Is There an Alternative to Surgery or Mohs for My Skin Cancer?

The short answer: Yes.

If you’ve been diagnosed with a common form of skin cancer — like basal cell carcinoma (BCC) or squamous cell carcinoma (SCC) — you may have been told that Mohs micrographic surgery is the “gold standard” treatment. And it is — especially for high-risk or hard-to-treat lesions. Mohs offers precision by removing cancer layer by layer and examining each margin in real-time, which results in cure rates over 97% and the ability to spare as much healthy tissue as possible with often times excellent cosmetic outcomes. 

But what if you’re not a good candidate for surgery — or simply prefer to avoid it?

That’s where radiation therapy — specifically superficial radiation therapy (SRT) — comes in. This non-invasive treatment uses low-energy electron or photon beams that only go skin-deep, targeting the cancer without affecting deeper tissues or organs. Radiation has been used for decades with excellent results and is an especially appealing option for:

• Patients with early-stage BCC or SCC (generally <1–3 cm in size)
• Tumors in highly visible or delicate areas like the face, nose, eyelids, ears, or lips
• Those who may not be ideal surgical candidates due to age, medical conditions, or healing concerns
• Patients seeking better cosmetic outcomes without surgical scars or reconstruction in sensitive or visible areas
• Patients who have had many surgeries and want to opt for a non-invasive option

How Effective Is Radiation Compared to Surgery?

Several large studies and clinical guidelines — including those from the American Society for Radiation Oncology (ASTRO) — support radiation as an effective and proven alternative. Cure and control rates are typically >90–95%, which is comparable to surgical excision in many cases.

However, success depends on choosing the right patients and tumors. Radiation oncologists carefully evaluate the size, depth, location, and risk features of the cancer to determine whether radiation is a suitable substitute for surgery.

What’s the Treatment Like?

Radiation doesn’t require cutting or anesthesia. Instead, it’s usually delivered over several short sessions, typically 5 to 30 treatments, depending on tumor size and location. Each session lasts about 5–10 minutes, and you can go about your normal life during treatment. You also won’t be radioactive — nothing stays in your body.

For visible areas like the scalp, face, or neck, longer treatment courses may be used to help minimize discoloration, scarring, or textural changes. Most patients experience only mild side effects like skin redness or fatigue, which resolve within 1–3 weeks. Skincare during and after treatment is simple and effective — I often recommend calendula oil, Aquaphor, and triple paste with zinc, a regimen that’s produced outstanding cosmetic results (credit to a wonderful beautician collaborator). In the long-run, tree-nut oils (e.g., coconut oil) or vitamin E creams 1-2 times per day keep the treated area of skin healthy, and gentle 30-60 second daily massage of the treated skin may be recommended to prevent any mild firmness over time depending on the location treated. 

So Which One Is Right for Me — Radiation or Surgery?

Both options are tools in the toolbox. Surgery is quick, typically done in one day, and offers the advantage of immediate pathology confirmation and has a 97% control rate. But it may involve cutting, scarring, or even grafting — especially in cosmetically sensitive areas. Radiation is non-invasive, offers excellent results with a >90-95% control rate, and preserves form and function — but requires more time.

Ultimately, the best choice depends on your cancer’s features, your health, and your personal goals and preferences. It’s a decision best made together — with your dermatologist and care team.
