Most people have never heard of IG-SRT until it’s mentioned during a dermatology appointment.
Usually that is because it isn’t the kind of treatment you come across unless skin cancer becomes part of the conversation. A biopsy comes back, your dermatologist starts discussing treatment options, and suddenly you’re trying to learn an entirely new set of medical terms. Surgery makes sense because most people already have a general idea of what surgery involves. Radiation sounds familiar too, but not when it’s being used to treat a small area of skin instead of a tumor deep inside the body.
It’s easy to assume there’s one standard treatment for every skin cancer diagnosis. In reality, dermatologists choose from several options depending on the type of cancer, where it’s located, how large it is, a patient’s overall health, and what kind of result they’re trying to achieve. Surgery remains the right answer for many patients, but it isn’t the only answer.
That’s where Image-Guided Superficial Radiation Therapy, usually shortened to IG-SRT, enters the discussion.
Over the past several years, more dermatology practices have started offering this technology because it gives carefully selected patients another way to treat certain non-melanoma skin cancers without making a surgical incision. If you’ve been researching treatment options in Greeley or you’ve recently been told you’re a candidate for IG-SRT, understanding why your dermatologist recommended it makes the entire conversation much easier to follow.
Why Dermatologists Don’t Recommend the Same Treatment for Everyone
One thing I’ve learned after talking with friends and family members who have dealt with skin cancer is that two people can receive the same diagnosis and leave their appointments with completely different treatment plans.
That isn’t because one dermatologist is more aggressive than another. It’s because skin cancer is rarely as simple as the biopsy report alone.
A small basal cell carcinoma on someone’s shoulder may be treated differently than one growing near the corner of an eye. Someone in their forties with excellent overall health may have different priorities than a patient in their eighties who takes blood thinners and has several other medical conditions to consider. Even a person’s work can influence the conversation. If someone spends every day outside interacting with customers, preserving the appearance of the treatment area may carry more weight than it would in another situation.
Dermatology has become increasingly personalized over the past decade. Instead of asking, “What’s the standard treatment?” physicians are more likely to ask, “What’s the best treatment for this patient?”
IG-SRT is one of the reasons those conversations have become more flexible.
What Is IG-SRT?
Image-Guided Superficial Radiation Therapy combines two technologies that work together throughout treatment.
The first is high-frequency ultrasound. Before each treatment, ultrasound allows the provider to see the depth and boundaries of the skin cancer beneath the surface. Rather than estimating where the cancer begins and ends, they can evaluate the area using real-time imaging.
The second component is superficial radiation therapy. Unlike the radiation people associate with many internal cancers, superficial radiation travels only a short distance into the skin. It is designed to target skin cancers near the surface while minimizing exposure to deeper tissues. Those ultrasound images become important because treatment can be adjusted as the skin cancer responds over time. Rather than relying solely on what is visible from the outside, providers can monitor changes beneath the skin throughout the treatment process.
For patients, the appointments themselves are usually straightforward. There isn’t an operating room, stitches, or a recovery period associated with surgery. Treatment is delivered over a series of visits instead of everything happening in a single day, which is one of the biggest differences patients notice.
Who Is Usually a Good Candidate?
IG-SRT isn’t intended to replace every other form of skin cancer treatment. Dermatologists have several highly effective options available, and the best choice depends on the details of each individual case rather than a single diagnosis.
Many candidates have basal cell carcinoma or squamous cell carcinoma that has been diagnosed early and remains confined to the skin. Others have medical conditions that make surgery more complicated or increase the likelihood of bleeding, delayed healing, or other surgical risks. Some patients have already undergone several skin cancer surgeries over the years and want to explore another evidence-based treatment for a newly diagnosed lesion.
The location of the skin cancer also becomes part of the discussion. Lesions developing on the nose, ears, lips, eyelids, or other cosmetically sensitive areas deserve careful planning because even small differences in tissue removal can influence both appearance and function. While surgery remains an excellent choice in many of these situations, IG-SRT may also be considered for appropriately selected patients after a thorough evaluation.
Personal preferences play a role as well.
Some patients feel more comfortable completing treatment through a series of office visits instead of having a surgical procedure. Others appreciate avoiding stitches because of work, travel, or other responsibilities already on their schedule. Those practical considerations don’t outweigh medical judgment, but they do become part of the conversation once a dermatologist determines that more than one treatment approach could provide a successful outcome.
Rather than following a checklist, dermatologists consider the diagnosis, the location of the cancer, a patient’s overall health, previous treatment history, and long-term goals before making a recommendation. That individualized approach helps ensure the treatment plan fits both the skin cancer and the person receiving care.
Why Patients Sometimes Choose IG-SRT
When people first hear the word “radiation,” they sometimes picture lengthy cancer treatments that leave patients exhausted.
IG-SRT doesn’t resemble that experience.
