A biopsy usually involves taking cells or samples from the mole to be analyzed in a lab, according to the Mayo Clinic. Moles are usually just clusters of pigment cells called melanocytes, according to the Cleveland Clinic, but sometimes they can become cancerous. A biopsy helps determine if there is anything wrong with the mole, like melanoma, the deadliest form of skin cancer.
Skin tags are thought to occur from skin rubbing up against skin, since they are so often found in skin creases and folds. Studies have shown existence of low-risk HPV 6 and 11 in skin tags, hinting at a possible role in its pathogenesis. Acrochorda have been reported to have a prevalence of 46% in the general population. A causal genetic component is thought to exist. They also are more common in women than in men. Acrochorda were once thought to be associated with colorectal polyps, but studies have shown no such connection exists. Rarely, they can be associated with the Birt–Hogg–Dubé syndrome, acromegaly, and polycystic ovary syndrome.
Lemon juice is a powerful antiseptic, and it also contains citric acid which helps to dry out skin tags by decomposing the cells. Take a half of fresh lemon and apply the juice to a cotton ball. Apply this directly to the skin tag and leave it on without washing it off. You can apply this up to three times a day and continue the routine until the skin tag falls off.
Michelle Nguyen, a dermatologist and the director of Mohs micrographic surgery at Tufts Medical Center in Boston, tells Allure that what we call skin tags are really just benign skin lesions composed of normal skin tissue. New York City dermatologist Joshua Zeichner adds that skin tags, comprised of extra skin and fat, can happen to anyone. There is, however, a genetic component to them, and people whose parents had them are more likely to get them themselves.

A mole, known by the medical term nevus, is a brown or black growth that occurs on the skin when cells grow in a cluster, rather than spread out. Moles, which can appear anywhere on the skin’s surface, may be present at birth or develop later in life. Over time, some moles change, others disappear and still others remain the same. People with fair complexions, red or blond hair, and blue or green eyes are more apt to have moles.
And speaking of cancer, it’s generally not something you need to worry about with regular old skin tags. Dr. Farber says that, “If anything changes quickly, is unusually painful, or concerns you, it’s worth getting it examined to confirm it’s a benign skin tag …. Skin tags tend to grow very slowly. Any growth that changes quickly is a reason to get examined by a dermatologist.”
Acrochordons are harmless and do not require removal. Typical skin tags can be removed for comfort or cosmetic purposes either by scissor excision, electrocautery (burning), or cryosurgery (freezing). Skin tags with long, narrow stalks can become twisted, cutting off the blood supply and abruptly turning the tag dark brown or black. If a skin tag appears that it is changing or becomes painful, it should be examined by a dermatologist to exclude other, potentially harmful diagnoses.
"Skin tags are these fleshy little bumps that are just annoying as can be. Skin tags can rub against clothing or get caught on jewelry and then they can get really irritated and inflamed. Some people’s skin tags even bleed. Skin tags often form in areas of friction. They'll appear around the neck, under the arms, on our thighs, even around the eyelids," says Geraghty. If you want to get rid of skin tags, read on for advice from Geraghty about how to remove skin tags at the dermatologist's office.
According to Live Science, a skin tag is basically just a skin growth that can be smooth or irregular. It may attach to the skin by a stalk. But Katy Burris, MD, an assistant professor of dermatology at Columbia University and board-certified dermatologist practicing at Columbia University Medical Center in New York City, puts it simply: “A skin tag is a soft growth of normal skin that appears like a small tag. They tend to appear in areas of high friction, where skin may rub clothing or other skin.”
