Radiation therapy can shrink or kill tumor cells. We may recommend radiation therapy if surgery isn’t an option for you.
Image-Guided Radiation Therapy
Radiation therapy uses high-energy beams to treat cancer. Image-guided radiation therapy (IGRT) can treat tumors with even more accuracy than traditional radiation therapy. IGRT involves taking many images of the tumor during treatment with a CT scan or X-rays. Your body is imaged in real time, so we can correct for any motion during treatment. IGRT lets your care team deliver radiation with great accuracy and precision.
Stereotactic Body Radiation Therapy
Stereotactic body radiation therapy (SBRT) is a form of treatment that delivers precise, high-radiation doses in 3 to 5 treatment sessions. It targets a small area with high doses of radiation and lower doses to the normal tissue around it. You can receive higher doses to the tumor at each treatment session, which shortens the overall treatment period.
This treatment is not invasive. You can usually have it as an outpatient, without a hospital stay.
The side effects from IGRT and SBRT often are mild. The radiation dose is precise and very concentrated, which is the best way to eliminate kidney cancer cells.
For patients who cannot have surgery to remove kidney cancer, we may offer targeted SBRT instead. We also can use these treatments on areas where the cancer has spread (metastasized), such as the bone or spine.
