Other skin conditions such as warts and moles can resemble skin tags. Since some moles may be cancerous, it’s best to have your skin tags examined by a doctor. Your dermatologist or family doctor will be able to diagnose skin tags. They’ll likely do this through a visual exam. If they have any doubt about the diagnosis, they may also perform a biopsy.
Not sure if your skin lesion is actually a wart? Dr Yip explains how to tell the two apart: “A skin tag is usually soft and hangs off the skin with a narrow base. Warts are rough, scaly and raised bumps on the skin surface caused by viruses, therefore they can spread easily to other body areas and may be contagious to others.” If you can’t figure out which one has taken up residence on your body, it’s best to see your GP or dermatologist. Moles can also look similar to skin tags, so when in doubt (as some moles can be cancerous), it’s always best to get them checked by a skin professional. 
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.

Some essential oils are quite useful in treating skin issues, including skin tags. Well known for its antiseptic and antibacterial properties, tea tree oil is particularly beneficial for skin issues including skin tags. Tea tree oil comes from the Southeast Australian coast. The oil has many health and beauty benefits including skin benefits, treating fungal infections, and clearing coughs and congestion. (4)
A topical application of liquid iodine may help remove skin tags. It works by breaking down skin cells, so it is extremely important that you only apply to the skin tag and avoid the healthy surrounding skin. To be safe, carefully apply coconut oil to a one-half inch area around the skin tag to create a barrier. Then apply a couple of drops of iodine with a sterile cotton swab. Repeat twice each day until the skin tag falls off.
The best method for mole removal depends on different characteristics of the mole including size, shape, and color. With most moles (pigmented areas) we are either born with them, or they appear over time as we exose our skin to the sun. For flat moles, skin tags, or protruding moles that have been relatively stable since birth (with no rapid growing, shape changing, etc.) treatment with laser or excision can remove them easily. Other moles that have changed in color or contour should be removed for biopsy to determine if they are associated with skin cancer.
Factors associated with pregnancy are setup for skin tags. The body is in a general state of growth during pregnancy and all kinds of skin lesions grow during this time. That state of growth, coupled with a heavier-than-normal body weight and possible gestational diabetes (which may be correlated to skin tags), and increased friction in areas of rubbing, like the inner thighs or underarms, can all lead to skin tags during pregnancy.
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.”
Your dermatologist may become concerned if one of your moles has changed shape or color, as this may be an indicator of skin cancer. Most moles are less than a ¼-inch in size, so any mole that is larger should be checked by your doctor. Identifying and treating skin cancers early helps avoid spreading of the cancerous cells to other parts of the body. Uncommon moles, also called dysplastic nevi, may:

Skin tags are usually harmless, so treatment isn’t necessary unless the lesion causes irritation. Although home remedies and over-the-counter products are effective, inexpensive solutions, see a doctor if a skin tag doesn't respond to home treatment, bleeds, or continues to grow. Several procedures can successfully remove a skin tag with minimal pain and scarring.
Rub on aloe vera. You can either snip off a piece of an aloe vera plant or squeeze it to get the gel or you can purchase a bottle of aloe vera gel at a store. Get a cotton swab and dip it in the gel. Wipe it on your tag as often as you like. This method relies on the natural curative properties of aloe vera and its effectiveness is hit or miss.[12]
Tie it off. You can use fishing line, dental floss, or a thin cotton string in this method. Tie the string around the base of your skin tag. Tighten the tie until it is firm, but not painful. Snip off the excess and leave the string in place. Your skin tag should fall off due to lack of circulation. This is a version of what doctors can perform in their office using sterile tools.[24]
Skin tags are thought to occur from skin rubbing up against skin, since they are so often found in skin creases and folds.[2] Studies have shown existence of low-risk HPV 6 and 11 in skin tags, hinting at a possible role in its pathogenesis.[4] Acrochorda have been reported to have a prevalence of 46% in the general population.[5] A causal genetic component is thought to exist.[6] 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.[7] Rarely, they can be associated with the Birt–Hogg–Dubé syndrome, acromegaly, and polycystic ovary syndrome.[8]
Certain endocrine syndromes, metabolic syndrome, and hormonal imbalances. Researchers have found that certain hormone-related syndromes, including  polycystic ovarian syndrome and metabolic syndrome, may be related to skin tags. In fact, a small study of 110 patients with skin tags found 70 had diabetes. Additionally, researchers noted that patients with skin tags also had higher blood pressure. (4)
