What is Metastatic Breast Cancer?

Metastatic breast cancer, or stage IV (4) breast cancer, is cancer that has spread to a different part of the body.

If you have had been treated for breast cancer in the past and develop a new growth or cancer in a different part of the body, your doctor may perform tests to confirm if the cancer has recurred. The most common sites for breast cancer to spread to are the bones, lungs, liver, lymph nodes, adrenal gland and brain.
