What is SRT-100


The SRT-100 is a state-of-the-art Superficial Radiation Therapy (SRT) system designed for the non-invasive treatment of non-melanoma skin cancers, such as basal cell carcinoma and squamous cell carcinoma, as well as keloid scars. Unlike traditional surgical methods, SRT-100 delivers targeted low-dose radiation to the skin's surface, effectively treating cancerous cells while preserving healthy tissue beneath.


How It Works

The SRT-100 employs image-guided technology, often using ultrasound, to precisely locate and measure the tumor. A specialized applicator cone is then positioned over the lesion, delivering focused X-ray energy to the targeted area. This method ensures that only the cancerous tissue is treated, minimizing exposure to surrounding healthy skin. 


Key Benefits

  • High Cure Rates: Achieves cure rates of over 99%, comparable to or exceeding those of Mohs surgery.
  • Non-Surgical: No incisions, stitches, or anesthesia required.
  • Minimal Discomfort: The procedure is virtually painless, with no bleeding or scarring.
  • Quick Recovery: Patients can resume daily activities immediately, with no downtime or lifestyle restrictions.
  • Cosmetic Preservation: Ideal for treating lesions on sensitive areas like the face, ears, and neck, maintaining aesthetic appearance.
  • No Need for Reconstructive Surgery: Eliminates the need for post-treatment reconstructive procedures.
  • Safe for Various Health Conditions: Suitable for patients on blood thinners, those with pacemakers, diabetes, or compromised immune systems.


Treatment Overview

  • Session Duration: Each treatment typically lasts about 1 minute.
  • Frequency: Administered several times a week, with the total number of sessions determined by the treating physician.
  • Post-Treatment Care: Patients may experience mild skin redness, which usually subsides within a few days.

Ideal Candidates

The SRT-100 is particularly beneficial for patients who:

  • Have skin cancers located in cosmetically sensitive areas.
  • Are seeking a non-invasive treatment option.
  • Wish to avoid surgical procedures and potential scarring.
  • Have medical conditions that complicate surgical treatments.
