Understand this condition

Brain metastases occur when a cancer from another organ spreads to the brain, unlike a primary brain tumour.

How it is assessed

Brain MRI, the primary cancer, symptoms, and lesion number and size guide planning. Tissue assessment may be considered when diagnosis is uncertain.

Care pathways

Surgery, focused or broader radiation, systemic treatment, and symptom care depend on the overall picture, including disease outside the brain.

Important distinctions & limits

Lesion count alone cannot select treatment. Location, volume, cancer type, previous care, and patient function also matter.

One diagnosis, several care specialties

Read the video transcript
  1. Understand the disease type first. An organ name is not enough. Pathology, stage, and general condition give context.
  2. Each specialty has a role. Medical, radiation, and surgical oncology may work together according to the case.
  3. An MDT brings perspectives together. A multidisciplinary team discusses findings and options. Team composition depends on the case.
  4. Bring clear questions. BKC supports coordination. Diagnosis and medical decisions remain with licensed clinicians.
