To where does breast cancer spread?
Breast cancer that has spread from where it began in the breast (generally either the ducts or lobules) to other tissues of the body is referred to as invasive breast cancer, or metastatic breast cancer. The most common sites of spread of metastatic breast cancer are the bone, the lungs, the liver, and the brain. Cancer that is then detected in one of these organs involved is referred to as breast cancer that has metastasized to the particular organ. It is not referred to as cancer of that organ.
