metastatic breast cancer

Metastatic breast cancer occurs when cancer cells from the original tumor in the breast spread to other parts of the body, such as the bones, liver, lungs, or brain. This process happens when cancer cells break away, travel through the blood or lymphatic system, and form new tumors in distant locations. Although it cannot be cured, treatments like targeted therapy, chemotherapy, and hormone therapy can help control the disease, relieve symptoms, and improve quality of life. Ongoing research aims to better understand and develop more effective treatments for metastatic breast cancer.
