Radiation therapy destroys cancer cells or keeps them from growing. High energy X-rays, gamma rays, or proton beams are focused on a tumor. Radiation therapy is done before surgery or afterward to kill any cancer cells left after surgery. Radiation therapy may also be used as the main treatment if surgery is not an option. It can also help relieve symptoms caused by a tumor. There are two main types of standard radiation therapy:
Radiation zeros in on a tumor or cancerous cells. We have experience and resources to deliver therapy safely and protect healthy tissue from radiation therapy:
- Internal radiation therapy: This approach uses a radioactive substance directly targets a tumor and is applied through a needle, wire or catheter. Or it might be delivered using tiny brachytherapy seeds that your surgeon would implant near the tumor.
- External beam radiation therapy: With external beam radiation therapy, you will rest comfortably, lying flat. The radiation machine will slowly rotate around your body. It will deliver a carefully pointed radiation beam at the tumor or cancerous growth. The technology we use at Sylvester Cancer Center achieves pinpoint accuracy. Minimal or no radiation exposure occurs in your healthy body tissue. Types of external beam radiation therapy include:
- 3D conformal radiation therapy (3D CRT): A computer creates a 3D picture of the brain or spinal cord tumor. The highest possible dose of radiation is applied.
- Intensity-modulated radiation therapy (IMRT): This is also a type of 3D radiation therapy. It uses thin beams of radiation of different intensities (strengths). Beams hit the tumor from many angles.
- Stereotactic radiosurgery: This therapy aims a single (larger) dose of radiation directly at a brain tumor. Stereotactic radiosurgery or radiosurgery are other names for this, but it is not technically a surgical procedure.
