Metastatic breast cancer, also known as stage IV breast cancer, is an advanced stage of breast cancer where cancer cells have spread beyond the breast and nearby lymph nodes to other parts of the body. In metastatic breast cancer, cancer cells can travel through the bloodstream or lymphatic system and form new tumors in distant organs. The most common sites of metastasis include the bones, liver, lungs, and brain.
It's important for individuals with metastatic breast cancer to work closely with their healthcare team to discuss treatment options, manage symptoms, and address emotional and supportive care needs. Ongoing research and clinical trials continue to explore new therapies and approaches to improve outcomes for individuals with metastatic breast cancer.
