A diagnosis of advanced breast cancer means that cancer cells have metastasized (spread) outside of the breast to other parts of the body (such as the bones or other organs) or to the lymph nodes that are not near the breast (such as those above the collarbone). If breast cancer spreads to a different part of the body, it is still regarded as breast cancer. (For example, if breast cancer spreads to the lungs, it is not lung cancer; it is still breast cancer.) Advanced or metastatic breast cancer is referred to as Stage IV breast cancer.
When breast cancer metastasizes or spreads, it usually goes to the bones, lungs and liver. Less commonly, it may also spread to the brain, spinal cord and eye.
What are some of the symptoms?
Metastatic breast cancer can be the initial diagnosis. It may also be a recurrence (return) of breast cancer following initial treatment. (Recurrence will be discussed in more detail later in this section.) Diagnosis of metastatic breast cancer is generally done using some combination of the following tests: bone scan, chest X-ray, CT scan, MRI scan or PET scan. Some symptoms of metastatic breast cancer may include:

Diagnosis of metastatic breast cancer is generally done using some combination of the following tests: bone scan, chest X-ray, CT scan, MRI scan or PET scan. Some symptoms of metastatic breast cancer may include:
- bone pain that does not go away;
- shortness of breath, chest pain, or cough;
- pain or discomfort under the right side of the ribcage that won’t go away;
- lack of appetite;
- unexplained weight loss;
- neurological pain or weakness and headaches;
