Skin cancer treatment includes a range of medical and surgical procedures designed to remove cancerous cells, prevent the disease from spreading, reduce the risk of recurrence, and preserve healthy skin and surrounding structures.
The most appropriate treatment depends on several factors, including the type of skin cancer, tumor size, location, depth, stage, previous treatments, and the patient’s overall health.
The three main types of skin cancer are:
- Basal cell carcinoma (BCC): The most common type of skin cancer. It generally grows slowly and rarely spreads to distant organs, but it can cause substantial local tissue damage if left untreated.
- Cutaneous squamous cell carcinoma (cSCC): A cancer arising from squamous cells in the skin. Some tumors can invade surrounding tissues and spread to lymph nodes or other organs.
- Melanoma: A potentially aggressive cancer that develops from melanocytes, the pigment-producing cells of the skin. It has a greater tendency to spread than the more common basal and squamous cell carcinomas.
Less common types include Merkel cell carcinoma and certain skin lymphomas, which require specialized treatment.
When detected early, many skin cancers can be treated successfully with surgery or other localized procedures. More advanced cancers may require radiation therapy, immunotherapy, targeted therapy, or combinations of treatments.
Early diagnosis is essential because some skin cancers can spread or cause permanent tissue damage when treatment is delayed.
What Causes Skin Cancer?
Skin cancer develops when genetic changes cause skin cells to grow abnormally and escape the body’s usual growth controls.
One of the most important preventable risk factors is exposure to ultraviolet (UV) radiation from sunlight and indoor tanning devices.
Other factors can also contribute.
Main Risk Factors
- Excessive or cumulative UV exposure.
- A history of sunburns, particularly severe burns.
- Use of tanning beds.
- Previous skin cancer.
- Family history of melanoma or certain other skin cancers.
- Numerous or atypical moles.
- Fair skin that burns easily, although skin cancer can affect every skin tone.
- Weakened immune function.
- Certain inherited genetic conditions.
- Previous radiation exposure.
- Increasing age, especially for some nonmelanoma skin cancers.
Skin cancer can also develop in areas that receive relatively little sunlight, including the palms, soles, and beneath the nails.
Signs and Symptoms of Skin Cancer
The appearance of skin cancer varies according to the type.
Possible warning signs include:
- A new or changing mole.
- A persistent sore that does not heal.
- A growth that repeatedly bleeds or develops a crust.
- A shiny or pearly bump.
- A rough, scaly, or thickened patch.
- A firm or tender skin nodule.
- A dark streak beneath a nail.
- An existing spot that changes in shape, size, or color.
- A skin lesion that looks different from other spots.
The ABCDE Rule for Melanoma
The ABCDE rule helps identify changes that may require dermatological evaluation.
| Letter | Meaning | Warning Sign |
|---|---|---|
| A | Asymmetry | One half looks different from the other |
| B | Border | Irregular, poorly defined, or uneven edges |
| C | Color | Multiple colors or changing pigmentation |
| D | Diameter | Often larger than 6 mm, although melanomas may be smaller |
| E | Evolving | Changes in size, shape, color, elevation, or symptoms |
Some melanomas do not follow all these characteristics.
A new, changing, bleeding, or unusual skin lesion should be examined by a qualified healthcare professional.
How Is Skin Cancer Diagnosed?
Before selecting a treatment, the dermatologist needs to determine whether a lesion is cancerous and identify its type.
1. Clinical Skin Examination
The specialist examines the suspicious lesion and may assess the surrounding skin for additional abnormalities.
2. Dermoscopy
A dermatoscope allows the dermatologist to examine structures and pigmentation patterns that are not readily visible to the naked eye.
3. Skin Biopsy
A skin biopsy involves removing part or all of a suspicious lesion for microscopic examination.
The technique depends on the suspected diagnosis, anatomical site, and lesion characteristics.
A biopsy is essential for confirming skin cancer and establishing the tissue diagnosis.
4. Pathology Examination
A pathologist or dermatopathologist examines the tissue.
The report may describe:
- Cancer type.
- Tumor thickness or depth.
- Aggressive microscopic characteristics.
- Ulceration in melanoma.
- Involvement of surgical margins.
- Other features relevant to treatment decisions.
