Does brain metastases cause persistent headache?

Brain metastases may produce headache through pressure, irritation, or swelling around a tumour. Many non-cancer conditions also cause lasting headaches, so the pattern and accompanying symptoms guide assessment.

Tell the care team about a headache that is new, steadily worsening, wakes you from sleep, feels different from previous headaches, or becomes more noticeable with coughing, bending, or straining. Mention nausea, vomiting, balance problems, weakness, confusion, or vision and speech changes.

Clinicians consider the headache history, neurological examination, cancer type, current treatments, and medicines. They may arrange brain imaging when the findings suggest that the brain needs closer evaluation.

Contact your oncology team about a persistent or changing headache instead of repeatedly increasing pain medicine yourself. Record when it occurs, where it hurts, what makes it worse, which medicines you took, and whether other symptoms appeared.

Take prescribed medicines exactly as directed. If steroids are being used for brain swelling, do not stop them suddenly unless the prescribing clinician gives a tapering plan.

Seek emergency care for a sudden severe headache, a first seizure, fainting, marked confusion, new weakness or numbness, difficulty speaking, loss of vision, or repeated vomiting. These signs need rapid assessment regardless of whether brain metastases have been diagnosed.

A headache following a fall or head injury also warrants urgent advice, especially when the person takes medicine that affects blood clotting or becomes drowsier than expected.

Ask whether the headache pattern suggests brain swelling, whether imaging is appropriate, and which pain medicines can be taken safely with your cancer treatment.

It also helps to clarify which symptom changes should trigger an emergency call, whom to contact after hours, and how any treatment for a brain lesion may affect the headache.
