Bone metastasis

<p>Bone metastasis, or osseous metastatic disease, is a category of <a href="/facts/Cancer/PVW6n1D0">cancer</a> <a href="/facts/Metastases/4dadbm6z">metastases</a> that result from <a href="/facts/Primary_tumor/bRey029u">primary tumor</a> invasions into <a href="/facts/Bone/kwJaR6IQ">bones</a>. Bone-originating primary tumors such as <a href="/facts/Osteosarcoma/FnlFbprC">osteosarcoma</a>, <a href="/facts/Chondrosarcoma/k4Wa0FUa">chondrosarcoma</a>, and <a href="/facts/Ewing_sarcoma/xT80aCbS">Ewing sarcoma</a> are rare; the most common bone tumor is a metastasis. Bone metastases can be classified as <a href="/facts/Osteolytic_lesion/8sg61McY">osteolytic</a>, osteoblastic, or both. Unlike <a href="/facts/Hematological_malignancy/tzyyShka">hematologic malignancies</a> which originate in the blood and form non-solid tumors, bone metastases generally arise from <a href="/facts/Epithelium/ecKHcHC3">epithelial</a> tumors and form a solid mass inside the bone. Primary breast cancer patients are particularly vulnerable to develop bone metastases.  Bone metastases, especially in a state of advanced disease, can cause severe pain, characterized by a dull, constant ache with periodic spikes of incident pain.
