Answer to your Health Question


Dear Dr,

My friend has lung tumor and has metastasized to bone and may be brain.

Dr has suggested Intervention therapy to remove satellites cancers and Gamma Seeds therapy.

Can you please give me more details in gamma seeds therapy and what does it actually mean by "Intervention therapy to remove satellites cancers"?

Thank you very much in advance and hope to hear from you soon.

Best regards.


Radioactive Seed Therapy it is a newer, minimally invasive approach to treating high risk patients with Stage I non-small cell lung carcinoma (NSCLC) that may significantly reduce the risk of local disease recurrence.

Developed at Allegheny General Hospital (AGH) in Pittsburgh over the past decade, the procedure involves removing only the cancerous section of the lung and enveloping the surgical site in a mesh material that is embedded with radioactive seeds.

The seeds emit a low dose of radiation over a prolonged period of time in an effort to eradicate any remaining cancer cells.

The surgery is a type of lumpectomy of the lung. Then surgeons zap the cancerous spot with a more precise type of radiation that can kill any leftover cancer cells without damaging the rest of the lung.

What are commonly referred to as seeds are actually tiny metallic cylinders made of titanium, 4.75mm by 0.75mm diameter. They contain a radioactive material which is either Iodine 125 or Palladium 103 isotope.

Iodine 125 and Palladium 103 are man-made radioactive materials created through the use of a machine known as a cyclotron. Once the radioactive material has been created, it is encased in a titanium shell which is then microscopically welded in order to completely retain the radioactive source.

A satellite cancer is a cancer that has spread from the primary tumor.

Interferon gamma-1b as Therapy for Idiopathic Pulmonary Fibrosis.

Gamma Knife therapy is a treatment using gamma rays, a type of high-energy radiation that can be tightly focused on small tumors.

Surgery often can effectively remove bone cancer.

Surgery to remove a benign brain tumor may resolve the problem without the necessity of any further treatment.
