Advanced stage breast cancer is known as metastatic or stage 4 breast cancer. This term means that cancer has spread to other parts of the body.
Back pain is one of the symptoms of metastatic breast cancer. It can appear in later stages of the disease and can result from any of the following:

- the lungs
- the liver
- the bones

As cancer cells rapidly grow out of control, they move into healthy tissues to form new tumors. This spread usually starts with the tissue nearest to where the cancer initially began. When this happens, people may start to experience symptoms in the new area.
When breast cancer spreads to the bones, it can affect:
- the ribs
- the spine
- the pelvis
- bones in the upper arms and thighs
- the skull
A person is likely to feel pain or an ache in the place where cancer has spread, which may include the back.
