Deep-seated tumors in inaccessible areas can be treated effectively with gamma knife (Stereotactic Radiosurgery). It is an alternative to conventional surgeries that offers better success rates due to its various advantages.
The first thing to understand regarding gamma knife is that it is not a surgery. It is a non-invasive procedure during which focused radiation is delivered to the targeted site to kill tumors. It kills only tumor cells and spares the healthy cells.
If the procedure is used only for treating brain tumors and other conditions in the head with 192 beams of radiation, it is called gamma knife radiosurgery. When it deals with tumors outside the central nervous system, it is called Stereotactic Body Radiation Therapy (SBRT).
Gamma knife (Stereotactic radiosurgery) has several advantages as opposed to conventional surgery:
No pain
No bleeding
No surgical cuts
No harm to healthy tissues
Accurate targeting of tumor
Lesser time
Minimum exposure to radiation
Fewer side effects
More effective for old patients.
If you are wondering what to expect during the procedure, then there is no need to worry. It is a daycare procedure that lasts for 20-40 minutes. A frameless thermoplastic mark is attached to the patient’s head to hold it in place. Then, an MRI or a CT scan is done to find the exact location of the tumor. Based on the type and location of the tumor, the radiation dose is calculated and delivered appropriately. The patient can go back home on the same day.
