Skin tags can happen on any part of the body but are most commonly found on the neck, under arms, under the breasts and in the groin area. Why these areas? “It is thought that they are related to chronic friction, which is why they are more common in overweight or obese persons,” said Sorensen. “Higher levels of growth factors (like during pregnancy), insulin resistance (more common in people with diabetes) and possibly a genetic component also could all play a part as well.”
Skin tags are extremely common small tissue growths on the skin’s surface. Up to half of all people may get one at more at some point in their lifetime. Most often, skin tags are harmless, painless, and don’t grow or change. While you can find them all over your body, skin tags often form on areas of the body subject to rubbing. You are most likely to find them on the neck, armpits, trunk and in body folds. (1)
Moles are extremely common skin growths, most adults have from 10 to 40 moles, and they can develop on virtually any part of the body. They may be flat or raised, and nearly color brown, black, pink, red, white, purple, blue, or flesh colored. Most moles are non-cancerous (benign), and no cause for concern. However, a mole can sometimes develop into melanoma, a dangerous form of skin cancer.
Don't ignore a mole that's changing. If you don't like the prospect of having surgery, you might be tempted to let your mole be and forget about it. That's usually fine, unless you notice that the mole has changed over time. A changing mole can be a sign of the presence of cancer cells, so you should have any mole checked out by your doctor. Use the ABCDE guide to examine your mole. If you notice the following, be sure to make an appointment with a doctor:
“My preferred method is snip excision (cutting off the skin tag base with sterile surgical scissors) and cautery of the base to help stop bleeding and reduces the chance of regrowth,” says Dr Yip. “This method allows multiple skin tags to be removed in the one session and is usually scarless. Extensive treatment may need local anaesthetic. Other methods used by dermatologists include cryotherapy (freezing), surgical excision and ablative laser.”
Shaving: A combination treatment that uses electrocautery and shaving to reduce the appearance of protruding moles. Mole shaving does not remove the root of the mole, so there is no excision scar, however there is a chance it will grow back over time. This procedure is most commonly used on protruding moles in areas that do not heal well with excision (nose).
The vast majority of skin tags are benign tumours but one study of 1,335 lesions found that four were basal cell carcinomas and one was a squamous cell carcinoma. Nevertheless, the authors suggest that the malignancy potential of skin tags is low. Patients experience few, if any, problems with skin tags although pruritus and discomfort can occur if the lesions are snagged by jewellery.
Insulin resistance, which may lead to type 2 diabetes and prediabetes, may also play a role in the development of skin tags. People with insulin resistance don’t absorb glucose effectively from the bloodstream. According to a 2010 study, the presence of multiple skin tags was associated with insulin resistance, a high body mass index, and high triglycerides.