5. Additional Staging Tests
Depending on the cancer type and risk, the medical team may recommend lymph node examination, imaging, or other studies.
For selected patients with melanoma, a sentinel lymph node biopsy may help determine whether cancer cells have spread to nearby lymph nodes.
Not every patient requires extensive imaging or lymph node surgery.
Main Skin Cancer Treatment Options
There is no single treatment suitable for all skin cancers.
The following approaches are used according to the diagnosis and clinical circumstances.
1. Surgical Excision
Surgical excision is one of the most common and effective treatments for localized skin cancer.
The procedure removes the tumor together with an appropriate margin of surrounding skin.
How Is It Performed?
- The area is examined and prepared.
- Local anesthesia is usually administered.
- The surgeon removes the lesion and a planned margin of tissue.
- The sample is sent for pathological examination.
- The wound is closed using stitches or another reconstructive technique when needed.
When Is Surgical Excision Recommended?
It is commonly used for:
- Many basal cell carcinomas.
- Cutaneous squamous cell carcinomas.
- Melanoma.
- Selected recurrent or higher-risk skin tumors.
For melanoma, the procedure commonly involves a wide local excision, with margins determined by factors such as tumor thickness and clinical guidelines.
Benefits
- Physically removes the cancerous tissue.
- Allows pathological examination of the removed specimen.
- Can be curative for many early-stage tumors.
- Is frequently performed under local anesthesia.
Possible Risks
- Bleeding.
- Infection.
- Scarring.
- Wound separation.
- Changes in sensation.
- Incomplete removal requiring additional treatment.
Recovery depends on the size and location of the wound.
2. Mohs Micrographic Surgery
Mohs surgery is a specialized surgical technique that removes skin cancer in stages while examining the tissue margins under a microscope.
The goal is to remove the entire tumor while preserving as much healthy surrounding tissue as possible.
How Does Mohs Surgery Work?
- The surgeon removes a thin layer of cancerous tissue.
- The tissue is processed and examined microscopically.
- If cancer cells remain at the examined margins, another targeted layer is removed.
- The process continues until the examined margins are clear.
When Is Mohs Surgery Used?
It is particularly valuable for selected basal and squamous cell carcinomas involving:
- The nose.
- Eyelids.
- Ears.
- Lips.
- Other locations where preserving healthy tissue is important.
It may also be recommended for:
- Recurrent tumors.
- Tumors with poorly defined borders.
- Certain aggressive histological subtypes.
- Selected tumors in immunosuppressed patients.
For specific forms of melanoma in situ, especially lentigo maligna, Mohs or another staged excision technique may be considered by an appropriately trained specialist.
It is not automatically the standard approach for every melanoma.
Benefits
- Detailed microscopic assessment of tumor margins.
- Preservation of surrounding healthy tissue.
- Particularly useful in anatomically sensitive areas.
- High cure rates for appropriately selected tumors.
Limitations
- Requires specialist expertise.
- Can take several hours.
- May require reconstructive surgery.
- Is not necessary for every skin cancer.
3. Curettage and Electrodessication
Curettage and electrodessication (C&E) is a procedure that removes selected superficial skin tumors through scraping and controlled application of electrical energy.
How Is It Performed?
The dermatologist uses a curette to scrape the affected tissue.
An electrosurgical device is then used to destroy residual tissue and control bleeding.
The process may be repeated during the same session.
When Is It Appropriate?
It may be considered for:
- Selected small, low-risk basal cell carcinomas.
- Certain low-risk squamous cell carcinomas.
- Some superficial lesions in appropriate locations.
Advantages
- Usually performed in an outpatient setting.
- Generally relatively quick.
- Often does not require stitches.
Limitations
The procedure does not provide the same comprehensive margin assessment as excisional or Mohs surgery.
It is generally inappropriate for:
- Melanoma.
- High-risk invasive squamous cell carcinoma.
- Aggressive or deeply infiltrating tumors.
Possible complications include scarring, pigmentation changes, infection, and recurrence.
4. Radiation Therapy
Radiation therapy uses high-energy radiation to damage cancer cells and prevent them from continuing to grow.
When Is Radiation Used?
