What should you know about bone cancer symptoms?

Pain may be intermittent at first and later become more constant. It can be worse during activity or at night. A tumour near a joint may restrict movement or cause a limp, while one close to a nerve may cause altered sensation or weakness. The pattern depends on the tumour’s site and size.

Muscle strain, arthritis, injury, infection, and non-cancerous bone conditions can all cause pain or swelling. Bone cancer is one possible explanation for persistent focal symptoms, not the default explanation. A clinician considers the location, duration, progression, examination findings, and any relevant medical history.

Primary bone cancer starts in bone. This differs from bone metastasis, where cancer cells have travelled from another organ. Establishing which process is present matters because the treatments are planned according to the tumour’s tissue of origin.

Make an appointment if localised bone pain persists, keeps returning, worsens, wakes you, or interferes with walking, work, or sleep. Seek review as well for an enlarging firm swelling or a limp without a clear reason. Note when the problem began, any injury, triggers, night symptoms, and changes in function.

The clinician may examine the limb or affected region and arrange an X-ray. Depending on the result, further imaging can define the bone and nearby tissues. A biopsy is needed to confirm a suspected bone tumour and identify its type; treatment should be planned by an appropriate specialist team after diagnosis.

Get urgent help for sudden severe bone pain, a snap or crack followed by inability to move or bear weight, or a limb that looks deformed. These signs may indicate a fracture and require immediate protection of the area and medical assessment.

New back or neck pain with limb weakness, numbness, trouble walking, or loss of bladder or bowel control also needs emergency assessment because the spinal cord or nerves may be compressed. Do not drive yourself if weakness or severe pain makes travel unsafe.

Consider asking what the examination suggests, which imaging is appropriate, and when results will be reviewed. If a scan shows a bone lesion, ask whether comparison with older images is useful, whether referral to a bone-tumour team should come before biopsy, and what activity is safe while the bone is being assessed.
