Lung cancer with bone metastases: what to know

Bone metastases may affect the spine, ribs, pelvis, or limbs. Some people have aching pain, tenderness, reduced movement, or pain that is worse at night; others have no bone symptoms and learn about the spread through scans. Bone can become weaker, and blood calcium can rise, causing thirst, constipation, nausea, drowsiness, or confusion. The location and strength of the affected bone matter when planning care. This finding is serious, but it does not by itself determine one person's future course.

Tell the oncology team about new or worsening pain, changes in walking, or difficulty using an arm or leg. Imaging can show which bones are involved and whether a joint or vertebra needs protection. Treatment may include systemic therapy for the lung cancer, radiotherapy to a painful or vulnerable area, medicines that support bone health, or surgery when a bone needs stabilising. Gentle movement and a tailored activity plan may help, while high-impact activity should be discussed if a bone is fragile. Palliative care can support pain, sleep, mobility, and emotional wellbeing alongside cancer treatment.

Call emergency services or seek immediate care for sudden severe back pain, new leg weakness or numbness, loss of bladder or bowel control, inability to stand, or a suspected fracture. These may signal spinal cord pressure or structural damage. Seek prompt medical advice for increasing thirst, vomiting, constipation with drowsiness, or new confusion, which can occur when calcium rises.

Which bones are affected, and are any at risk of breaking? Do I need an urgent scan? What pain plan is appropriate? Would radiotherapy, bone-strengthening medicine, or surgery help? Which activities are safe? Who should I contact outside clinic hours?
