How Does Breast Cancer Spread?
Cancer cells may spread from the breast to other parts of the body through the bloodstream or the lymphatic system. This process is also known as metastasis. They may also invade surrounding tissues in the ribs or chest wall. When these cells penetrate the lymphatic system, they typically first reach nearby lymph nodes. This would be still in the early stage. Treatment options can vary, depending on the affected areas of metastasis. [2]
