Brain Tumors

Understanding primary and metastatic brain tumors.

Patient Guide

Brain Tumors

Brain tumors may begin in the brain or spread there from cancer elsewhere in the body. The diagnosis and treatment plan depend on the tumor type, grade, number, size and location; molecular or pathology findings; symptoms; overall health; and prior treatment.

Brain Tumor Treatments

Dr. Linson may use IMRT, SBRT, SRS or whole-brain radiation to treat a brain tumor. The recommended approach depends on whether the tumor is primary or metastatic, its type, number, size and location, prior treatment, symptoms and the goals of care.

  • IMRT (Intensity Modulated Radiation Therapy) shapes radiation from multiple directions to conform the dose to the treatment area while limiting exposure to nearby healthy tissue.
  • SBRT (Stereotactic Body Radiation Therapy) delivers highly focused radiation in a small number of treatments and may be considered for selected targets.
  • SRS (Stereotactic Radiosurgery) is a precise, non-surgical treatment commonly delivered in one session or a few closely related sessions for selected brain tumors.
  • Whole-brain radiation treats the entire brain and may be considered when there are multiple tumors, widespread involvement or other clinical reasons.
  • Radiation may be used alone or coordinated with surgery, chemotherapy, targeted therapy, immunotherapy or supportive care, depending on the diagnosis.

How We Keep Your Treatment Accurate

  • A fitted thermoplastic mask keeps the head in a precise, repeatable position. Tell the team before simulation if you are claustrophobic.
  • CT simulation maps area of the brain to be treated.
  • The physician defines the target and area to protect; the dosimetrist and medical physicist create and verify the plan.
  • Image guidance confirms tumor location and positioning before radiation is delivered.

Before the First Treatment

  • Complete your consultation.
  • Complete CT simulation and individualized treatment planning.
  • The care team completes dose calculations and quality checks.

During Treatment

  • Brain swelling may occur and can be treated with a corticosteroid such as dexamethasone. Take it exactly as prescribed and never stop suddenly unless your prescriber directs you.
  • Hair loss may occur in the treatment area and may begin several weeks after treatment.
  • Fatigue is common; prioritize activities, pace yourself and balance gentle activity with rest.
  • Contact the care team immediately for a seizure, new weakness, confusion, severe or worsening headache, repeated vomiting, speech or vision changes, loss of balance or another sudden neurologic change. Call 911 for a medical emergency.

After Treatment

  • Fatigue and treatment-area effects may continue for a period after radiation. Hair loss, when it occurs, may begin several weeks after treatment starts and regrowth varies. Brain swelling and neurologic symptoms require individualized monitoring.
