Superficial Radiation Therapy (SRT)
Focused radiation targeting lesions close to the skin surface—commonly used for treating skin cancers and superficial tumors with specialized beam profiles.
What is Superficial Radiation Therapy?
Superficial Radiation Therapy (SRT) is a specialized form of radiation treatment designed to effectively treat cancers and lesions located at or just below the surface of the skin. Unlike deeper-penetrating radiation therapies, SRT delivers low-energy X-rays that concentrate their therapeutic effect on shallow tissue, making it ideal for non-melanoma skin cancers and other surface-level conditions.
How It Works
Targeted Surface Treatment
Using a specially calibrated machine, SRT emits low-penetration beams that focus directly on the skin lesion or tumor. This ensures maximum treatment at the skin level with minimal radiation absorbed by deeper tissues.
No Incisions or Anesthesia
SRT is a completely non-invasive treatment that requires no surgery, no cutting, and no sedation. Treatments are quick and generally well-tolerated.
Custom Beam Shaping
Radiation is tailored to match the size, shape, and depth of the lesion using custom applicators and shielding—providing precise coverage with minimal effect on surrounding skin.
Benefits of SRT
Ideal for Skin Cancers
Highly effective for basal cell carcinoma, squamous cell carcinoma, and certain other surface-level tumors.
Cosmetic Preservation
Helps preserve skin appearance and structure—particularly beneficial for visible or sensitive areas such as the face, ears, scalp, or hands.
Painless & Convenient
Most sessions last only a few minutes, with minimal discomfort and little to no downtime.
Alternative to Surgery
Especially helpful for patients who are not good candidates for surgical excision due to medical conditions, age, or location of the tumor.
Common Uses for SRT
SRT is often recommended for:
Non-melanoma skin cancers
Skin lesions or tumors
Elderly or surgery-averse patients
Recurrent skin cancers
Sensitive or cosmetically important areas
What to Expect During Treatment
Initial Consultation & Mapping
Your radiation oncologist will evaluate your condition and determine if SRT is appropriate. Imaging or measurements may be taken to plan treatment.
Treatment Sessions
Most patients receive a series of short, painless treatments over several weeks. The exact course depends on your diagnosis and lesion characteristics.
Aftercare
Treated skin may appear red or irritated, similar to a mild sunburn. Our team provides care instructions and follow-up to ensure proper healing.

Other Services We Offer
Interested in exploring other precision-focused radiation therapies?
Intensity‑Modulated Radiation Therapy (IMRT)
Advanced radiation treatment designed to target tumors with precision while protecting healthy tissue.
Surface-Guided Radiation Therapy (SGRT)
Uses 3D camera systems to monitor patient surface motion in real-time. SGRT enhances accuracy and safety by automatically pausing treatment if movement exceeds designated thresholds.
Image-Guided Radiation Therapy (IGRT)
Utilizes advanced imaging (e.g., CT, MRI, PET) before and during treatment to ensure radiation targets the exact tumor location, reducing margins and improving accuracy.
