Key facts

Bone cancer at a glance.

The essentials, in plain English. What primary bone cancer is, who it affects, and how it is treated in the UK today.

  • What it is

    A primary malignant tumour arising from bone or cartilage. Osteosarcoma, Ewing sarcoma, chondrosarcoma and chordoma are the main types.

  • How common

    Rare. Fewer than 600 new primary bone sarcomas each year in the UK. Bone metastasis from other cancers is far more common.

  • Who it affects

    Osteosarcoma and Ewing sarcoma peak in adolescents and young adults. Chondrosarcoma and chordoma are more typical in middle and later life.

  • Red flag

    Persistent, unexplained bone pain, especially night pain, with or without a lump or an unexpected fracture. Always warrants imaging.

  • Care pathway

    All suspected cases go through one of the 15 UK supraregional bone sarcoma centres. Biopsy is planned at the treating centre.

  • Foundation therapy

    Coordinated MDT care: chemotherapy where indicated, limb-salvage surgery, and radiotherapy including proton beam therapy for selected tumours.

Why this guide matters

A specialist pathway, from the very first appointment.

Bone cancer is uncommon, and its symptoms can look like many benign problems. Three principles shape UK sarcoma care and everything else on this page.

  • Early imaging changes outcomes

    Persistent bone pain, especially night pain, or an unexplained bone lump needs an X-ray, and often an MRI, without delay.

  • Biopsy belongs at the sarcoma centre

    A biopsy tract that is not planned by the surgical team can compromise limb-salvage surgery. Refer first, then biopsy.

  • Treatment is a coordinated team effort

    Chemotherapy, complex orthopaedic surgery, proton beam therapy and long-term rehabilitation are all delivered through one MDT.

How the diagnosis is made

From a suspicious X-ray to a confirmed sarcoma plan.

The steps a UK sarcoma team will normally follow, in order, so you know what to expect and why each investigation matters.

  1. 01

    Imaging

    Urgent plain radiograph

    The first-line test for unexplained bone pain or a suspected mass. Suspicious features trigger same-day onward referral.

  2. 02

    Imaging

    MRI of the whole affected bone

    Maps tumour extent, marrow involvement and skip lesions. Essential before any biopsy or surgical planning.

  3. 03

    Imaging

    Staging imaging

    CT chest for lung metastases, whole-body bone scan or PET-CT to look for distant disease and multifocal involvement.

  4. 04

    Diagnosis

    Core needle biopsy at a sarcoma centre

    Biopsy is planned and taken at the treating sarcoma centre. A poorly placed biopsy can compromise later limb-salvage surgery.

  5. 05

    Diagnosis

    Molecular and immunohistochemistry

    EWSR1 fusions in Ewing sarcoma, MDM2 amplification in low-grade osteosarcoma variants, H3K36M and H3G34W in cartilage and giant cell tumours.

  6. 06

    Diagnosis

    Bloods and prognostic markers

    Full blood count, renal and liver function, calcium, ALP and LDH. LDH and ALP carry prognostic weight in Ewing sarcoma and osteosarcoma.

  7. 07

    Planning

    Genetic and syndrome assessment

    Li-Fraumeni (TP53), Rothmund-Thomson, hereditary retinoblastoma (RB1) and Paget-related SQSTM1 mutations may be relevant. Genetics review where indicated.

Typical timeline: from urgent referral to an MDT plan within two to three weeks at a UK sarcoma centre.

Symptoms

What bone cancer can look and feel like.

Symptoms often overlap with sports injuries and growing pains, which is why the pattern matters as much as the pain itself.

  • Persistent bone pain

    Deep, aching pain that persists for weeks, is not relieved by rest, and typically worsens at night. A cardinal red flag.

  • Swelling or a palpable mass

    A firm, sometimes tender lump over or near a bone. May grow noticeably over weeks rather than days.

  • Reduced range of motion

    Stiffness or loss of movement in a nearby joint, especially around the knee, shoulder or hip.

  • Pathological fracture

    A break after minimal or no trauma. Should always prompt urgent imaging and specialist review.

