A bone tumor is an abnormal growth of tissue in bone. Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. There may be a lump, pain, or neurological signs from pressure. A bone tumor might present with a pathologic fracture. Other symptoms may include fatigue, fever, weight loss, anemia and nausea. Sometimes there are no symptoms and the tumor is found when investigating another problem.
Diagnosis is generally by X-ray and other radiological tests such as CT scan, MRI, PET scan and bone scintigraphy. Blood tests might include a complete blood count, inflammatory markers, serum electrophoresis, PSA, kidney function and liver function. Urine may be tested for Bence Jones protein. For confirmation of diagnosis, a biopsy for histological evaluation might be required.
The most common bone tumor is a non-ossifying fibroma. Average five-year survival in the United States after being diagnosed with bone and joint cancer is 68%. The earliest known bone tumor was an osteosarcoma in a foot bone discovered in South Africa, between 1.6 and 1.8 million years ago.
How this connects to Orthopaedics
Cancer biology involves abnormal clonal growth, tissue invasion and interactions with immune, stromal and vascular components. Tumor type, grade, stage and molecular findings answer different questions; diagnostic and treatment decisions require tissue-specific evidence and multidisciplinary clinical assessment.

What the underlying subject studies
Orthopaedics examines bones, joints, muscles, tendons and related nerves and vessels. Normal biomechanics helps explain how force, alignment, tissue healing and load distribution influence movement and injury.
How mechanisms and evidence connect
Bone and soft-tissue pathology can alter structural stability, circulation or neurological function. Mechanisms, injury pattern and tissue condition matter alongside any single radiographic appearance.
How to develop a sound explanation
Use a labeled region map to identify articulating bones, muscle groups, nerves and movement. Clinical imaging and examination are required to distinguish disorders and plan management.
