SRT is a skin cancer therapy that uses low doses of radiation to destroy nonmelanoma cancer cells in the upper layers of the skin. This treatment is an effective option for keloid scar removal and prevention after scar surgery. Orlando Dermatology Center specializes in the use of high-frequency ultrasound imaging and SRT to treat skin cancer. The dermatology team uses modern equipment like SRT-100™ technology to provide excellent cure rates and the best possible cosmetic outcome. The team manages all facets of skin cancer treatment, including early identification and diagnosis, SRT procedures, ultrasound monitoring, and follow-up care. High Frequency Ultrasound for Measuring and Monitoring Skin Cancers Our clinic uses Superficial Radiation Therapy (SRT) to safely and effectively treat non-melanoma skin cancers. We enhance precision by using Episcan high-frequency ultrasound to accurately measure and monitor skin cancer depth throughout the treatment, ensuring optimal radiation doses tailored to each patient's unique condition. This integrated approach allows for real-time adjustments, reducing the risk of recurrence and minimizing damage to healthy surrounding tissue, resulting in improved outcomes and better patient comfort. What can I expect during superficial radiation therapy? The SRT-100 technology delivers low-dose radiation into the skin to destroy cancerous cells without harming healthy tissue nearby. At Orlando Dermatology Center, the noninvasive treatment is available on an outpatient basis, so you can go home soon after your procedure. During your treatment, you lie on an exam table and the team marks the treatment area with special ink. They place a lead shield over healthy tissue in the area to protect it from radiation. Using SRT-100 technology, the providers direct a beam of low-energy radiation into the top layers of your skin to destroy cancer cells. Your dermatologist carefully calibrates the dose of radiation you receive throughout the 15 to 30-minute treatment. The precision of the technology ensures radiation targets only the cancerous cells to prevent damage to healthy tissue. The team also uses high-frequency ultrasound imaging for accurate cancer measurement over the course of your treatment. If you’re undergoing SRT after keloid scar removal surgery, the team directs the beams of radiation into the treatment area to eliminate cells that form keloid scars. What follow-up care do I need after superficial radiation therapy? Orlando Dermatology Center’s board-certified dermatologists provide comprehensive after-care following SRT procedures for skin cancer and keloid scars. After SRT, you can expect to return to the office for a skin evaluation. The team uses ultrasound imaging to ensure treatment destroys all cancerous cells or cells that cause keloid scars. They also confirm no new skin abnormalities are present. The consistent care the team provides improves your overall outcome and protects the long-term health of your skin.
