Choosing the Right Skin-Cancer Treatment: Surgery, Topicals, Radiation or Immunotherapy?
Finding out you have skin cancer can be overwhelming. But understanding your treatment options—and how dermatologists decide what’s best—can help you feel more in control. Whether it’s a small lesion on your face or a deeper tumor on your back, the treatment you receive depends on several key factors: the type of skin cancer, how advanced it is, and where it’s located.
Let’s break down the most common treatments—surgery, topicals, radiation, and immunotherapy—and explain when each might be the right choice.
1. The Big Three: Type, Stage, and Location
Before choosing a treatment, dermatologists evaluate:
-
Type: Is it basal cell carcinoma (BCC), squamous cell carcinoma (SCC), or melanoma? Each behaves differently.
-
Stage: How deep or widespread is the cancer? Early-stage lesions may need only topical treatment, while more invasive ones might require surgery or systemic therapy.
-
Location: A spot on the nose demands more precision than one on the shoulder due to cosmetic and functional concerns.
Understanding these three elements helps guide every treatment decision.
2. Surgical Treatments
Excision
This is one of the most common and effective treatments for BCC and SCC. The surgeon removes the cancer along with a small margin of surrounding healthy tissue. It’s straightforward, fast, and typically curative.
Mohs Surgery
Mohs is the gold standard for high-risk or facial skin cancers. It’s done in stages while you wait, with each layer examined under a microscope until no cancer cells remain. It offers the highest cure rate while sparing as much healthy skin as possible (read more here).
When to choose surgery:
-
Cancer is localized
-
Lesion is large, aggressive, or recurrent
-
Located in cosmetically sensitive areas
3. Non-Surgical Options: Topicals and Cryotherapy
Topical Medications
Creams like imiquimod or 5-fluorouracil are often used for superficial BCCs or precancerous actinic keratoses. They stimulate your immune system or directly destroy cancer cells over several weeks.
Cryotherapy
This treatment freezes the lesion using liquid nitrogen. It’s fast and typically used for pre-cancers or very thin non-melanoma skin cancers.
Best for:
-
Low-risk lesions
-
Patients who prefer non-invasive options
-
Individuals not suited for surgery
4. Radiation Therapy
Radiation uses targeted energy to destroy cancer cells. It’s typically used when surgery isn’t a good option—either due to the patient’s health, the location of the tumor, or recurrence.
Radiation might be considered when:
-
Surgery would be disfiguring or risky
-
The patient is elderly or frail
-
There’s a recurrence after other treatments
It may take several sessions over weeks and is generally well tolerated.

5. Immunotherapy: Activating Your Immune System
For advanced skin cancers, especially melanoma, immunotherapy is changing the game. These treatments help your immune system recognize and fight cancer cells.
Immune Checkpoint Inhibitors
Medications like pembrolizumab or nivolumab are given by IV and are used for melanomas that have spread or cannot be removed surgically.
For Non-Melanoma Cancers
Emerging options include systemic therapies for aggressive or advanced BCC and SCC.
These treatments are usually reserved for serious or metastatic cases, but they’ve led to remarkable outcomes for some patients.
Quick Comparison: Pros and Cons
Here’s a simple breakdown:
| Treatment | Pros | Cons |
|---|---|---|
| Excision | High cure rate, fast, outpatient | Leaves a scar, may need stitches |
| Mohs Surgery | Most precise, spares healthy tissue | Longer appointment, not always available |
| Topicals | Non-invasive, at-home treatment | Takes weeks, may irritate skin |
| Cryotherapy | Fast, cost-effective | Risk of blistering, may miss deep cancer |
| Radiation | No incision, good for hard-to-reach areas | Multiple visits, possible skin changes |
| Immunotherapy | Good for advanced/metastatic cases | Expensive, systemic side effects possible |
Every Patient is Unique
There’s no one-size-fits-all answer. Two patients with the same type of skin cancer might receive completely different treatments depending on their overall health, goals, and the details of their diagnosis.
That’s why it’s so important to speak with a board-certified dermatologist. They’ll help you weigh the pros and cons, answer your questions, and design a treatment plan that fits your needs and lifestyle.
