4 min read

Medical data indicates that skin lesion removal is one of the most common dermatological procedures performed. To answer the question, is lesion removal a surgery?, the answer depends on the specific technique used, with options ranging from minor outpatient procedures to more involved surgical excisions.

Quick Summary

The process of removing a lesion can be either surgical or non-surgical, depending on factors like size, location, and whether the growth is benign or potentially cancerous. Techniques range from freezing and scraping to surgical excision.

Key Points

It's not always surgery: Many lesion removals are non-surgical, including cryotherapy, laser therapy, and shave excision, used for benign or superficial growths.
Surgical vs. Non-Surgical: The choice of method depends on the lesion's nature, size, depth, location, and potential for malignancy.
Excision is a surgical procedure: Standard surgical excision involves cutting out the lesion and often requires stitches, especially for suspicious growths.
Diagnosis is key: Tissue from surgical excisions is sent to a lab for pathology to confirm the diagnosis and ensure clear margins, which is crucial for treating potential skin cancers.
Minimal Discomfort: Most procedures are performed under local anesthesia, meaning the area will be numb and you should feel little to no pain during the removal itself.
Recovery Varies: Healing time depends on the specific procedure; non-surgical methods typically have shorter recovery, while surgical excisions require more careful wound care for a few weeks.
Scarring is Possible: Any procedure that breaks the skin can result in a scar, but healthcare providers use techniques to minimize their appearance.

What are skin lesions?

Skin lesions are abnormal growths or irregularities that can appear anywhere on the body. They vary widely in size, shape, and color. Lesions can be benign (non-cancerous), pre-cancerous, or malignant (cancerous). Common types include moles, warts, skin tags, cysts, and different forms of skin cancer like basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The decision to remove a lesion is based on medical necessity (e.g., suspected malignancy, causing discomfort) or for cosmetic reasons.

The spectrum of lesion removal techniques

The medical community views lesion removal on a spectrum, with some methods considered surgical and others non-surgical. The procedure chosen is determined by a dermatologist or surgeon after a thorough evaluation of the lesion's characteristics.

Surgical Lesion Removal: When and Why

Surgical lesion removal involves procedures that require an incision and may necessitate stitches. These methods are typically used for suspicious, deeply embedded, or larger lesions to ensure complete removal and allow for pathological examination.

Surgical Excision

This is a common minor surgical procedure that involves cutting out the entire lesion using a scalpel. A small margin of healthy tissue around the lesion is often removed as a safety measure, especially if cancer is suspected, to ensure clear margins.

Performed under local anesthesia.
The wound is closed with stitches, which may dissolve or need removal in 1–3 weeks.
Provides tissue for a biopsy to confirm the diagnosis.

Mohs Micrographic Surgery

Mohs surgery is a highly specialized surgical procedure used to treat certain skin cancers, particularly in cosmetically sensitive areas like the face.

Removes skin layer by layer, with each layer examined under a microscope immediately.
Continues until no cancer cells are found.
Preserves the maximum amount of healthy tissue.

Non-Surgical Options for Lesion Removal

For many benign or superficial lesions, non-surgical methods are effective and less invasive. These procedures often have shorter recovery times and may result in minimal scarring.

Cryotherapy

Cryotherapy involves freezing the lesion using liquid nitrogen. The extreme cold destroys the targeted tissue, causing it to blister and eventually fall off.

Effective for warts, actinic keratoses, and skin tags.
Quick procedure, usually less than a minute.
No stitches required.

Shave Excision

This technique uses a small, sterile blade to shave off the raised portion of a lesion, like a mole, flush with the skin.

Local anesthetic is used.
No stitches are typically needed.
Bleeding is controlled with medication or cautery.

Laser Therapy

Laser treatments use focused light energy to remove or destroy lesions. Different types of lasers are used for various types of lesions.

Suitable for pigmented or vascular lesions.
Reduces damage to surrounding healthy tissue.
Often quick with minimal downtime.

Curettage and Electrodessication

This procedure involves scraping the lesion with a curette and then using a high-frequency electrical current to burn the base and destroy any remaining cells.

Used for certain superficial lesions.
Combines scraping with heat to increase effectiveness.