Radiotherapy may be considered when:
- Surgery would be difficult or cause substantial functional or cosmetic consequences.
- A patient cannot undergo surgery.
- Additional treatment is necessary after selected high-risk tumor excisions.
- Cancer has spread to nearby structures.
- Advanced disease requires symptom relief.
Radiation may be used for certain basal and squamous cell carcinomas and in selected circumstances involving melanoma.
How Is It Delivered?
Treatment is planned by a radiation oncology team.
Depending on the tumor and technique, radiation may be delivered in several sessions over a defined treatment period.
Possible Side Effects
- Skin redness.
- Irritation.
- Fatigue.
- Changes in skin pigmentation.
- Delayed wound healing.
- Long-term changes in skin texture.
- Other effects depending on the treated area.
Radiation is not necessarily the best option for younger patients or people with certain genetic conditions that increase sensitivity to radiation-related cancers.
5. Cryotherapy or Cryosurgery
Cryotherapy uses extremely low temperatures, commonly delivered with liquid nitrogen, to destroy selected abnormal skin tissues.
When Is Cryotherapy Used?
It is frequently used for actinic keratoses, which are sun-damaged lesions with the potential to develop into squamous cell carcinoma.
In selected circumstances, cryosurgery may also be used for certain low-risk superficial skin cancers.
Benefits
- Usually quick.
- Often performed in a clinic.
- Usually does not require surgical stitches.
Limitations and Risks
- Blistering.
- Pain.
- Pigmentation changes.
- Scarring.
- Incomplete treatment or recurrence.
- Lack of surgical margin confirmation.
Cryotherapy is not an appropriate routine treatment for melanoma or high-risk invasive skin cancers.
A suspicious pigmented lesion should not simply be frozen without an appropriate diagnostic assessment.
6. Photodynamic Therapy (PDT)
Photodynamic therapy combines a light-sensitive medication with a specific light source to destroy selected abnormal cells.
How Does PDT Work?
- A photosensitizing agent is applied to the treatment area.
- The medication is allowed to accumulate in the targeted tissue.
- A designated light source activates the agent.
- The resulting photochemical reactions damage the treated cells.
When Is PDT Used?
It may be considered for:
- Actinic keratoses.
- Selected superficial basal cell carcinomas.
- Certain cases of squamous cell carcinoma in situ, depending on local recommendations.
Advantages
- Generally avoids extensive surgery.
- May provide favorable cosmetic outcomes in selected superficial lesions.
- Can sometimes treat several affected areas.
Limitations
- May require repeated treatments.
- Can cause pain, redness, crusting, or light sensitivity.
- Is less suitable for deeper or aggressive tumors.
- Does not provide the same microscopic margin assessment as surgery.
Photodynamic therapy is not an established substitute for surgical treatment of invasive melanoma.
7. Topical Chemotherapy and Other Prescription Creams
Certain early or superficial skin lesions may be treated with prescription medication applied directly to the skin.
Topical 5-Fluorouracil (5-FU)
5-fluorouracil is a topical chemotherapy medication that interferes with the growth of susceptible abnormal cells.
It may be prescribed for:
- Actinic keratoses.
- Selected superficial basal cell carcinomas.
- Other specific indications based on local guidelines.
Imiquimod
Imiquimod is an immune-response-modifying cream, not a conventional cytotoxic chemotherapy drug.
It may be used for certain superficial basal cell carcinomas and other approved indications.
Advantages
- Non-surgical application.
- Can treat selected superficial lesions.
- May be useful for some patients when surgery is unsuitable.
Side Effects
- Redness.
- Burning.
- Crusting.
- Swelling.
- Skin erosion.
- Discomfort.
A visible inflammatory reaction can occur during treatment, but the intensity of irritation does not reliably demonstrate that all cancer cells have been eliminated.
Topical medications are not appropriate substitutes for standard surgery in invasive melanoma or most invasive squamous cell carcinomas.
8. Systemic Chemotherapy
Systemic chemotherapy involves medication delivered through the bloodstream to treat cancer cells throughout the body.
It may be considered in selected advanced cancers, particularly when other more effective or appropriate treatments are unavailable or unsuitable.
However, its role has changed substantially because immunotherapy and targeted treatments are now preferred in many advanced melanoma cases and selected advanced nonmelanoma skin cancers.
