Book Description: Primary bone tumours are tumours that start in the bone. In contrast, secondary bone cancer is where the cancer started in another part of the body but has then spread to the bones. The most common types of primary bone tumor are osteosarcoma and Ewing's sarcoma, both of which are most frequently diagnosed in children and young adults. Other less common types of bone cancer include: Chondrosarcoma (a cancer arising in cartilage cells, usually found in adults between ages 50-75, though the less common mesenchymal-chondrosarcoma is more frequent in younger patients), Malignant Fibrous Histiocytoma of bone (MFH), Chondoma (a rare low grade malignancy occurring mostly between ages 30 -70), and other rare tumours. This new book brings together leading research from throughout the world in this important area of research.