Treatment sessions are relatively brief, patients remain awake throughout the appointment, and most people return to their normal routines afterward. Because there isn’t an incision, patients don’t have stitches to care for or surgical restrictions while the treatment course is underway.
That doesn’t automatically make it the better choice however.
Some patients prefer completing treatment during a series of shorter office visits instead of having surgery. Others appreciate avoiding an incision in a cosmetically sensitive location. For another patient, surgery may still provide the most appropriate treatment because of the type of skin cancer, its location, or other medical considerations.
Those conversations are exactly why an experienced dermatology team spends time discussing multiple options rather than assuming every patient values the same outcome.
What Treatment Looks Like
One of the biggest differences between IG-SRT and surgery is the timeline.
Mohs surgery or a standard excision usually happens in a single appointment. IG-SRT is completed through a series of treatments spread over several weeks. The exact number of visits depends on the type of skin cancer, its size, and the treatment plan your dermatologist develops after reviewing your biopsy and imaging.
Patients are usually surprised by how ordinary those appointments feel. Most visits are fairly short, and once treatment is finished for the day, people typically head back to work, run errands, or continue with whatever they had planned. There isn’t a surgical incision that needs to heal, and there are no sutures to remove later. Instead, your dermatologist follows the skin’s response throughout treatment, using ultrasound to monitor changes beneath the surface as the cancer responds.
Because the process happens gradually, patients have opportunities to ask questions along the way. If the treatment area becomes irritated, or if something doesn’t look the way they expected, those concerns can be addressed during one of the scheduled visits rather than waiting weeks for a follow-up appointment.
Side Effects and Recovery
People naturally want to know what they’ll look and feel like after treatment.
The answer depends on several factors, including where the skin cancer is located, how large it is, and how an individual’s skin responds. Most patients experience some redness or irritation within the treatment area, similar to a mild sunburn. As treatment continues, the skin may become dry, flaky, darker, or more sensitive before gradually improving after the final session.
Healing isn’t immediate because radiation continues affecting the treated cells even after appointments have ended. The skin keeps changing over the following weeks, and your dermatologist will continue monitoring that progress during follow-up visits.
One thing worth remembering is that skin heals at its own pace. Two people receiving treatment for similar skin cancers can have noticeably different recoveries. Age, overall health, medications, and the location of the lesion all influence how quickly the skin settles down.
Most patients find that recovery fits into everyday life without requiring significant changes to their routine, though following your dermatologist’s wound care and sun protection recommendations remains an important part of achieving the best long-term result.
Follow-Up Doesn’t End After Treatment
Finishing treatment isn’t the end of the story for most people diagnosed with skin cancer.
Once you’ve had one basal cell carcinoma or squamous cell carcinoma, the likelihood of developing another skin cancer later in life increases. That isn’t necessarily because the first treatment failed. More commonly, it reflects years or decades of cumulative ultraviolet exposure that affected more than one area of skin.
Dermatologists think in terms of long-term surveillance.
Routine skin examinations become part of ongoing healthcare in much the same way dental cleanings or annual physicals do. During those appointments, your provider isn’t only looking at the area that received treatment. They’re evaluating your skin as a whole, watching for new lesions or subtle changes that deserve a closer look.
Living in Northern Colorado reinforces that habit. People here spend a tremendous amount of time outside. Gardening, cycling, golf, youth sports, hiking, ranch work, construction, and countless other activities mean the skin continues accumulating ultraviolet exposure long after treatment has finished. Regular examinations help catch future concerns while they’re still small and highly treatable.
Questions Worth Asking
Most patients leave their consultation feeling better than when they walked in because they finally have answers instead of internet search results.
Before beginning treatment, it’s helpful to understand why IG-SRT was recommended for your specific diagnosis. Asking about alternative treatments, expected cure rates, the number of appointments, possible side effects, follow-up care, and how the treatment area is expected to heal gives you a much clearer picture of what the next several weeks will look like.
Those conversations are rarely rushed.
Every skin cancer behaves a little differently, and every patient brings different priorities into the appointment. Someone may be focused on minimizing scarring because the lesion is on the face. Another patient may be more concerned about avoiding surgery because of other health conditions. Those details help shape the treatment discussion.
The best consultations usually feel less like a lecture and more like a conversation.
Finding Skin Cancer Care in Greeley
Dermatology has changed considerably over the last decade. Physicians now have more tools available than they once did, and that allows treatment plans to be tailored more closely to each patient’s diagnosis, overall health, and personal preferences.
For many people, the hardest part of a skin cancer diagnosis is the uncertainty that follows. Learning what the diagnosis means, understanding why a particular treatment was recommended, and knowing what to expect over the coming weeks tends to replace much of that uncertainty with a clear plan.
IG-SRT won’t be the right recommendation for every patient, and it isn’t intended to be. It’s one of several effective treatment options available for certain non-melanoma skin cancers. If your dermatologist has suggested it, asking questions and understanding the reasoning behind that recommendation is one of the most valuable parts of the entire process.
