What should you know about metastatic prostate cancer spine?

When prostate cancer spreads to the spine, cancer cells can grow in the bones of the vertebrae. This may cause persistent or worsening back or neck pain, pain that travels into an arm or leg, or a vertebra that becomes vulnerable to collapse. Pressure on the spinal cord or nearby nerves can affect strength, sensation, balance, and bladder or bowel control.

The symptom of difficulty passing urine can have several causes, including prostate or nerve-related problems; it does not by itself establish spinal spread. Assessment may include a neurological examination and imaging chosen by the clinical team. More background is available in [Prostate Cancer](/conditions/prostate-cancer/).

Treatment depends on the location and extent of disease, bone strength, nerve involvement, previous treatment, and your general health. Options may include medicines that treat prostate cancer throughout the body, radiotherapy to a painful or threatening spinal area, and bone-strengthening therapy. In selected situations, surgery may stabilise the spine or relieve pressure. Your team may also recommend pain relief, a brace, physiotherapy, or activity changes.

Ask whether imaging shows spinal cord pressure or an unstable vertebra, how quickly treatment should begin, and which movements are safe. Possible treatment approaches include [Radiotherapy](/treatments/radiation-oncology/radiotherapy/), [Targeted Radioisotope Therapy](/treatments/radiation-oncology/targeted-radioisotope-therapy/), and [Bone-Strengthening Therapy](/treatments/supportive-and-palliative-care/bone-strengthening-therapy/).

Seek emergency medical help for new or rapidly worsening leg or arm weakness, numbness around the inner thighs or buttocks, inability to walk, loss of bladder or bowel control, or severe back pain after a minor movement or fall. These can signal spinal cord compression or a fracture. Do not wait for a routine appointment; tell the emergency team that you have prostate cancer and describe when the change began.

Ask which vertebrae are involved, whether the spinal cord or nerve roots are under pressure, whether the spine is stable, and what imaging is needed. Discuss the goals and timing of radiotherapy, systemic treatment, bone protection, or surgery, along with safe activity, pain control, and symptoms that should trigger an immediate call.
