"The term bone tumour or bone lesion can be applied to a bewildering number of entities including primary and metastatic neoplasms as well as a variety of metabolic, developmental, lymphoid, reactive and tumour-like lesions that affect bone1-4. Hence, there are a wide variety of radiological appearances."
"A systematic approach taking into account location, patient demographic and imaging appearances can often substantially narrow the differential. This is especially important if the mass is a benign "don't touch" lesion that could be safely ignored or observed."

"More indolent processes may be managed with curettage combined with local adjuvants such as bone cement (polymethyl methacrylate), bone graft, phenol or liquid nitrogen."
"This is an overview article; for more information please refer to the articles on each subtype described below."
"There are numerous individual tumour entities which come under the umbrella term "bone tumour". For a formal and updated classification of bone tumours, see WHO classification of tumours of bone. They can broadly be divided into:"
"In general, for more aggressive lesions, surgery, chemotherapy, and radiotherapy are offered according to the stage, resectability, operability, and functional status. Targeted treatments depend on molecular testing."
