Metastatic bone disease: symptoms, diagnosis and modern treatment options

Metastatic bone disease occurs when cancer spreads from its original site to the bones. It is a common complication of several cancers and can significantly affect quality of life if not managed appropriately.

In this article, Mr Jonathan Stevenson, a specialist in orthopaedic oncology and complex arthroplasty, outlines the key symptoms of bone metastases, how the condition is diagnosed, and the latest treatment options for metastatic bone disease, including advanced surgical approaches.

What is metastatic bone disease?

Metastatic bone disease refers to cancer that has spread (metastasised) to the skeleton from another part of the body, such as the breast, prostate, lung, or kidney. The spine, pelvis, ribs, and long bones of the arms and legs are most commonly affected.

Rather than being a primary bone cancer, these tumours retain the characteristics of the original cancer. This distinction is essential, as it determines both diagnosis and treatment planning.

Common symptoms of bone metastases

The symptoms of metastatic bone disease can vary depending on the location and extent of bone involvement, but several key features are commonly observed.

Pain

The most frequent symptom is persistent bone pain, often described as a deep, aching discomfort that may worsen at night or with activity.

Fractures

Bones weakened by metastases are more prone to breaking, sometimes with minimal trauma. These are known as pathological fractures.

Reduced mobility

Patients may experience difficulty walking or using a limb, depending on the location of the affected bone, contributing to reduced independence.

Other signs

If the spine is involved, patients may develop spinal cord compression symptoms, including weakness, numbness, or bowel and bladder dysfunction. This requires urgent medical attention.

How is metastatic bone disease diagnosed?

Diagnosis typically begins with imaging. X-rays can identify bone damage, but more detailed scans such as MRI or CT are often required. Bone scans or PET scans may be used to assess the full extent of skeletal metastases.

Biopsy

In selected cases, a biopsy is required to confirm the diagnosis and identify the origin of the cancer.

Blood tests

Blood tests can help assess general health and detect abnormalities associated with bone involvement.

Treatment options for metastatic bone disease

Management of metastatic bone disease is individualised and delivered by a multidisciplinary team, including oncologists, radiologists, and orthopaedic surgeons.

Radiotherapy

Radiotherapy for bone metastases is highly effective for relieving pain and controlling local tumour progression.

Systemic therapies

These include chemotherapy, hormone therapy, targeted therapy, or immunotherapy, depending on the primary cancer type.

Bone-strengthening medications

Agents such as bisphosphonates or denosumab are used to strengthen bone, reduce complications, and lower the risk of fractures.

Surgical management

Surgery is indicated when there is a high risk of fracture, an established fracture, or significant pain that has not responded to non-operative measures.

Types of procedures

• Stabilisation (internal fixation): metal implants are used to reinforce weakened bones and prevent or treat fractures.
• Joint replacement (arthroplasty): in cases involving joints, damaged bone may be replaced with a prosthesis to restore function.
• Complex reconstruction: in selected patients, advanced reconstructive techniques can provide durable stability and improved mobility.

Modern orthopaedic oncology surgery enables many patients to maintain independence and achieve meaningful improvements in quality of life.

Living with metastatic bone disease

Effective pain management in metastatic bone disease is central to care and may involve medication, radiotherapy, or surgery.

Physiotherapy and rehabilitation play an important role in maintaining mobility, strength, and function.

Regular follow-up is essential to evaluate treatment response and identify any new areas of concern.

A one stop diagnostic service

Mr Stevenson offers a streamlined one stop diagnostic approach allowing patients to undergo rapid clinical assessment imaging including X-rays, MRI and CT, and a biopsy in a single visit where appropriate to avoid waiting times multiple appointments and to speed of decision-making.

With this integrated approach the diagnostic process can be reduced from months to weeks and provide earlier reassurance and prompt treatment planning. If you have any concerns about a suspected secondary/metastatic bone tumours early specialist assessment is key to achieving peace of mind and optimal care
