Radiation Oncology


Adventist Cancer Institute offers patients close-to-home access to advanced technologies and research programs without the need to travel to a university medical facility.

We offer many of the same clinical trials found in academic settings and we work closely with researchers who are making important discoveries on the vanguard of cancer treatment.

The Adventist Cancer Institute team works closely with the medical oncology and surgery departments, as well as other clinical specialties. Integrated, multidisciplinary programs are established for a variety of cancers, including those of the brain, head and neck, breast, gastrointestinal tract, lung, prostate and other genitourinary system cancers, gynecological tumors, and lymphomas.

Adventist Cancer Institute’s Radiation Oncology department has many advanced technologies to aid in diagnosis and treatment plans, some of which are highlighted below.

Image Guided Radiation Therapy (IGRT)

Intensity Modulated Radiation Therapy (IMRT)

Intensity Modulated Radiation Therapy (IMRT) is a treatment in which the intensity of the radiation can be changed during treatment to spare normal tissue around the areas of the tumor. Ultimately, IMRT leads to less damage to healthy tissue around the treatment area, very precise targeting and treatment to the tumor, and a better quality of life for the patient.


Brachytherapy is internal radiation therapy where radiation is received internally rather than externally like IMRT or stereotactic radiosurgery. It is most often used for prostate treatment, but can also be used for treatment of the head, neck, breasts, uterus, thyroid, ovary and cervix. 

Stereotactic Radiosurgery

This procedure is used in order to give a high dose of radiation to a brain lesion. It is a non-invasive alternative to brain surgery. Stereotactic Radiosurgery uses a head frame/helmet that helps the neurosurgeon and radiation oncologist to both steady your head and to mark the exact treatment area so that the lesion receives the most radiation and the surrounding area receives very little. Because stereotactic radiosurgery uses no incisions, recovery is much easier for the patient. In fact, many people return to their normal activities the next day. Results show that the lesion will shrink over time and in some cases, completely disappear up to 60 minutes to complete and the helmet is removed.

Prostate Ultrasound

Working with Varian’s SonArray, the prostate ultrasound is a technology featured at the Adventist Cancer Institute. In order to give patients the best treatment for prostate cancer, the ultrasound allows the therapist to make sure that the radiation is given at the exact location of the tumor for each treatment. Doing this confirms that the radiation will be received by the tumor and that little healthy tissue is affected.

Radionuclide Therapy / Radioisotopes

Radionuclide therapy is a type of radiation therapy using radioactive materials to treat disease. The radioactive material is concentrated in the area of the body needing treatment and is given by mouth, injection or infusion. 

External Beam Radiation Conformal Therapy

3-Dimensional Conformal Radiotherapy is a technique in which the profile of each radiation beam is shaped to fit the profile of the target. When the treatment volume conforms to the shape of the tumor, the relative toxicity of radiation to the surrounding normal tissues is reduced, allowing a higher dose of radiation to be delivered to the tumor than conventional techniques would allow.

Superficial Treatment

Orthovoltage is a low-voltage radiation treatment for skin cancer. In Superficial Microwave Hyperthermia, a probe is laid on the skin and heats the tissue to kill unhealthy cells.

Portal Imaging

Technicians at the Adventist Cancer Institute use portal imaging, a digital x-ray technique for positioning before treatment is delivered.
