Image-Guided Superficial Radiotherapy

Image-Guided Superficial Radiotherapy (IG-SRT) is a low-dose radiation treatment that very effectively destroys non-melanoma skin cancer with a 99.3% cure rate..  There is no need for anesthesia, minimal risk of infection or scarring, and no need for reconstructive plastic surgery. Patients heal quickly and don’t have downtime or lifestyle restrictions following treatment.

Am I radioactive, and is my treatment dangerous to myself or others?

No, you are not radioactive and your treatment is very safe.

Does the treatment penetrate bone?

No, the treatment only penetrates a few millimeters into the patient’s tissue and has little effect on normal surrounding tissue.

How long will I be in the office each day for treatment?

Treatments generally take about 10-15 minutes total. (Simulation on the first day takes 30-45 minutes.)

How many treatments does it take?

It takes about 15- 20 total treatments, averaging 3 treatments a week, to complete therapy.

Here’s a step-by-step overview of what to expect. 

  1.  A biopsy is performed on a clinically suspicious lesion
  2. You will schedule a follow up appointment to review the pathology results and discuss treatment options. The 2 primary types of treatments are surgical (Mohs and excision) vs. IG-SRT.
  3. While you are deciding what option is best for you, our office will perform a VOB to identify the likely cost of the IG-SRT based on your specific health insurance policy.
  4. If  IG-SRT is your choice of procedure, a simulation (sim) appointment will be scheduled. You will sign consent forms and discuss expectations at this appointment. Photos, ultrasound images and treatment parameters are discussed with the dermatologist and areas of treatment are marked. This is about a 45 minute appointment.
  5. After your sim appointment treatment will start. At each visit your progress will be evaluated with ultrasound and treatment will be provided.
  6. Once your treatment of approximately 15-20 visits is complete you will schedule a 6 week follow up appointment. An ultrasound will be performed to ensure resolution of the skin cancer. In rare cases, a booster treatment protocol may be needed.
