What is skin tags and moles?
Skin tags are soft, flesh-coloured growths on a small stalk, typically appearing where skin rubs — the neck, armpits, groin and eyelids — and becoming more common with age, in pregnancy and with higher body weight. Moles are clusters of pigment cells; most adults have between ten and forty, developing through childhood and early adulthood. Both are almost always harmless. The crucial exception is a mole that changes: alteration in size, shape or colour, or a mole that itches, crusts or bleeds, needs urgent assessment to rule out melanoma.
Diagnosis is by examination, with dermatologists using a dermatoscope — a polarised magnifier — to inspect moles in detail. Suspicious lesions are removed and sent for histology; cosmetic removals of clearly benign lesions need no testing beyond routine practice.
Common symptoms
- Skin tags: soft, small growths on a stalk in friction areas
- Tags catching on jewellery, clothing or razors
- Moles: flat or raised brown, black or skin-coloured spots
- New moles appearing in adulthood
- Changes in a mole's size, shape or colour (needs urgent review)
- A mole that itches, crusts or bleeds (needs urgent review)
How long will you wait?
The NHS does not remove skin tags or benign moles, as this is classed as cosmetic — though suspected melanoma is fast-tracked, with an urgent skin cancer referral seen within two weeks — so benign removals are almost entirely a private matter.
Privately, you can typically get a specialist mole check within 3–7 days, with removal of tags or benign moles often done on the day or within 1–2 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- Mole check / dermoscopy. Specialist examination, sometimes with photographic mole mapping, distinguishes harmless moles from suspicious ones.
- Excision with histology. Suspicious or changing moles are removed under local anaesthetic and analysed in the laboratory.
- Shave removal. Raised benign moles can be shaved level with the skin for cosmetic reasons, leaving a subtle mark.
- Snip removal, cryotherapy or cautery. Quick clinic techniques remove skin tags with minimal discomfort.
What does private treatment cost?
As a guide, private skin tag removal typically costs £150–£350 for one or several tags, mole removal £250–£600 per mole including histology where appropriate, and a full-body mole check £150–£300.
Does health insurance cover skin tags and moles?
Private medical insurance draws a firm line here. Assessment of a suspicious or changing mole is covered as genuine medical care on most policies, as is removal and histology where cancer is a realistic concern — and treatment is covered if a melanoma is found. Removing skin tags or benign moles purely for appearance or convenience is cosmetic and excluded by essentially every policy, so those removals are self-funded.
Frequently asked questions
How do I know if a mole needs checking?
Use the ABCDE guide: Asymmetry, Border irregularity, Colour variation within one mole, Diameter over 6mm, and Evolving — any change in size, shape, colour or sensation. The 'ugly duckling' test also helps: a mole that looks different from all your others deserves attention. Any mole that changes, itches, crusts or bleeds should be seen urgently by a GP, who can fast-track assessment if needed. When in doubt, get it checked.
Why won't the NHS remove my skin tags?
Skin tags are completely harmless, so their removal is classed as cosmetic — and with a national waiting list of 7.28 million cases, NHS resources are directed at medical need. It is worth knowing they are inexpensive to remove privately, often in a single short appointment. Avoid home removal kits and tying them off yourself, particularly for larger tags or those near the eyes, where clinic treatment is far safer.
Does removing a mole cause cancer or make it spread?
No — this is a persistent myth worth putting to rest. Properly removing a mole does not trigger cancer or cause spread; in fact, excising a suspicious mole with histology is exactly how melanoma is diagnosed and, when caught early, cured. What matters is complete removal and laboratory analysis of anything doubtful, which is why reputable clinics send removed moles for histology rather than destroying them with lasers unexamined.
