While various treatment methods aim to eliminate warts, there's no guarantee of permanent removal, and the necessary number of sessions can vary widely. This is due to several factors:
-
Resilience of the HPV Virus: The human papillomavirus (HPV) that causes warts can remain dormant within skin cells even after the visible wart is gone. This increases the possibility of recurrence. [Reference: Sterling JC, Gibbs S, Haque Hussain SS, Mohd Mustapa MF, Handfield-Jones SE. British Association of Dermatologists' guidelines for the management of cutaneous warts 2014. Br J Dermatol. 2014 Jul;171(1):696-712. doi: 10.1111/bjd.13104.]
-
Individual Immune Response: Your body's immune system plays a pivotal role in fighting off HPV. A weaker immune response might slow down wart treatment and increase the risk of recurrence. [Reference: Thomas KS, Koller R, Dean T. A multicentre randomized controlled trial of cryotherapy versus salicylic acid as first-line treatment for children with common warts. Br J Dermatol. 2019 Apr;180(4):866-873. doi: 10.1111/bjd.17456.]
-
Type and Location of the Wart: Different wart types and their locations on the body influence their response to treatment. For example, plantar warts on the soles of the feet tend to be more stubborn. [Reference: Lipke MM. An armamentarium of wart treatments. Clin Med Res. 2006 Dec;4(4):273-93.]
Research on Treatment Sessions
-
Wide Range: Studies show that the number of treatment sessions for wart removal can range anywhere from a single treatment to several sessions over weeks or even months. [Reference: Sterling JC, Gibbs S, Haque Hussain SS, Mohd Mustapa MF, Handfield-Jones SE. British Association of Dermatologists' guidelines for the management of cutaneous warts 2014.]
-
No Single Treatment is Superior: No one-size-fits-all treatment exists, and different methods have varying success rates. Your dermatologist will choose the best approach based on your specific case. [Reference: Kwok CS, Gibbs S, Bennett C, Holland R, Abbott R. Topical treatments for cutaneous warts. Cochrane Database Syst Rev. 2012 Sep 12;9(9):CD001781.]
Key Takeaways:
- Don't focus on a specific number: Permanent wart removal isn't always guaranteed, and the number of treatment sessions needed can vary widely.
- Work with your dermatologist: They will develop a personalized treatment plan and guide you through the process, aiming for the best possible long-term outcome.
- Patience is key: Successful wart removal may require multiple treatments and good compliance with your doctor's instructions.
