IG-SRT

Biltmore Dermatology Terre Haute & Vincennes Image-Guided Superficial Radiation Therapy (IG-SRT)

Not every skin cancer needs a scalpel. Image-guided Superficial Radiation Therapy (IG-SRT) offers a non-invasive, non-surgical treatment option for certain types of early-stage skin cancers. At Biltmore Dermatology, we use IG-SRT to provide safe, effective care — without pain, needles, cutting, stitches, or surgical downtime.

What Is IG-SRT?

IG-SRT combines high-frequency ultrasound imaging with precisely targeted superficial radiation to treat skin cancers without surgery. The imaging allows us to:

• Map the exact size, shape, and depth of the skin cancer
• Target only the cancerous tissue
• Minimize exposure to healthy surrounding skin

The radiation is shallow — it only penetrates the surface layers of the skin — making it ideal for Basal Cell Carcinoma and Squamous Cell Carcinoma detected early.

Benefits of IG-SRT

• Non-surgical: No cutting, no stitches, no anesthesia
• Painless: Most patients report little to no discomfort during or after treatment
• Cosmetic preservation: Especially valuable for cancers on the face, scalp, nose, ears, and hands
• Outpatient treatment: Done right here in our Terre Haute and Vincennes offices
• Minimal downtime: No wound care, bandaging, or significant activity restrictions
• High cure rates: Comparable to surgical options for properly selected cases

IG-SRT offers a modern way to treat skin cancer — without the scars surgery can leave behind.

Who Is a Candidate for IG-SRT?

IG-SRT is often an excellent option for patients with:

• Early-stage Basal Cell Carcinoma or Squamous Cell Carcinoma
• Lesions in cosmetically sensitive areas (face, ears, scalp, neck, hands)
• Medical conditions that make surgery risky (bleeding disorders, poor healing ability)
• Personal preference for non-surgical treatment

Not every skin cancer qualifies — but for those that do, IG-SRT offers a powerful, low-impact alternative.

What to Expect During IG-SRT Treatment

• Imaging first: A quick, painless ultrasound maps the cancer
• Precise planning: Radiation settings are tailored to your specific tumor
• Treatment sessions: Usually 2–4 sessions per week over several weeks (depending on tumor size and depth)
• Short appointments: Each session takes only a few minutes
• No sedation needed: You can drive yourself home after each visit
• Minimal side effects: Mild redness or dryness at the treatment site is common; serious reactions are rare

Throughout your treatment, our team monitors your progress carefully, adjusting as needed to ensure the best outcome.
