Can a malignant tumor spread to bones via local metastasis?

Terminology: A tumor can spread to bone locally, but that is not called metastasis. Metastasis means spread to a distant organ either through lymphatics or blood. Tumors can and do metastasize to bones.

Yes: A malignant tumor can spread to other places, including bones. This can happen directly; that is, if a tumor is near a bone, it can grow directly into the bone. It can also happen from a distance, if tumor cells get into the blood stream and travel to the bone. The picture shows the different places cancer goes in the body. I hope that answers your question!
