Standard Treatment and Removal Options

When a skin growth is confirmed to be a benign papilloma—such as a common skin tag or a viral wart—the decision to remove it is often up to you. Unless a growth is painful, catching on clothing, or shows signs that require a biopsy, “watching and wait” is a perfectly safe and standard option ^[1][2].

If you do choose removal, several effective medical techniques are available, each with its own balance of healing time and potential side effects. Remember that treatments for a skin tag, a wart, and a suspected cancer are not interchangeable.

Removing Skin Tags (Acrochordons)

For skin tags that are bothersome or unsightly, dermatologists use several “in-office” methods for quick removal.

• Snip or Scissor Excision: The doctor uses specialized sterile scissors to “snip” the tag at its base. This is often an effective method because it is fast, and the clinician can choose it based on diagnosis and patient priorities ^[3][2]. One study comparing specific methods found snip excision often results in lower pain scores than certain laser types ^[3].
• Electrosurgery (Electrodesiccation): A tiny needle uses an electric current to “burn” the tissue. This method cauterizes the spot immediately, which prevents bleeding ^[2]. While very effective, it can sometimes leave a small, indented (atrophic) scar ^[4].
• Cryotherapy: The growth is frozen using liquid nitrogen. This causes the tissue to die and eventually fall off. While common, it can be less precise than snipping and may require more than one session ^[5][4].
• Laser Therapy: Various lasers can be used to vaporize the tag. While high-tech, laser removal can sometimes cause more redness and temporary skin color changes than traditional snipping ^[3].

Treating Warts (Viral Papillomas)

Warts are caused by a virus (HPV), so treatment focuses on either destroying the infected skin or helping your immune system recognize and fight the virus ^[6].

• Salicylic Acid: This is often the first-line treatment. It works by slowly dissolving the “warty” layers of skin over several weeks ^[7]. Important Safety Limits: Use this only for a clinician-confirmed common wart. Never use it on the face, genitals, mucous membranes, broken skin, or an undiagnosed growth.
• Cryotherapy: In the office, a doctor can apply a much colder freeze than over-the-counter kits. This often causes a small blister to form under the wart, which helps “lift” it away ^[8]. It typically requires multiple sessions spaced a few weeks apart ^[7].
• Immunotherapy: For “recalcitrant” warts (those that won’t go away with freezing or acid), specialists may occasionally inject a tiny amount of an antigen—such as Candida or MMR—directly into the wart ^[9][10]. This is a clinician-administered, often off-label option with variable evidence, not a universally standard next step ^[11][10].

Risks and Side Effects

While removal procedures are minor, they are not without risks, particularly regarding the appearance of the skin after healing.

Skin Color Changes

The risk of pigment changes is a major consideration, especially for people with darker skin tones (Fitzpatrick types IV–VI) ^[12].

• Hypopigmentation: The treated area may heal as a permanent white or light-colored spot. This is a common risk with cryotherapy and electrosurgery ^[4][13].
• Hyperpigmentation: The skin may heal with a dark brown or “stained” appearance. This is common after laser treatments or any procedure that causes significant inflammation ^[12][3].

Scarring and Infection

Any procedure that breaks the skin carries a small risk of infection or scarring ^[14]. Electrosurgery and cryotherapy are more likely to cause minor scarring or blistering compared to a clean snip excision ^[4][8].
Aftercare: Expect some pain, blistering, or crusting. Keep the wound clean. Contact your clinician for spreading redness, pus, fever, worsening pain, or failure to heal.

Special Considerations for Diabetes

If you have diabetes, your skin may heal more slowly, and your risk of infection is higher ^[15].

• Delayed Healing: High blood sugar can interfere with the body’s ability to repair tissue, making even a small snip or freeze take longer to close ^[15].
• Foot Care: Warts or growths on the feet require extra caution. Because of potential nerve damage (neuropathy) or poor circulation, you may not feel a secondary infection or a non-healing ulcer starting at the site of a removed wart ^[16][17].

Always seek clinician advice before treating a foot or other lesion if you have diabetes, neuropathy, poor circulation, or immune suppression ^[15].
