What should you know about leg osteosarcoma?

Osteosarcoma can cause persistent bone pain, swelling, tenderness, or reduced movement. Pain after activity may progress to pain at rest, but symptoms overlap with injuries and other conditions. The diagnosis is established from a planned biopsy interpreted with imaging, not from symptoms alone.

Scans assess the bone, nearby soft tissue, and possible spread so the team can plan safely. Pathology describes the tumour, while the treatment team considers its position, response to treatment, and effect on function.

Request coordinated care from an orthopaedic oncology team. Chemotherapy may be given before surgery to treat cancer cells beyond the visible tumour and after surgery to address remaining risk. Tumour removal surgery aims to remove the tumour with a safe margin while preserving useful limb function when feasible; reconstruction and rehabilitation may be part of recovery.

Get urgent help for sudden severe pain after a minor injury, inability to bear weight, a new deformity, or a cold, pale, numb foot. During treatment, promptly report fever, chills, uncontrolled vomiting, new breathlessness, or unusual bleeding because these can require same-day advice. Do not delay assessment of persistent or worsening bone pain.

Ask where the tumour is located, what the biopsy shows, whether imaging suggests spread, and how chemotherapy and surgery will be sequenced. Ask about limb reconstruction, expected rehabilitation, fertility concerns, and warning signs to report between appointments.
