Metastatic breast cancer is the most advanced stage of breast cancer—stage 4—and occurs when the cancer has spread to other parts of the body, such as the lungs, liver, brain and/or bones. Most commonly, metastatic breast cancer develops after treatment for early-stage breast cancer, as microscopic tumor cells can remain in the body and metastasize even after the original tumor has been removed.

Metastatic breast cancer symptoms can vary based on where in the body the cancer has spread:

  • Lungs – Dry cough, hoarse voice and difficulty breathing
  • Liver – Jaundice, pain or swelling in the belly, change in bowel habits, loss of appetite and itchy skin or rash
  • Brain – Blurred vision, dizziness, headaches, loss of balance, frequent nausea or vomiting, confusion and memory problems
  • Bones – Swelling, bone fractures and back, neck, bone or joint pain

Other common symptoms of metastatic breast cancer include fatigue, unexplained weight loss and difficulty urinating. Individuals experiencing these symptoms for two weeks or longer should speak with a doctor. While these symptoms may be related to side effects of treatment or another condition, a doctor can perform a series of tests to determine the cause.
