	AllRefer Health - Bone Tumors (Tumor - Bone)
		A bone tumor is an abnormal growth of cells within the bone that may be benign or malignant (cancerous).
		Malignant bone tumors occur as a primary bone tumor or as metastasis (cancer spread from another area of the body).
		Bone cancer was once prevalent among individuals who painted radium on watch faces (to produce glow-in-the-dark dials), a practice that was abandoned in the middle of the 20th century.

	Musculo-Skeletal Tumor Orthopaedic Practice (MUSTOP)
		Tumors arising from small tubular bones such as the ulna, metatarsal, or metacarpal are usually centrally located and produce symmetric expansion of the bone.
		Histologically, the tumor consists of a cartilaginous tumor of low-grade malignancy and a noncartilaginous high-grade malignant component.
		In the bone, the lesion is lytic and stippled with calcifications, cortical destruction, and soft tissue extension.

	Canine Osteosarcoma
		Bone tumors are tender so it is usually clear what part of the limb should be radiographed.
		Sometimes a bone tumor is surrounded by an area of bone inflammation and it may be difficult to get a diagnostic sample and several samples must be taken.
		The squamous cell carcinoma tends not to arise in the same bone areas as the osteosarcoma; it tends to arise in the jaw bones or in the toe bones.
