Radiation Oncology

Our radiation oncologist can provide treatment through several forms, including conventional external beam therapy, intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT).

A new Varian Trilogy Linear Accelerator with OnBoard Imaging (OBI) and Stereotactic Body Radiation Therapy (SBRT) was put in operation in January 2014, providing highly advanced radiation treatment. The OBI (a built-in CT scanner) enables medical staff to provide highly focused doses of radiation therapy directly to tumors while sparing healthy surrounding tissue, which can reduce the number of radiation treatments needed in some cases.


Some cancer patients experience lymphedema, or swelling of body tissues as a result of treatment. Our lymphedema specialist can treat this condition with specialized massage, compression garments and exercise regimens.

Surgery for Cancer

Surgeons at Bozeman Health perform a number of types of conventional surgery from diagnostic (biopsy) to staging (determining the size of the tumor and where it has spread) to tumor removal. In some cases, when the entire tumor cannot be removed, surgeons will remove as much as possible. Reconstruction and preventive surgery may also be performed. In certain cases, minimally invasive surgery may be performed, including laparoscopic, laser, and cryosurgery and endoscopy procedures.
