Non-Surgical Skin Cancer, Keloid & Skin Treatment in Knoxville, TN

If surgery isn't the right fit for you — or a skin cancer or stubborn skin condition keeps coming back after the usual treatments — non-surgical radiation therapy may be an option worth understanding, in coordination with the dermatologist already caring for you.

Radiation therapy treats the skin without cutting. A precise, low-energy beam of X-rays releases its dose in the outer few millimeters of skin — right where a non-melanoma skin cancer or a stubborn benign lesion lives — and fades before it reaches the healthy tissue and structures underneath. There is no incision, no stitches, no anesthesia, and no recovery window. Each visit takes only a few minutes; you walk in, get treated, and go about your day.

This is our focus. Heelex is a dedicated radiation therapy clinic for skin cancers and benign skin conditions. Decades of published research support these uses. We accept Medicare and many major plans, and we verify your benefits before your first visit. We work alongside the dermatologist caring for you. Information for referring physicians →

How Radiation Treats Skin Cancer

Non-melanoma skin cancers — basal cell carcinoma and squamous cell carcinoma — grow from cells in the outer layers of the skin. Radiation therapy works by delivering targeted energy to those dividing cancer cells, damaging the DNA that lets them multiply. Cancer cells are far less able to repair that damage than the surrounding normal cells, so over a course of treatment the tumor is steadily eliminated while the healthy skin around it recovers.

The total dose is divided into many small treatments, called fractions, given on weekdays over several weeks. Splitting the dose this way is deliberate: it gives normal skin time to heal between sessions and produces a better cosmetic result than a single large dose would. The exact number of fractions, the energy used, and the size of the treated area are mapped to your specific lesion — its type, depth, and location — and finalized at your consultation. Nothing about the course is one-size-fits-all.

Not Every Skin Cancer Should Be Treated With Radiation

Surgery — including Mohs — is the standard of care for most non-melanoma skin cancers, and for many patients it is exactly the right choice. We say that plainly because it's true, and because the clinics worth trusting are the ones that also tell you when you don't need what they offer.

Radiation therapy is an established option for a specific group of patients: those who aren't good candidates for surgery, or who reasonably prefer to avoid it — lesions in cosmetically or functionally sensitive areas, patients on blood thinners, older or frail patients in whom wounds heal slowly, and people who simply want to avoid a scar. It is not the right tool for every skin cancer: melanoma is not treated with this modality, and large, deeply invasive, or aggressive-subtype tumors are usually better served by surgery.

So we review your pathology first. If radiation is a sound option for your case, we'll explain it honestly. And if it isn't — if your case is better suited to surgery, or still needs a biopsy or a diagnosis — we'll tell you, and make sure you get the right care instead of starting treatment here. For most patients that means staying in your own dermatologist's hands: we keep them in the loop and send you back to their care.

Working With Your Dermatologist

Your dermatologist is the expert in your skin — in spotting skin cancer, reading your pathology, and deciding the right plan for it. We don't change that, and we wouldn't want to. We don't diagnose skin cancer and we don't decide your treatment; your dermatologist does. We're here for the cases where they decide a non-surgical option is the better path for a particular patient.

And we have real respect for their work. Mohs surgery is meticulous, high-cure-rate medicine, and for many basal cell and squamous cell carcinomas it is exactly the right choice. We don't perform Mohs and we don't compete for surgical cases. We see ourselves as a resource for dermatologists, not a replacement for them: the patient stays theirs, we treat only the slice they refer, we keep them informed throughout, and we send the patient right back to their care.

Where radiation therapy fits is the appropriately selected, non-surgical-candidate patient — lesions on the face, ears, nose, eyelids, lips, or scalp; patients on anticoagulants; older patients in whom surgical wounds heal slowly; and those who, after talking it through with their dermatologist, would rather avoid a procedural scar. If that's not your situation, we'll say so and point you back to the right care.

For referring dermatologists: We'd welcome the chance to be a resource for the patients you'd rather not take to surgery — the frail, the anticoagulated, the sensitive-site lesions, the patients who decline excision. You keep the patient; we treat only what you send, document the course, and refer back to you. We don't perform Mohs and we don't compete for your surgical cases. See how referrals work →

What to Expect — From Consult to Last Session

We want you to know exactly what the experience is before you decide. Here's the full arc of treatment:

• Consultation and review. Our physician reviews your biopsy and pathology, examines the lesion, and confirms whether radiation is an appropriate choice for your case. We answer your questions and, if you're a candidate, walk you through the plan. If you're not, we tell you and direct you to the right care.
• Treatment mapping. Before treatment begins, we define the exact area to be treated and the dose plan tailored to your lesion's type, depth, and location. A small margin of normal-looking skin around the visible lesion is included, because skin cancers can extend slightly past their visible edge.
• The treatment sessions. You come in on weekdays for a series of short visits. Each session itself takes only a few minutes. You lie or sit comfortably; there is no anesthesia, no needles, and no sensation during the treatment itself — most patients feel nothing at all.
• Through the course. The treated skin gradually reacts — typically pinkness, then redness, sometimes mild peeling or crusting toward the end, much like a localized sunburn confined to the treated patch. We see you throughout and manage any reaction.
• Finishing and healing. After the last session the skin reaction peaks over a week or two and then heals. The cosmetic result continues to improve over the following weeks and months as the skin remodels.

