Metastatic breast cancer is the most advanced stage of breast cancer (also known as stage IV). It means the cancer has spread beyond the breast to other distant parts of the body.

Metastatic breast cancer can’t be cured and is more difficult to treat than early-stage breast cancer, yet there are many treatment options for metastatic breast cancer available. These options include chemotherapy, hormonal therapy, and targeted therapy, according to Amy Tiersten, MD, Hematologist-Oncologist at the Mount Sinai Hospital in New York City.
