The causes of skin tags are not entirely clear but their presence in skin fold areas suggests that friction or frequent irritation is a potential cause. The condition appears to have a genetic component (there is a tendency for skin tags to occur in families) but other potential causes include hormonal imbalances. For example, skin tags are associated with agromegaly, the growth hormone disorder.
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).  
Simply thinking about having a mole removed might send a few shivers down your spine, but sometimes it’s just necessary for your health, Gary Goldenberg, M.D., assistant clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai Hospital, tells SELF. If, for example, you have a mole that your doctor suspects or has confirmed through a biopsy is cancerous, excising the mole can help to stop any cancer from potentially growing more. But people also have moles removed for cosmetic reasons or because they’re simply annoying, like if one falls just under your bra strap and always gets irritated, Dr. Goldenberg says.

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.
Most doctors recommend removal of skin tags only when they are irritated or a source of discomfort, or if they constitute a cosmetic problem. Skin tags can be easily removed in the doctor's office by tying or cutting them after injecting a small amount of a local anesthetic. Freezing, a technique sometimes used to remove warts or other benign lesions of the skin, is also sometimes performed for the removal of skin tags.
Most people choose to remove them for cosmetic reasons, especially skin tags that surface on the neck, eyelid, or face. In rare cases, a skin tag can get irritated and infected. In that case, skin tag removal is the best course of action to prevent infection from reoccurring. But, what causes them? And once you have them, you need to know how to get rid of skin tags. We’ll explain it all.
Hemorrhoids (piles) are swollen veins in the rectum and anus. Causes include pregnancy, obesity, diarrhea, low-fiber diet, and prolonged sitting on the toilet. Treatment varies depending upon the severity of the hemorrhoids. Some treatment options include over-the-counter creams and suppositories, stool softeners, warm sitz baths, and hemorrhoidectomies.
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.