Side Effects, Healing, and the Cosmetic Result

Because the dose is concentrated in the outer skin and divided into small fractions, side effects are local and limited to the treated area — there is no hair loss elsewhere, no nausea, and none of the whole-body effects people associate with chemotherapy. During the course, the treated patch reddens and may peel or crust, similar to a contained sunburn. This settles within a few weeks of finishing.

Longer term, the treated skin may end up slightly lighter or show fine changes in texture or small surface blood vessels. For lesions in cosmetically sensitive areas — the nose, lip, ear, or eyelid — avoiding an incision and reconstruction is often exactly why a patient and their dermatologist choose this path. We review the expected cosmetic outcome with you honestly before you begin, including the trade-offs, so there are no surprises.

Basal Cell Carcinoma (BCC) — Non-Surgical Treatment

Basal cell carcinoma is a malignant cancer of the basal keratinocytes and the most common cancer diagnosed in humans. It is malignant — never low-grade, never benign — and untreated lesions enlarge locally, eroding surrounding tissue and, on the face, the structures beneath it. BCC rarely spreads to distant sites, but it does not resolve on its own and is best treated early.

Radiation therapy is a well-established option for appropriately selected basal cell carcinomas, particularly nodular and other common forms on the face and head. For appropriately selected early basal cell carcinomas, published cure rates exceed 90%. The beam is concentrated at the lesion in the outer skin and is a sound non-surgical choice when surgery is undesirable or difficult — sensitive sites, anticoagulated or frail patients, or a patient who prefers to avoid an incision.

A typical BCC course at Heelex is 15 to 30 short weekday sessions, with each visit taking a few minutes. There is no cutting, no stitching, no anesthesia, and no recovery window. You walk in, get treated, and go about your day.

Squamous Cell Carcinoma (SCC) — Non-Surgical Treatment

Squamous cell carcinoma is the second most common skin cancer. It arises from the squamous keratinocytes of the upper skin and can develop from a precancer (actinic keratosis) or from carcinoma in situ (Bowen's disease) before becoming invasive. Caught early, it is highly treatable. For appropriately selected early squamous cell carcinomas, published cure rates exceed 90%.

Radiation therapy is a well-established non-surgical option for appropriately selected SCC presentations. The protocol mirrors the BCC course — a series of short weekday sessions, painless treatment, no incision or stitches. SCC on the lip, ear, scalp, and lower leg — locations where surgical reconstruction is technically challenging or where wound healing is unreliable — is where the non-surgical option most often meaningfully changes the conversation.

Actinic Keratosis and Precancerous Lesions

Actinic keratoses are rough, scaly patches caused by years of sun exposure. They are precancers — a portion can progress to squamous cell carcinoma over time — and most are managed well by a dermatologist with topical creams, cryotherapy, or field treatments. We don't displace any of that. In selected cases where those approaches have failed, can't be tolerated, or aren't suitable for a particular lesion, radiation therapy can be a targeted option, decided together with your dermatologist.

Skin Cancer Treatment for the Face — Without Scarring

Facial skin cancers — on the nose, the cheek, the eyelid, the lip, the ear, the temple — sit in cosmetically and functionally sensitive territory. Surgical excision and reconstruction in these areas is meticulous, high-cure-rate work, and for many patients it is exactly the right choice. For a patient who isn't a good surgical candidate, or who would prefer to avoid a procedure in a visible area, radiation therapy offers a non-surgical path: it treats the lesion in the outer skin with a tightly conformed low-energy beam that spares the underlying structures and the surrounding skin.

Non-Surgical Skin Cancer for Patients on Blood Thinners

Patients on Eliquis, warfarin, Plavix, Xarelto, or any chronic anticoagulant face a real complication with surgical skin-cancer excision: bleeding risk during the procedure and impaired wound healing after. The standard workaround is to bridge or pause the anticoagulant, which carries its own clotting risks for patients on blood thinners for atrial fibrillation, prior stroke, or pulmonary embolism history. Radiation therapy sidesteps the entire trade-off. There is no incision, no bleeding, no need to interrupt your anticoagulation. The treatment goes ahead while you remain on your prescribed regimen.

