Stereotactic Gamma Ray Surgery for Extracranial Lesions and Tumors


Stereotactic gamma ray surgery is used to treat lesions and tumors that grow in areas of your body outside your head. These abnormal cells can grow in areas such as your lungs, liver, spine, pancreas, kidneys, and prostate. They can be benign (not cancer) or malignant (cancerous). Beams of radiation kill the tumor cells. Normal tissues near the tumor get little or no radiation. You may have one treatment using high energy beams, or many treatments using weaker beams.


Follow up with your healthcare provider as directed:

Ask your healthcare provider if and when you need to return for more gamma ray treatments. If you need other treatment sessions, you may be asked to return in 1 week. Write down your questions so you remember to ask them during your visits.

Contact your healthcare provider if:

  • You have a fever.
  • You notice a change in how you feel and move parts of your body.
  • You have dizziness or nausea, or you are vomiting.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • Your symptoms come back.
  • You suddenly feel lightheaded and short of breath.
  • You have chest pain when you take a deep breath or cough. You cough up blood.
  • Your arm or leg feels warm, tender, and painful. It may look swollen and red.
