When breast cancer spreads to the spine, it's known as bone metastasis. And unfortunately yes, breast cancer that has spread to the bones may spread to other areas such as the brain as well. This happens when cancer cells break away from the primary tumor and travel through the circulatory system. The most common areas for breast cancer to spread are the bones, lung, liver, and brain.
Cancer that begins in an organ, such as the lungs, breast, or prostate, and then spreads to bone is called metastatic bone disease (MBD). More than 1.2 million new cancer cases are diagnosed each year. Approximately 50% of these tumors can spread (metastasize) to the skeleton.his type of damage is most common in cancers that have spread to bone from the lung, thyroid, kidney, and colon. Alternatively, new bone can form in response to the cancer spread. This new bone, called osteoblastic, grows abnormally and causes the bone to be weak and deformed.
