such as the bones, liver, lung or brain. This is categorised as an advanced stage of cancer. Metastatic breast cancer can also be called Stage IV or advanced cancer.
For young women diagnosed with MBC it is important to know that while it is not curable, it is highly treatable. In fact, younger women with de novo MBC (stage IV disease upon diagnosis) were found to have better outcomes compared to their older counterparts.
