Stereotactic Body Radiation Therapy (SBRT)

Radiation Oncology Helps Patients Fight Cancer

Stereotactic Body Radiation Therapy, or SBRT for short, is a precisely targeted high dose of radiation is delivered to the tumor in 4 -5 treatments over the course of 10-14 days as opposed to several weeks of treatment with conventional radiation therapy every weekday.
SBRT can be applied to certain tumors involving the lungs, the liver, pancreas and spine.

SBRT requires a team of experts, including a radiation oncologist, a radiation physicist, a dosimetrist and two radiation technologists in order to plan and deliver the treatment.

To pinpoint the cancer, they rely on precise images from a CT or computed tomography scanner, which gives cross-sectional pictures of the body, and lasers of the linear accelerator line up the correct coordinates created by the team.

SBRT works in the same way as other forms of radiation treatment. It does not actually remove the tumor; rather, it damages the DNA of tumor cells. As a result, these cells lose their ability to reproduce and ultimately die.

SBRT is an important alternative to invasive surgery, especially for patients who are unable to undergo surgery and for tumors that are hard to reach or are located close to vital organs.
