Radiation oncology: Attacking cancer with the most advanced radiation therapies

At UW Health, we offer some of the most advanced radiation treatments available. In fact, we helped develop some of them. Our treatments are designed to aggressively attack cancer cells but avoid healthy tissues. This allows us to reduce common radiation side effects.

Programs and research

Looking to the future of radiation therapy

Important discoveries have improved today’s radiation therapy options. They’ve helped improve treatment and make it easier for patients.

Though we offer the best available technologies, we look to make things even better for future patients through active research.  Our team is involved in many clinical trials to discover new and improved ways to deliver radiation therapies and reduce side effects. As a patient at UW Health, you may have access to these trials.

Cancers we treat

Radiation Oncology uses high-energy beams such as X-rays and charged particles to treat cancer. We sometimes give this treatment alone. Other times, we combine it with surgery and/or chemotherapy.

We are also one of the leaders in brachytherapy, a radiation source inside the body close to your tumor.

Types of cancers treated through radiation therapy

Radiation may be helpful with many types of cancer, including:

  • Bladder cancer

  • Brain tumors

  • Breast cancer

  • Gastrointestinal cancer

  • Gynecologic cancer

  • Head and neck cancer

  • Liver cancer

  • Lung cancer

  • Lymphoma

  • Pediatric cancer

  • Prostate cancer

  • Sarcoma

Radiation may also be helpful with metastatic cancer, cancer that has spread to other parts of the body.


We offer several different types of radiation therapy as well as different forms of treatment within each type.

Radiation therapy

Radiation therapy can be used for many types of cancer. Doctors may use it to:

  • Help your cancer go away completely 

  • Lower the risk of your cancer returning or spreading elsewhere in your body 

  • Reduce symptoms of advanced cancer

  • Shrink a tumor before you have surgery 

  • Treat cancer that has returned

Involves placing a radiation source inside the body close to your tumor. Sometimes we leave the radiation source for a short time and then remove it. Other times it remains in your body. We offer:

  • Accelerated partial breast irradiation

  • Cervical cancer brachytherapy

  • Lung mesh brachytherapy

  • Melanoma eye plaque

  • Prostate seed implantation

  • Vaginal cuff brachytherapy (uterine cancer)

Delivers X-ray beams to a tumor from outside your body.

  • 3D conformal radiation therapy

  • Fractionated stereotactic radiation therapy

  • Image-guided radiation therapy

  • Intensity modulated radiation therapy (IMRT)

  • Pulsed reduced-dose rate radiation therapy

  • Stereotactic body radiation therapy (SBRT)

  • Stereotactic radiosurgery

  • TomoTherapy CT-image guided radiation

  • Total body irradiation

  • ViewRay MRI-guided radiation

  • Whole-brain radiation therapy

Delivers radiation intravenously with drugs or special beads which target cancer tissue.

  • Beta-Cath

  • Quadramet (Samarium-153)

  • Theraspheres (Yttrium-90)

  • Xofigo (Radium-223)

Before treatment: What to expect

Radiation oncologists from the UW Carbone Cancer Center have put together the following information to help you better understand the radiation treatment process.

Before deciding if you would like to receive radiation therapy treatments, you must first meet with a radiation oncologist to help decide if radiation therapy is right for you.

During your consult, you will first meet with a nurse. The nurse will take you into an exam room to record your weight, vital signs, medications, and allergies.

Next you will meet with the doctors - typically a radiation oncology resident and radiation oncologist will meet with you. They will examine you and ask you questions. You may be asked about your current medical problems, past medical history, past surgical history, medications, and lifestyle.

Treatment options, as well as the benefits and risks of these options, will be discussed with you. If radiation therapy treatments are indicated, the doctors will talk to you about treatment plans. If you decide that radiation therapy is right for you, you will be scheduled for a planning CT scans and/or simulation.

Other staff members you may meet during your consult visit are: medical students, radiation therapy students, nurse practitioners, physician assistants, and research associates.

In order for the radiation beams to be effective, they must be aimed at the same target for each treatment. The process of measuring your body and marking your skin to help your team direct the beams is called a simulation or treatment planning CT scan.

During a simulation or treatment planning CT scan, you will be positioned on the table the same way you will be for treatment. Because positioning is so important for your treatment, you may have a special mask or mold made. The radiation therapists will mark the area on your body that the doctor wants to be treated with radiation therapy and take X-ray images of the area. Depending on the area treated, your physician may request that you receive IV contrast or barium to drink.

Contrast is used to highlight organs so that they can be seen on X-ray or CT images. After your X-rays or CT scans are completed the radiation therapist will mark your skin with a set of small, permanent tattoos. The tattoos will be used to position you each day for your radiation treatments.

Once you have finished with your treatment planning CT or simulation, your radiation oncologist and other members of the treatment team review the information. Tumors are not regular - they come in different shapes and sizes. To design the radiation therapy to the size, shape and location of your tumor, your treatment team (radiation oncologists, residents, medical physicists and dosimetrists) uses computers and your treatment planning images to plan your treatment.

Depending on the complexity of your treatment, this step can take anywhere from two days to two weeks. After reviewing all of your information and your treatment plan, your doctor will write a prescription that outlines exactly how much radiation you will receive and what parts of your body will receive the radiation.

During treatment: What to expect

The radiation therapist will give your treatment following your radiation oncologist’s instructions. The first day of treatment will take approximately 45 minutes. After the first day, your treatments will take approximately 15-30 minutes. The radiation therapists will help you lie down on the table in the same position you were in for the treatment planning CT or simulation. They will be using the tattoos that were placed on your skin during your treatment planning appointment to help position you and may make shifts according to your treatment plan.

Once you are positioned, the radiation therapist will take X-rays (also called port films). Port films are taken on the first day of treatment and once a week. The port films are used to check your positioning and do not show if any disease is present. After your doctor reviews the port films, you will receive the first treatment. During the port films and your treatments, the therapists will step out of the room. They are closely monitoring you on a television screen while giving your radiation.

There is a microphone in the treatment room so you can always talk with the therapist if you have any concerns. The machine can be stopped at any time if you are feeling sick or uncomfortable. During your treatment, the therapist may move the treatment machine or treatment table. The machine might make noises during treatment that sound like clicking, knocking or whirring but the radiation therapist is in complete control of the machine at all times.

During radiation therapy, your radiation oncologist and nurse will see you regularly to follow your progress, evaluate any side effects, and address any concerns you may have. You may want to bring a family member or friend with you to these appointments.

After treatment follow up

After treatment is completed, follow-up appointments will be scheduled so that your radiation oncologist can make sure your recovery is proceeding normally and can continue to monitor your health. Your doctor may order labs, X-rays and other diagnostic tests.

As time goes by, the number of times you need to visit your radiation oncologist will decrease. However, please know that your radiation oncology team will always be available if you need to speak to someone about your treatment.
