Lung cancer with spread to the brain

There is a lesion in the brain. How does this change the therapy plan?

Brain involvement changes therapeutic considerations as it influences symptoms, the choice of drugs that penetrate the blood-brain barrier, and the feasibility of targeted radiotherapy.

Upload Medical ReportPrepare questions for your doctor

Not a diagnosis and not final medical advice. Must be reviewed by a doctor.

What changes at this stage

  • The number and size of lesions determine whether targeted or whole brain radiotherapy is discussed.
  • Drugs that penetrate the blood-brain barrier are a consideration in selection.
  • Corticosteroids and anti-seizure medications may be part of symptom management.

Options that are usually discussed

  • Stereotactic radiotherapy to limited lesions

    SRS may be discussed when the lesions are few in number and limited in size.

  • Selection of drugs with penetration into the brain

    Some targeted inhibitors are selected because of their penetration into the central nervous system.

  • Symptom control

    Management of edema and neurological symptoms is part of the plan.

The decision remains with your doctor

This page explains the options that may be discussed; it does not choose one for you.

Practical next steps

  • Ask how many lesions are in the brain and how they are assessed.
  • Discuss whether SRS or whole brain radiotherapy is being considered.
  • Ensure symptom management and monitoring of anti-seizure medications is clear.

Questions for your oncologist

  • How many lesions in the brain are there and does their size allow for SRS?
  • Can the proposed drug reach brain tissue?
  • How will neurological symptoms be monitored?
  • What is the sequence between radiotherapy and systemic therapy?
