Treatment is done right in the dermatology office over the course of a few weeks using an advanced Image-Guided SRT machine.

See what to expect with treatment

GentleCure (Image-Guided SRT) is designed to treat skin cancer without the discomfort and cosmetic issues often associated with surgery. There is no cutting, surgical scarring, or need for reconstructive surgery, and you can maintain your normal daily activities throughout treatment.

Using an imaging wand, we will look at a detailed image of your cancer on screen. You can see the image yourself from the comfort of the chair. We will use that image to measure the size and shape of the tumor, calculate the precise dose of treatment, and define the treatment area.

GentleCure (Image-Guided SRT) has a proven track record that is backed by science and clinical research

At the Derm Institute of West Michigan, our team of dermatologists reviewed the published research and here is what we found:


Yu L, et al. Oncol Ther.
Retrospective chart review evaluating LC rates of 1632 patients with 2917 stage 0-II carcinomas

  • In 2021, chart reviews were conducted for 1632 patients who had Image-Guided SRT to treat one or more early-stage basal or squamous cell skin cancers. Of those patients, 2917 skin cancers in total were treated. The results showed a 99.3% cure rate with Image-Guided SRT, which we believe to be equal to or better than Mohs surgery.
  • In 2022 and 2023, additional studies were published that showed the efficacy and safety of Image-Guided SRT to be superior to non-image-guided forms of radiation therapy across skin cancer types—confirming its use as a first-line treatment for basal and squamous cell skin cancers. This means doctors and patients should give equal consideration to Mohs surgery and surgery-free Image-Guided SRT as standards of care.

Why we chose to offer GentleCure (Image-Guided SRT)

There are several different radiation-based treatments available for skin cancer. But the safety, cure rates, and cosmetic outcomes vary based on the treatment technology and clinical protocols used. We chose GentleCure (Image-Guided SRT) because it is the only skin cancer treatment with advanced imaging that lets us see and measure the cancer and adapt the dose to precisely what you need at each stage of treatment. It has also been shown to be the safest and most effective of all radiation-based treatments for skin cancer with superior cosmetic results.

If you are considering radiation therapy to treat your skin cancer, make sure you are getting GentleCure (Image-Guided SRT) with adaptive radiotherapy protocols. It’s the safe, effective, and gentle way to treat skin cancer using the most advanced treatment technology available today.

Treatment results – Seeing is believing!

No two cases of skin cancer are the same, so treatment results may vary from patient to patient. But the pictures below are typical of the results seen by patients who have received GentleCure (Image-Guided SRT).



Patient with basal cell skin cancer on the top of the ear before treatment with GentleCure (Image-Guided SRT). You can see the cancer on the skin. The ultrasound image clearly defines the skin cancer under the skin, indicating the full depth, width, and breadth of the cancer.



About half-way through treatment with GentleCure (Image-Guided SRT), you can see the cancer reducing in size on the outside of the skin. The ultrasound image shows that the cancer under the skin has also been reduced.



At the two-week follow-up visit after treatment was completed, the outside of the ear shows no signs of cancer. The ultrasound image shows that GentleCure (Image-Guided SRT) continued to eliminate the cancer. At the 30-week follow-up appointment, the ultrasound image showed no signs of cancer.

GentleCure (Image-Guided SRT) is covered by Medicare and most health insurance plans

With most insurance plans, you may have to pay some out-of-pocket cost. That cost will depend on your specific health plan coverage and co-pay policy. Before you commit to a treatment option, we will work with your insurance plan to determine the potential cost to you, so you can make an informed treatment decision. If you are worried about affording treatment, let us know and we can discuss our financial assistance options.

Side effects and cosmetic results

When X-ray energy is used to kill cancer cells, your body will replace the dead cancer cells with healthy tissue over time. There is no surgical scarring and no need for reconstructive surgery. There is, however, a small risk of skin atrophy (thinning of the skin) and pigment changes (changes in the color of the skin) at the treatment site. Other potential side effects may include skin inflammation with redness and swelling at the treatment site. Topical creams or ointments can be used over the course of treatment to minimize these side effects, and the side effects usually go away 2 to 6 weeks after treatment is complete. There is also a risk of alopecia (hair loss) in the treated area only.

In the 7 years that patients have been receiving GentleCure (Image-Guided SRT), there have been NO reported cases of secondary skin cancers occuring as a result of treatment.
