Radiation therapy

The type of therapy you receive will depend on your condition, your personal health and several other factors, but options include:

• 3D conformal radiation therapy (3D-CRT) — This type of radiation uses 3D computerized tomography (CT) scans to determine the exact shape and size of tumors, then precisely treat the tumor while minimizing damage to surrounding healthy tissue.
• Brachytherapy — With this treatment, we implant seeds, or radioactive sources, near tumors or adjacent areas to destroy cancer cells locally.
• Intensity modulated radiation therapy (IMRT) — This therapy uses multiple radioactive beams with different intensities to deliver the highest dose to the tumor, while minimizing exposure to surrounding healthy tissues.
• Intraoperative radiation therapy (IORT) — A specialized radiation device delivers a high radiation dose to the exposed target during a surgery. Healthy tissues can often be protected by using shielding materials or moving them out of the way.
• Stereotactic body radiation therapy (SBRT) — This type of radiation uses precise imaging, in conjunction with high-intensity radiation beams, usually in three to five treatments, most commonly for tumors in the lungs, spine, liver and prostate
• Stereotactic radiosurgery (SRS) — This is a noninvasive, nonsurgical treatment uses multiple high-intensity beams to deliver extremely precise radiation doses to tumors in the brain during a single treatment.
• Volumetric modulated arc therapy (VMAT) — Our specialists use a linear accelerator that rotates around you while delivering intense, highly-precise and modulated radiation beams to tumors while minimizing side effects.
• Y-90 radioembolization — This therapy injects microscopic beads with radioactive material into the blood vessels that supply blood to a liver tumor. The microbeads shrink the tumors and block the blood supply to cancerous cells.

Our cancer care team consists of many experts coming together to ensure the best possible care for you. If your oncologist recommends radiation treatment for cancer, we want you to know what to expect so we can address your concerns as soon as they come up.

Initial consultation with a radiation therapist

After registration, you will have a consultation with your radiation oncologist. They will explain the diagnosis and the reason radiation therapy is necessary, as well as how many treatments are needed and what side effects to expect. From there, you will schedule a radiation therapy planning appointment.

Radiation therapy planning

Radiation therapy planning firstly requires a CT scan. After the CT scan is complete, the radiation therapist schedules your next visit.

Radiation therapy planning is quite complex and can take several days to complete. Although we understand the urgency to begin treatment, we are very careful to take the time to create an optimized plan for you. This will ensure your safety and maximize the treatment's effectiveness.

Treatment setup verification

During your next visit, we verify your treatment setup. The first session is not a radiation treatment, as it is used to ensure your treatments will be exactly as your doctor has planned.

At the end of your verification session, the radiation therapist will explain the process of your daily check-in for treatments. Treatments then typically begin within a few days.

Daily radiation treatments

Radiation treatments are delivered on consecutive weekdays, with weekends off. Treatments can be as short as 5 minutes or as long as 30 minutes, but your therapists will let you know approximately how long they will take.

The medical staff will see you at least once a week during your course of radiation therapy. These visits are brief, symptom-management checks and typically last five minutes.

Family members are not permitted to observe radiation treatments. We understand you may want to share this experience with loved ones, however, to prioritize patient privacy and guest safety, we ask only you be present for treatments.
