A wart looks like a lesion and behaves like an infection. Everything that frustrates people about warts — the recurrence, the spread, why the same treatment works differently on a hand and a foot — follows from that one fact.
WhatsApp the clinic →Every destructive treatment — cryotherapy, electrocautery, laser, acids — removes the lesion. None removes virus from surrounding skin that still looks normal. A retrospective review of 560 hand and foot wart patients found 19.6% overall recurrence and attributed it to insufficient antiviral immune effect against latent HPV even when the visible tissue had been destroyed.
In that dataset, recurrence ran at 12% for feet only, 27.3% for hands only, and 31.3% in people with both. Thickness of overlying skin, how heavily the area is used, and how much infected tissue a treatment can actually reach all vary by location. A plan that works for a plantar wart is not automatically the plan for a periungual one.
Spontaneous resolution rates of 65% to 78% are reported, and roughly 40% of warts in children clear within two years untreated. That is not an argument for doing nothing — warts spread, they hurt on weight-bearing skin, and they become more resistant the longer they persist. It is an argument for honesty about what treatment buys: speed and containment, in a condition that frequently resolves on its own timeline.
Treating once and stopping when the visible wart has gone. Picking or shaving over lesions, which spreads virus. And assuming any rough raised lesion is a wart — treating a corn or a seborrhoeic keratosis with liquid nitrogen achieves nothing but discomfort.
“A wart is a viral infection wearing the costume of a blemish. Destroying the lesion does not remove the virus — which is why the recurrence figure, not the clearance figure, tells you what to expect.”
We set the interval deliberately rather than by diary convenience, because the evidence says interval changes outcome. Where lesions are numerous, long-standing or have already failed a course, the plan usually needs to change rather than repeat — that is a different conversation from booking another freeze.
Because destroying the lesion does not eliminate virus in surrounding skin. Latent HPV in tissue that looked normal can produce a new wart at or near the same site. Reported recurrence after cryotherapy ranges from 16.7% to 35%.
Often. Spontaneous resolution rates of 65% to 78% are reported, and about 40% of warts in children clear within two years untreated. Treatment is chosen for speed, spread, discomfort or site.
A 560-patient review found 12% recurrence for foot-only warts, 27.3% for hand-only and 31.3% for both. Site, skin thickness and how much infected tissue treatment reaches all differ.
It is the most common, not automatically the best. A network meta-analysis of palmoplantar warts found cryotherapy had the highest odds of recurrence and the highest adverse event profile of the modalities compared.
Yes. Warts spread by contact, and picking or shaving over them disperses virus. Covering them where practical matters as much as the treatment.
No. This covers cutaneous warts on hands, feet, face and body. Anogenital warts are a separate clinical situation requiring different care.
