SRT: Superficial Radiation Therapy

What Skin Cancer Treatment Is Right For You?

What is SRT?

  • Musick Dermatology is proud to offer Image-Guided Superficial Radiotherapy (IG-SRT), which is called SRT for short. SRT can deliver precise doses of radiation into the skin by effectively targeting tissue only within approximately 3 millimeters of the skin’s surface.
  • SRT is an alternative to invasive surgery, such as the MOHS Surgery, to destroy non-melanoma Skin Cancers and keloids with a 99.3% cure rate !!
  • SRT uses low energies and doses of radiation to treat Squamous Cell Cancer and Basal Cell Cancer just below the skin surface.
  • Due to the low energies (kilovoltage), skin reactions are typically mild and very small.
  • Traditional radiation is the opposite, in which it delivers massive amounts of energy (megavoltage) that penetrate deep into the body which can cause more skin reactions.

Candidates of SRT

  • SRT is a great option for those who DO NOT WANT SURGERY, or are poor candidates for surgery due to health reasons.
  • SRT is an impressive option for patients with Basal Cell Carcinoma (BCCs) and Squamous Cell Carcinomas (SCCs).
  • SRT is an excellent choice for those who want to stay active and have no downtime.
  • SRT has great potential for treating patients whose cancer exists in areas that are difficult to access for surgical removal.

Treatment, Follow up and Results


  • SRT Treatments generally take about 10-15 minutes, after the first visit (simulation) which can take up to 45 minutes.
  • The number of SRT Treatments can vary, averaging 3 treatments a week, for about 7 weeks to complete therapy.


  • 2 weeks following the last treatment the patient will come in to the SRT room for a final ultrasound.  This depth measurements will be highly decreased when compared to the simulation day.
  • Dr. Musick will see the patient for a skin check of the treatment area and to answer any patient questions.
  • Even though treatments are complete, radiation will continue working for up to four weeks after the patient’s last day.  


  • SRT offers 95% or greater cure rate of BCC and SCC.
  • If the patient experiences a reoccurrence in the same area,  they may not be treated with radiation again.
