What is a primary bone tumor?
Introduction. Primary bone cancer (PBC) is a rare malignant tumor of the bone, originating from primitive mesenchymal cells. It accounts for around 0.2% of all malignancies worldwide and is idiopathic in most cases. There are multiple subtypes, with osteosarcoma, chondrosarcoma, and Ewing sarcoma, the most common.

Primary bone cancer – This means that the cancer starts in the bone. fact sheet. Secondary bone cancer – This means the cancer started in another part of the body but has now spread (metastasised) to the bone. It may also be called metastatic bone cancer, bone metastases or bone mets.
What is the most common primary bone tumor?
Osteosarcoma. Osteosarcoma (also called osteogenic sarcoma) is the most common primary bone cancer. It starts in an early form of bone cells. It most often occurs in young people between the ages of 10 and 30, but about 1 in 10 osteosarcomas develop in people older than 60.
How are primary bone Tumours classified?
Definition. Bone tumors can be classified as primary or metastatic. Primary tumors are divided into benign and malignant. Benign lesions include developmental abnormalities such as fibrous dysplasia and osteochondroma, categorized as pseudotumors.
What are secondary bone tumors?
Secondary bone cancer is when a cancer that started somewhere else in the body has spread to the bones. to another part of the body, where they can form a new tumour. This is called a secondary cancer. Secondary cancers are also called metastases (pronounced met-ass-ta-sees).

What causes bone tumors?
The causes of bone tumors aren’t known. A few possible causes are genetics, radiation treatment, and injuries to the bones. Osteosarcoma has been linked to radiation treatment (particularly high doses of radiation) and other anticancer drugs, especially in children. However, a direct cause hasn’t been identified.
How many types of bone tumors are there?
Malignant, or cancerous types of bone tumors come in two types, primary and secondary. Primary tumors start in the bone, itself. On the other hand, secondary tumors start somewhere else and spread (or metastasize). Primary tumors usually happen in children, though some adults get them, too.
What is the best treatment for bone metastases?
The best treatment for bone metastasis is the treatment of the primary cancer. Therapies may include chemotherapy, hormone therapy, radiation therapy, immunotherapy, or treatment with monoclonal antibodies. Pain is often treated with narcotics and other pain medications, such as non-steroidal anti-inflammatory agents.
