Bone tumours.
Understand. Preserve. Restore.

From a concerning X-ray finding to expert histopathology, multidisciplinary planning and reconstruction. A patient pathway, real clinical imaging and an evidence-based clinician layer.

What brought you here?

You do not need to know the pathology yet. Choose the decision you need to make next.

The diagnostic sequence

Step 1Baseline imaging

Radiographs are often first; CT and MRI are added according to the lesion.

Step 2Staging

Local extent, the chest and other areas are assessed according to the suspected diagnosis.

Step 3Planned biopsy

The biopsy track is placed within the future resection rather than selected in isolation.

Step 4Resection and reconstruction

Oncological removal and restoration of bone or joint function are planned together.

Bone Tumour and Orthopaedic Oncology Centre

Not every bone lesion is cancer. This centre combines patient pathways, clinician resources, source-confirmed clinical cases and an MRI/CT atlas. We explain how a specialist team connects imaging, pathology, treatment and function.

When not to delay assessment

Persistent or night bone pain, swelling, pain after minor loading, possible pathological fracture or progressive loss of function should be investigated. A normal X-ray does not always exclude serious disease. Seek urgent care if you cannot bear weight or a fracture is suspected.

Key point: when a primary malignant bone tumour is suspected, the biopsy must be planned after adequate imaging with the specialist team that can provide definitive treatment. Unplanned surgery can compromise limb-sparing options.

Real documented cases

Clinical media are de-identified. Where pathology is not supplied, the imaging atlas describes anatomy without asserting a diagnosis.

Common questions

Does every bone lesion require surgery?

No. Some benign findings need surveillance only; suspicious or aggressive lesions may require specialist imaging and planned biopsy.

Can a biopsy be performed before specialist review?

Suspected bone sarcoma should first undergo appropriate MRI and specialist biopsy tract planning.

Is limb-sparing surgery an option?

Often, yes. Feasibility depends on pathology, extent, achievable margins and safe functional reconstruction.

Dedicated clinician staging: AJCC 8

TNM, grade, pelvic/spinal exceptions and why not every bone lesion receives a malignant bone sarcoma stage.

For clinicians · AJCC 8

Primary bone tumour staging

Four components describe the anatomical extent and histological grade, but a stage group cannot be inferred from size alone. Confirm the diagnosis and the applicable anatomical system first.

TPrimary size and local extension
NRegional nodes
MDistant metastasis
GHistological grade

Important: pelvic and spinal primary bone tumours have specific T categories without the usual prognostic stage groups IA-IVB. Giant cell tumour and benign lesions do not receive a malignant bone sarcoma AJCC stage.