  • Reduced weight-bearing or limp

    New, unexplained limp in a child or young adult, or reluctance to use an arm, warrants prompt assessment.

  • Systemic symptoms

    Weight loss, fatigue, night sweats or fever suggest more advanced or Ewing-type disease and need urgent work-up.

  • Skull base or spinal symptoms

    Neurological signs, cranial nerve palsies or unexplained back pain can point to chordoma or spinal involvement.

  • Red flag - night pain plus a mass

    Night pain combined with a palpable lump or a suspicious X-ray must be treated as a bone sarcoma until proven otherwise.

Not everything is cancer

Benign and borderline bone tumours.

Many bone lumps and lesions found on imaging are not malignant. Recognising these patterns helps avoid overtreatment while keeping true cancers on the right pathway.

  • Osteoid osteoma

    Small, painful nidus, classically responsive to NSAIDs. Often treated with radiofrequency ablation.

  • Osteoblastoma

    A larger cousin of osteoid osteoma. Usually needs surgical curettage.

  • Osteochondroma

    The commonest benign bone tumour. Growth after skeletal maturity should prompt review.

  • Enchondroma

    Cartilage lesion, often incidental. Serial imaging distinguishes it from low-grade chondrosarcoma.

  • Aneurysmal bone cyst

    Expansile lytic lesion in young people. Curettage or denosumab in complex cases.

  • Non-ossifying fibroma

    Common incidental finding in children. Almost always resolves without treatment.

  • Fibrous dysplasia

    Focal or polyostotic. Managed conservatively with bisphosphonates in symptomatic disease.

  • Eosinophilic granuloma

    Part of Langerhans cell histiocytosis. Often treated with intralesional steroid.

  • Giant cell tumour of bone

    Locally aggressive, borderline malignant. Managed with surgery and denosumab.

Bone cancer is also very different from cancer that has spread to bone from elsewhere. See our dedicated guide on bone metastasis for cancers of the breast, prostate, lung, kidney, thyroid and myeloma.

Treatment

How bone cancer is treated in the UK.

Treatment is tailored to the tumour type and stage. Every plan is set by a sarcoma MDT and combines systemic therapy, surgery and radiotherapy in the sequence that gives the best chance of cure and function.

  • Osteosarcoma - MAP chemotherapy

    Neoadjuvant high-dose methotrexate, doxorubicin and cisplatin, then surgery, then adjuvant chemotherapy guided by percentage tumour necrosis.

  • Ewing sarcoma - VDC/IE

    Alternating vincristine, doxorubicin and cyclophosphamide with ifosfamide and etoposide, plus local control by surgery, radiotherapy or both. UK trials include EE99 and INTER-EWING.

  • Chondrosarcoma - wide surgery

    Radioresistant and chemoresistant in low grade. Wide en-bloc resection is the mainstay. Proton beam therapy is used for skull base and pelvic disease.

  • Chordoma - surgery plus protons

    Maximal safe resection followed by proton beam therapy at a specialist skull-base or spine centre gives the best local control.

  • Giant cell tumour of bone

    Curettage with adjuvants or wide resection. Denosumab is used to downstage complex tumours or where surgery is not feasible.

  • Limb-salvage surgery

    Endoprosthetic replacement, extendable prostheses in growing children, 3D-printed custom implants, allograft or vascularised fibula reconstruction.

  • Proton beam therapy

    Available in the UK for chordoma, selected chondrosarcoma, close margins, inoperable disease and some Ewing sarcomas near critical structures.

  • Metastatic and relapsed disease

    Combination chemotherapy, metastasectomy where feasible, targeted radiotherapy and immunotherapy trials, all coordinated by the sarcoma MDT.

Red flags

When bone symptoms need urgent attention.

Most bone pain is not cancer. These are the patterns that must be taken seriously and pushed through the urgent pathway.

  • Night pain in a young person

    Persistent bone pain that wakes an adolescent or young adult from sleep warrants urgent plain radiograph and specialist review.

  • Pathological fracture

    A fracture after trivial trauma, or through an area of pre-existing pain, must be imaged and reviewed at a sarcoma centre before fixation.