Possible Side Effects
Depending on the medication, chemotherapy can cause:
- Fatigue.
- Nausea.
- Reduced blood cell counts.
- Increased infection risk.
- Hair loss.
- Other drug-specific complications.
Systemic chemotherapy is not a routine treatment for a small, localized basal cell carcinoma or other low-risk skin lesion.
9. Immunotherapy
Immunotherapy uses medications designed to help the immune system recognize or attack cancer cells.
It has become an important treatment for several types of advanced skin cancer.
Immunotherapy for Melanoma
Treatments may include immune checkpoint inhibitors such as:
- Pembrolizumab.
- Nivolumab.
- Ipilimumab.
- Selected combinations, including nivolumab with relatlimab.
Depending on the stage and clinical situation, immunotherapy may be administered:
- Before surgery, known as neoadjuvant therapy.
- After surgery, known as adjuvant therapy.
- For unresectable or metastatic disease.
Immunotherapy for Squamous Cell Carcinoma
For selected advanced cutaneous squamous cell carcinomas, PD-1 inhibitors such as cemiplimab or pembrolizumab may be considered according to the clinical indication and applicable approvals.
Immunotherapy for Basal Cell Carcinoma
In certain advanced basal cell carcinoma cases, immunotherapy may be considered when other treatments, including specific targeted therapies, are unsuitable or have not worked.
Potential Side Effects
Immunotherapy can cause immune-related inflammation affecting organs such as:
- Skin.
- Intestines.
- Liver.
- Lungs.
- Thyroid.
- Other hormone-producing glands.
Some reactions can be serious and require urgent treatment.
Not all patients respond to immunotherapy, and its suitability depends on the cancer type and individual medical circumstances.
10. Targeted Therapy
Targeted therapy uses medications designed to interfere with specific molecular pathways involved in cancer growth.
The treatment selected depends on the type of skin cancer and, in some cases, specific genetic changes in the tumor.
Targeted Therapy for Melanoma
Some melanomas contain changes in the BRAF gene, particularly BRAF V600 mutations.
For eligible patients, treatment may include combinations of:
- BRAF inhibitors.
- MEK inhibitors.
Examples include combinations involving dabrafenib and trametinib or encorafenib and binimetinib.
These medications are not suitable for every melanoma. Molecular testing helps determine eligibility.
Targeted Therapy for Basal Cell Carcinoma
Certain advanced basal cell carcinomas can be treated with medications that inhibit the Hedgehog signaling pathway.
Examples include:
- Vismodegib.
- Sonidegib.
These medications may be considered when the cancer cannot be adequately treated using surgery or radiation, subject to the specific indication.
Potential Side Effects
Depending on the drug, effects may include:
- Fatigue.
- Skin reactions.
- Muscle cramps.
- Taste disturbances.
- Hair changes or loss.
- Gastrointestinal symptoms.
- Other treatment-specific complications.
Some medications can cause serious harm during pregnancy and require strict pregnancy-prevention precautions.
11. Laser Therapy
Laser treatment uses concentrated light energy to destroy or remove selected skin tissues.
Although lasers are widely used in dermatology, their role in treating confirmed invasive skin cancer is limited.
When Might Laser Treatment Be Considered?
Certain laser techniques may be used in selected cases involving:
- Actinic keratoses.
- Some superficial skin lesions.
- Certain superficial basal cell carcinomas in specialized settings.
Important Limitations
Laser destruction may prevent comprehensive pathological examination of the treated tissue and its margins.
For this reason, it is generally not the preferred treatment for invasive melanoma, aggressive squamous cell carcinoma, or other high-risk tumors.
A changing or suspicious mole should not be removed with a cosmetic laser before an appropriate medical assessment and biopsy when indicated.
Which Treatment Is Best for Each Type of Skin Cancer?
