Skin Tags: Causes & When to Get One Checked
What skin tags are, what causes them, the genuine link with diabetes and metabolic health, and what private removal costs in Bedford.
Skin tags are soft, skin-coloured growths that hang slightly off the skin, usually on the neck, underarms, eyelids or groin. They are extremely common and harmless. NHS guidance is clear that you should not try to remove one yourself: infection, bleeding and scarring are real risks even with something this small.
What are skin tags?
Skin tags (the medical term is acrochordons) are soft, skin-coloured or slightly darker growths, usually on a narrow stalk, typically 1–5mm though occasionally larger. The NHS describes them as “soft, skin-coloured growths on the skin” that are “usually small and harmless.” They most often appear on the neck, under the arms, on the eyelids, under the breasts, in the groin, or around the bottom: anywhere skin regularly rubs against skin.
They are very common. A clinical reference source (StatPearls) puts prevalence at “50% to 60% in the general population,” with roughly two-thirds of people developing at least one by their fifties or sixties, and numbers increasing with age.
What a skin tag is made of
A typical skin tag is soft and hangs from a narrow stalk. Beneath the surface is a small core of loose collagen and blood vessels covered by normal skin.

What causes skin tags?
The exact mechanism isn’t fully understood, but the NHS states they are “sometimes caused by skin rubbing against skin,” which is why they cluster in skin folds and areas of friction. Contributing factors identified in the clinical literature include obesity, type 2 diabetes, insulin resistance, and pregnancy: the NHS notes that in pregnancy, “hormonal changes are thought to cause them,” and that with type 2 diabetes, “severe insulin resistance is thought to cause more skin tags to grow.”
There is also a genuine, evidence-backed link between multiple skin tags and metabolic health. A case-control study of 110 patients with two or more skin tags found diabetes present in 52% of that group compared with 10% of matched controls, alongside significantly higher blood pressure, cholesterol and insulin resistance: concluding that skin tags “may represent a cutaneous sign for metabolic syndrome.” A separate study of bariatric-clinic patients found the same pattern: those with skin tags had significantly higher blood pressure, higher HbA1c (a marker of blood sugar control), and a higher rate of diabetes than those without.
Neither study proves a skin tag causes or predicts disease in any one person, but if you have several appearing at once, it’s a reasonable thing to mention to your GP alongside routine health checks, not because the tags themselves are dangerous.
Are skin tags dangerous? When to get one checked
Skin tags are benign. Unlike moles, malignant change is not a realistic concern: the clinical literature describes “very low or no risk of malignancy.” This is a different, lower-stakes safety question than for a pigmented mole: you are not screening for cancer here, you are watching for symptomatic change.
See a GP if a skin tag
The NHS advises seeing a GP if you have a skin tag that:
- gets bigger
- becomes painful
- starts bleeding
- develops into lots of skin tags
Do not try to remove a skin tag yourself. The NHS is explicit on this: “Do not try to remove a skin tag yourself unless a GP recommends it. Risks include infection, bleeding and scarring.” Tying one off with thread or cutting it at home is a genuinely bad idea; it’s a soft tissue growth with a blood supply, not a piece of loose skin.
If you notice several new skin tags appearing at once, particularly alongside other changes (weight gain, increased thirst, tiredness), it’s worth mentioning to your GP given the metabolic-syndrome association above, but this is a general-health conversation, not an emergency.
Can I get skin tags removed on the NHS?
No, not for cosmetic reasons. The NHS position is direct: “You cannot get your skin tag removed on the NHS because it is considered cosmetic surgery. You will usually need to pay to have your skin tags removed.”
That holds even though skin tags can be genuinely irritating: caught by jewellery, rubbed by collars or bra straps. Unless a skin tag is bleeding, growing rapidly, or the diagnosis is in doubt, NHS treatment isn’t available and private removal is the route almost everyone takes.