Surgical vs. Non-Surgical Lesion Removal Comparison


Feature	Surgical Excision	Cryotherapy (Non-Surgical)	Laser Therapy (Non-Surgical)	Mohs Surgery (Surgical)
Invasiveness	Moderately Invasive	Minimally Invasive	Minimally Invasive	Moderately Invasive, Specialized
Best For	Suspicious, large, or deeply embedded lesions; tissue biopsy required	Benign lesions like warts, skin tags, actinic keratoses	Pigmented lesions, sunspots, hair removal	Complex or high-risk skin cancers
Biopsy Possible	Yes	No (tissue is destroyed)	Sometimes, depends on laser type and purpose	Yes (immediate, same-day pathology)
Scarring	Inevitable, though surgeons minimize it	Low risk, temporary redness or blistering common	Can be minimal; reduces sunspots and scars	Highest cure rate, with careful reconstruction to minimize scarring
Recovery	1–3 weeks for wound healing, stitches may be involved	Blistering and scabbing for 1–3 weeks	Quick, usually no downtime	Varies based on extent of removal; reconstruction impacts healing time

What to Expect During and After Lesion Removal

Before the procedure

Your doctor will discuss the reasons for removal, explain the procedure, and outline potential risks and benefits. Be prepared to discuss your medical history and medications. You may be advised to wear loose-fitting clothing and arrange for transportation if sedation is involved.

During the procedure

Most procedures are performed in a doctor’s office under local anesthesia, so you will be awake but the area will be numb. You may feel pressure but not pain. The duration varies from a few minutes to an hour, depending on the technique.

Aftercare and recovery

Following your doctor's aftercare instructions is crucial for proper healing and to minimize scarring.

Keep the wound clean and dry for the first 24–48 hours.
Apply petroleum jelly and a nonstick bandage as directed.
Avoid strenuous activity that could stretch the wound.
Monitor for signs of infection, such as increased redness, swelling, or pus.
Protect the area from sun exposure.

In many cases, any resulting scar will fade over time.

Conclusion: Making an informed decision

Ultimately, the question, is lesion removal a surgery?, has a nuanced answer: sometimes yes, sometimes no. The best approach depends on the individual lesion and your health goals. A suspicious lesion often requires surgical excision to allow for a definitive diagnosis via pathology, while benign or superficial growths may be removed with less invasive non-surgical methods. An open discussion with your dermatologist about the risks, benefits, and expected outcomes of each option is the best way to determine the right path forward for your health. Whether surgical or non-surgical, these procedures offer effective ways to address skin irregularities, ensuring both health and peace of mind.

Frequently Asked Questions

Most lesion removal procedures are performed with local anesthesia to numb the area, so you will not feel pain during the process. After the procedure, some mild soreness or discomfort is normal but can typically be managed with over-the-counter pain medication.

Any procedure that cuts the skin has the potential to leave a scar. Surgical excisions usually result in a scar, but dermatologists use careful techniques to minimize its appearance. Non-surgical options like cryotherapy or laser therapy may cause temporary redness or minimal scarring.

Recovery time varies by procedure. Non-surgical methods like cryotherapy often involve minimal downtime, with healing in 1–3 weeks. Surgical excisions may require 1–3 weeks for wound healing and stitch removal, and a longer period for the scar to fade.

A doctor evaluates the lesion's size, shape, location, depth, and overall appearance. The primary concern is ruling out or treating malignancy. For suspicious lesions, a surgical biopsy or excision is often necessary. For benign lesions, the decision may be based on cosmetic or comfort factors.

If there is any suspicion of malignancy, the removed tissue is typically sent to a pathology lab for a histopathological analysis. A pathologist examines the cells under a microscope to provide a definitive diagnosis and check for clear margins.

Yes, depending on the type and stage of skin cancer. Options can include Mohs micrographic surgery, cryotherapy for superficial cancers, and certain topical medications or photodynamic therapy.

You may be asked to avoid certain medications that increase bleeding risk. Your doctor will provide specific instructions, which may include showering beforehand with antibacterial soap and not wearing makeup or lotions in the area of the procedure.
