What is Superficial Radiation Therapy?

Superficial radiation therapy (SRT) is a specialized form of radiation treatment primarily used for skin cancers and dermatological conditions, targeting only the surface layers of the skin. Unlike traditional radiation therapy, SRT utilizes low-energy radiation beams directed precisely at the affected skin area, making it non-invasive and relatively painless. It is commonly employed for treating basal cell carcinoma, squamous cell carcinoma, keloids, and dermatitis, particularly in areas where surgery may pose challenges or cosmetic concerns, such as the face, neck, and hands. SRT is often administered in outpatient settings, offering patients an effective alternative to surgery with minimal side effects and favorable cosmetic outcomes.

Why Use Superficial Radiation Therapy?

Superficial radiation therapy (SRT) is preferred for several reasons. Firstly, it’s non-invasive and relatively painless, making it suitable for patients who may not be candidates for surgery or prefer a less invasive option. Additionally, SRT precisely targets only the superficial layers of the skin, minimizing damage to surrounding healthy tissue and reducing the risk of scarring. It’s particularly beneficial for treating skin cancers and dermatological conditions in cosmetically sensitive areas like the face, neck, and hands, where surgical intervention may result in more noticeable scars or functional impairments. Furthermore, SRT can be performed in outpatient settings, offering convenience and minimizing disruptions to daily life for patients. Overall, SRT provides an effective and well-tolerated treatment option with favorable cosmetic outcomes for various skin conditions.