Treatment varies according to tumor type, stage, location, and risk.
| Skin Cancer Type | Common Treatment Approaches |
|---|---|
| Low-risk localized BCC | Surgical excision, selected curettage procedures, or other carefully chosen local therapies |
| High-risk or recurrent BCC | Mohs surgery or other techniques with appropriate margin assessment |
| Locally advanced BCC | Targeted therapy, selected immunotherapy, or other specialized treatment |
| Low-risk localized cSCC | Surgical excision or selected local procedures |
| High-risk cSCC | Excision with appropriate margin assessment, frequently Mohs surgery |
| Advanced or metastatic cSCC | Immunotherapy, radiation, surgery, or combinations |
| Early-stage melanoma | Wide local excision, with additional staging procedures when indicated |
| High-risk resectable melanoma | Surgery and, for selected patients, immunotherapy or targeted therapy |
| Advanced melanoma | Immunotherapy, mutation-directed targeted therapy, and selected local or systemic treatments |
These are general treatment approaches, not universal prescriptions.
How Long Does Skin Cancer Treatment Take?
The overall treatment timeline depends on the cancer and the procedure.
Local Surgery
Many small lesions can be treated during an outpatient visit.
Wound healing may take weeks, depending on the size and location.
Mohs Surgery
The procedure may require several hours because each layer of removed tissue is examined before deciding whether further excision is necessary.
Cryotherapy
A session is usually brief, although treated tissue may take several weeks to heal.
Photodynamic Therapy
Treatment includes medication application, an incubation period, and light exposure. Additional sessions may be required.
Radiation Therapy
Often involves a scheduled course of treatments over days or weeks.
Immunotherapy and Targeted Therapy
May continue for months or longer according to the disease, response, tolerability, and treatment plan.
Recovery After Skin Cancer Treatment
Recovery depends on the depth and extent of the treatment.
After Surgery
The medical team may recommend:
- Keeping the wound clean.
- Following dressing instructions.
- Avoiding strain on the surgical area.
- Monitoring for infection.
- Returning for stitch removal when necessary.
- Attending follow-up appointments.
After Topical or Light-Based Treatment
Temporary redness, crusting, soreness, or peeling may occur.
Patients should follow the prescribed wound-care instructions rather than applying additional products without medical advice.
During Systemic Treatment
Patients may require regular blood tests, medical assessments, and monitoring for adverse effects.
Always report new or worsening symptoms during immunotherapy, targeted therapy, or chemotherapy.
Can Skin Cancer Be Cured?
Many skin cancers are highly treatable, particularly when diagnosed early.
However, the prognosis varies.
Basal Cell Carcinoma
Most localized tumors can be treated successfully, but recurrence or extensive local damage is possible.
Squamous Cell Carcinoma
Many localized cases are curable. Tumors with high-risk features may have a greater possibility of recurrence or metastasis.
Melanoma
Early-stage melanoma often has a favorable prognosis when treated appropriately.
More advanced melanoma may require intensive treatment and can be life-threatening.
Modern immunotherapies and targeted medications have improved outcomes for many patients with advanced disease, but they do not guarantee a cure.
No responsible specialist can promise a 100% cure rate for every skin cancer.
Can Skin Cancer Return After Treatment?
Yes.
Some cancers recur at the original site, while patients who have developed one skin cancer may also be at increased risk of developing additional skin cancers.
Follow-up schedules depend on:
- Cancer type.
- Tumor stage.
- Aggressive pathological features.
- Previous treatment.
- Immune status.
- Personal history of skin cancer.
- Family history.
Patients with melanoma or high-risk squamous cell carcinoma may require additional examination of lymph nodes or other tests, depending on their individual risk.
How to Reduce the Risk of Skin Cancer
Although not all cases can be prevented, reducing UV exposure can lower risk.
Sun Protection
- Use broad-spectrum sunscreen with SPF 30 or higher.
- Reapply according to the product instructions, particularly after swimming or sweating.
- Wear protective clothing.
- Use wide-brimmed hats and UV-protective sunglasses.
- Seek shade when sunlight is intense.
- Avoid indoor tanning beds.
Skin Self-Examination
Become familiar with the usual appearance of your skin.
Check for new or changing spots, particularly on areas that may be difficult to see.
Ask someone to help examine the back or scalp when appropriate.
Dermatological Follow-Up
People with a history of skin cancer or other important risk factors may benefit from periodic professional skin examinations.
There is no single examination schedule suitable for everyone.
Frequently Asked Questions About Skin Cancer Treatment
