What should you know about multiple bone metastases?

Bone metastases may occur when cancer cells travel from an original tumour to bone. They can alter the normal balance between bone breakdown and repair, making an area painful or fragile. The spine, pelvis, ribs, and long bones are commonly assessed because disease there can affect movement, stability, or nearby nerves. Some people have no bone symptoms when deposits are found on imaging.

Cancers that can spread to bone include breast, lung, and prostate cancer, among others. Scans, blood tests, and sometimes a biopsy help clarify the pattern. A diagnosis of bone metastases is different from cancer that began in bone, and the treatment plan depends on the original cancer and the affected sites.

Tell the team where pain occurs, whether movement changes it, and whether you have weakness, numbness, or falls. Treatment may combine cancer-directed medicines with [Bone-Strengthening Therapy](/treatments/supportive-and-palliative-care/bone-strengthening-therapy/), [Cancer Pain Management](/treatments/supportive-and-palliative-care/cancer-pain-management/), or [Palliative Radiotherapy](/treatments/radiation-oncology/palliative-radiotherapy/) for a painful area. A physiotherapist may advise safer movement and equipment.

Ask before starting strenuous exercise, lifting, or manual therapy over a fragile area. Keep dental care and kidney problems in the discussion when bone-strengthening medicines are considered. The goal may include controlling the cancer, protecting mobility, easing pain, and preventing avoidable injury.

Seek urgent medical help for new leg weakness, numbness around the groin, loss of bladder or bowel control, or severe back pain, because these may signal pressure near the spinal cord. Contact the team quickly for sudden severe bone pain, inability to bear weight, a fall with persistent pain, marked thirst, vomiting, or unusual confusion.

Ask which bones are involved, whether the spine or a weight-bearing bone needs protection, and what activity is safe. Ask how pain will be treated, whether radiotherapy or bone-strengthening therapy fits, how treatment will be monitored, and which symptoms require emergency help.
