A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant).[1][4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate.[1] There may be a lump, pain, or neurological signs from pressure.[1] A bone tumor might present with a pathologic fracture.[1] Other symptoms may include fatigue, fever, weight loss, anemia and nausea.[2][3] Sometimes there are no symptoms and the tumour is found when investigating another problem.[2][3]
Diagnosis is generally by X-ray and other radiological tests such as CT scan, MRI, PET scan and bone scintigraphy.[1] Blood tests might include a complete blood count, inflammatory markers, serum electrophoresis, PSA, kidney function and liver function.[1] Urine may be tested for Bence Jones protein.[1] For confirmation of diagnosis, a biopsy for histological evaluation might be required.[1]
The most common bone tumor is a non-ossifying fibroma.[4] Average five-year survival in the United States after being diagnosed with bone and joint cancer is 67%.[5] 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.[6]