  • Rapidly enlarging bone mass

    Any firm, deep swelling over bone that grows over weeks needs same-week imaging and referral, not watchful waiting.

  • Suspicious X-ray features

    Cortical destruction, periosteal reaction (sunburst, onion-skin, Codman triangle) or an ill-defined lytic lesion require urgent MRI and referral.

  • Symptoms after prior radiotherapy

    New bone pain in a previously irradiated field, particularly in older patients, can indicate post-radiotherapy osteosarcoma.

  • Paget-related change

    A sudden change in pain pattern or a new lump in a patient with known Paget disease can herald secondary osteosarcoma.

  • Neurological signs

    Progressive back pain with weakness, numbness or bowel or bladder change needs emergency imaging to exclude spinal chordoma or cord compression.

  • Bone pain plus systemic upset

    Bone pain combined with weight loss, fever or unexplained anaemia may point to Ewing sarcoma, myeloma or widespread metastatic disease.

  • Unplanned biopsy elsewhere

    Biopsy or excision of a suspected sarcoma outside a specialist centre can worsen outcomes. Refer first, biopsy later.

Living with it

Life after diagnosis, and long into survivorship.

Bone cancer treatment is intensive and its footprint is long. A good plan looks beyond the first year and considers function, fertility, bone health and mental wellbeing.

A quiet reminder

Fertility conversations should happen before treatment starts.

Sperm banking, egg or ovarian tissue preservation and referral to specialist services are all part of a modern sarcoma pathway.

  1. 01 Team

    Care stays with the sarcoma centre

    All treatment and follow-up run through one of the 15 UK supraregional bone sarcoma centres, working with your local hospital.

  2. 02 Recovery

    Rehabilitation is part of the treatment

    Physiotherapy after limb-salvage or amputation, prosthetic fitting and gait retraining are planned from the outset, not as an afterthought.

  3. 03 Health

    Long-term surveillance

    Ongoing checks for cardiotoxicity from anthracyclines, kidney function, bone health, second cancers and prosthesis integrity.

  4. 04 Support

    You do not have to do this alone

    Charities such as the Bone Cancer Research Trust and Sarcoma UK offer peer support, fertility guidance and psychological help.

Frequently asked

Everything we get asked about bone cancer.

Quick answers on symptoms, biopsy, limb-salvage surgery and proton beam therapy.

  • What is bone cancer?

    Bone cancer usually means a primary malignant tumour arising from bone or cartilage, such as osteosarcoma, Ewing sarcoma, chondrosarcoma or chordoma. Cancer that has spread to bone from elsewhere is called bone metastasis and is a separate topic.

  • How is bone cancer different from bone metastasis?

    Primary bone cancer starts in the bone itself and is rare. Bone metastasis is much more common and comes from cancers of the breast, prostate, lung, kidney, thyroid or from myeloma. The tests overlap, but treatment pathways and prognosis are different.

  • Why is night pain considered a red flag?

    Bone pain from a benign injury usually settles with rest. Persistent pain that wakes a person from sleep, or that steadily worsens over weeks, is one of the most consistent early signs of a primary bone tumour and always deserves imaging.

  • Why must the biopsy be done at a sarcoma centre?

    The biopsy tract can seed tumour cells and needs to be included in later surgery. A poorly planned biopsy can turn a limb-salvage operation into an amputation. UK guidance is clear that biopsy of a suspected bone sarcoma should happen at the treating supraregional centre.

  • What is limb-salvage surgery?

    It is surgery that removes the tumour with a wide margin and reconstructs the limb using an endoprosthesis, allograft, vascularised fibula or a custom 3D-printed implant. Growing children may have an extendable prosthesis. Amputation remains the right choice in some cases and can give excellent function.

  • When is proton beam therapy used for bone cancer?

    Proton beam therapy is offered in the UK for chordoma, selected chondrosarcoma, close or positive surgical margins, inoperable tumours and some Ewing sarcomas near critical structures. It is particularly valuable for skull-base and spinal tumours where sparing nearby nerves matters.