Skin Cancer Treatment for Seniors

For patients in their eighties and nineties, the questions around skin cancer treatment are different. Surgical wounds heal more slowly. General anesthesia carries higher risk. Lower-leg lesions in older patients can become chronic, non-healing wounds that linger for months. Radiation therapy is gentle, painless, requires no anesthesia, and leaves no surgical wound to heal. For many of our oldest patients, it is the treatment that finally makes sense — an option that fits the realities of their other health considerations.

Recurrent Skin Cancer Treatment

A non-melanoma skin cancer that has recurred after a prior surgical excision or a previous Mohs procedure is a different clinical situation than a first presentation. The local tissue has already been altered. Margins are harder to read. Re-excision often means a larger procedure with a larger scar. Radiation therapy can be well-suited to the recurrent setting — it delivers treatment directly to the lesion without re-entering the surgical field, and the team confirms response over the course of treatment. Whether radiation or further surgery is the better choice depends on the case, and we make that call together with your dermatologist.

After Treatment — Follow-Up and Skin Surveillance

Finishing treatment is not the end of your skin care. Anyone who has had one non-melanoma skin cancer is at higher risk of developing another, somewhere else, over the years that follow. That ongoing skin surveillance belongs with your dermatologist — the regular full-skin checks that catch the next lesion early. We document your treated lesion and its response and send that record back to your dermatologist, so your skin checks continue seamlessly in the hands of the doctor who knows your history.

Keloid Prevention After Surgery

For patients with a history of forming keloids, the most important conversation happens before the next surgical procedure — not after. Post-excision low-dose radiation therapy is the most evidence-supported prophylactic approach for reducing the likelihood of keloid recurrence. It is given as a short course in the 24 to 48 hours after the excision, and the course is individualized at consultation. If you are scheduled for a keloid excision, an earlobe procedure after piercing-related keloid formation, or any surgery where you have a personal history of keloid response, schedule the consult before the surgical date. This is a service we provide hand-in-hand with the surgeon performing your excision.

Warts That Resist Standard Treatment

Plantar warts, common warts, and periungual (around-the-nail) warts are caused by human papillomavirus (HPV). Standard treatments — cryotherapy, salicylic acid, laser, surgical paring — clear the surface tissue, but if even a small reservoir of HPV-infected cells survives in the deeper skin layer, the wart returns. Many patients cycle through months or years of repeat treatments without lasting clearance.

Low-dose radiation therapy targets HPV-infected cells directly. The low-energy beam reaches the depth of the wart and damages viral DNA in infected keratinocytes, while leaving healthy deeper tissue untouched. No cutting, no burning, no chemical irritation, no scar.

This approach is particularly valuable for:

• Plantar warts that have failed multiple rounds of cryotherapy
• Periungual warts where surgical or laser destruction risks the nail matrix
• Patients with diabetes or peripheral vascular disease, where foot wounds heal poorly and cryogenic injury can become a serious problem
• Older patients and anyone wanting a painless, non-destructive option

A typical wart course is 3 to 7 short sessions over consecutive weekdays. Each session takes a few minutes. Most patients feel nothing during treatment.

Localized Psoriasis That Hasn't Cleared

Psoriasis is a chronic autoimmune skin condition driven by overactive T-cells that accelerate skin-cell turnover, producing the thick, scaly, inflamed plaques patients know well. Most patients are managed effectively with topical steroids, vitamin D analogs, phototherapy, or systemic biologics. But some plaques — particularly on the scalp, hands, feet, elbows, and knees — resist every line of treatment and remain symptomatic for years.

Low-dose radiation therapy is a targeted, localized option for these resistant plaques. The low-energy beam calms the rapidly dividing skin cells driving the plaque and reduces the local inflammatory response, without affecting the rest of the body and without the systemic side effects of biologics or long-term steroid use.

This approach is particularly useful when:

• A single plaque or small area has failed topicals, phototherapy, and systemic therapy
• Systemic biologics are contraindicated or have caused side effects
• A symptomatic plaque is in a location that interferes with function (palms, soles) or is cosmetically distressing
• The patient prefers a localized, drug-free option

A typical course is 6 to 10 short sessions over consecutive weekdays. Most patients see meaningful clearance within weeks of finishing treatment.

Cost and Insurance

Radiation therapy for non-melanoma skin cancer is a covered benefit under Medicare and most major plans for appropriate indications. We verify your specific coverage and out-of-pocket responsibility before any treatment begins, so you know where you stand before you start. If you have questions about coverage, our team will walk you through it.

Note: melanoma is not treated with this modality, and very large or aggressive-subtype tumors may be better served by surgery — we review your pathology and tell you honestly whether you're a candidate. Read more about our dedicated keloid treatment program →
