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.
The bone is a common site for metastasis. Bone metastasis or bone mets occurs when cancer cells from the primary tumor relocate to the bone. Prostate, breast, and lung cancers are most likely to spread to the bone.However, other cancers are not excluded. Bone metastases do not begin from the bones but move there from the primary tumor site.On the other hand, primary bone cancers are rare cancers where the primary tumor actually starts in the bone.rostate, breast, and lung cancers are most likely to spread to the bone.
