Radiation is a very important tool in the fight against skin cancer. When radiation interacts with a cancerous cell, it alters the cell’s DNA (or genetic make-up) and its ability to reproduce, which ultimately leads to cell death in the cancerous tumor. Superficial Radiotherapy (SRT) is a device that delivers a very superficial form of radiation. This treatment is confined to the skin. It does not affect other organs.
What is SRT?
SRT is a low-energy radiotherapy that penetrates only a short distance below the surface of the skin, is a highly effective, painless, and cosmetically attractive alternative to surgery in selected cancers and patient populations. The SRT-100™ is the new and most advanced choice for superficial radiotherapy available today, is painless, and very similar to having an x-ray.
Why Choose SRT?
The SRT-100™ treats non-melanoma skin cancers that are found on the surface of the skin. It can be used for lesions on the arms, legs, back and trunk, but it is especially well suited for skin cancers of the head and neck regions—the fold in the nose, eyelids, lips, corner of the mouth, and the lining of the ear—that would otherwise lead to a less than desirable cosmetic outcome. SRT is also a great treatment option for patients who are considered high risk for surgical procedures. This form of treatment has been successfully treating skin cancer for a hundred years. The cure rate is the same as surgery. No biopsy needed after treatment.
What is the Difference Between SRT and Mohs Surgery?
The cure rate is the same for both treatment options. SRT and Mohs Surgery are close to perfect when it comes to curing skin cancer. Mohs surgery is a one-day event, which appeals to people who want to get it done and over with. It does require the removal of the cancerous tissue through surgery. SRT requires about 12 visits over 4 weeks, but the visits are a few minutes each. SRT appeals to people who want the cancer cured without needles or cutting, and gives them a better cosmetic outcome. It does require multiple short visits to our office.
What to Expect
The SRT procedure is non-surgical and does not require the use of anesthetics. You will be required to attend multiple sessions, depending on your doctor’s recommendations. Tell your doctor about medications you are taking and continue them unless your physician tells you otherwise. The X-ray will be directed toward the lesion by placing an applicator cone over the treated area. Once the treatment begins, it will take approximately 90 seconds to deliver the therapy. The treatment is painless, but you will notice skin redness by the end of the first week’s treatment. Post-treatment, the skin will form a protective scab. The new, healthy skin will develop underneath it.
