Aside from genetic predisposition, UV exposure causes most moles to develop. This provides you with the opportunity to minimize your risk of new moles by practicing healthy sun habits. Moles result from all UV exposure, not just from a sunburn or excessive time in the sun. To minimize the chance that sun damage will cause new moles – or skin cancer – to develop on your body use broad-spectrum sunscreen on a daily basis, and avoid indoor tanning. 

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.”
If the skin tag is very small, the first thing Geraghty does is spray the bump with cold liquid nitrogen, a non-toxic substance. It's sprayed out of a can and is approximately -320 degrees Fahrenheit. “We direct this very cold spray of gas onto the spot for a few seconds, then we take a break and then we do a few seconds more and usually that’s enough to make the skin tag fall off within a few days,” said Geraghty.
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.”
Moles are brown or black growths, usually round or oval, that can appear anywhere on the skin. They can be rough or smooth, flat or raised, single or in multiples. They occur when cells that are responsible for skin pigmentation, known as melanocytes, grow in clusters instead of being spread out across the skin. Generally, moles are less than one-quarter inch in size. Most moles appear by the age of 20, although some moles may appear later in life. Most adults have between 10 and 40 moles. Because they last about 50 years, moles may disappear by themselves over time.
Repetitive friction and wearing tight clothes may contribute to skin tags in people who are overweight. According to a medical paper written by dermatologists in Spain, an obese patient, whose job required repeating lifting of her arms, developed a pattern of skin tags along her bra straps from the constant friction. Avoiding tight clothing if you are overweight is suggested.
How should anal skin tags be removed? A skin tag is a noncancerous growth of excess skin. Anal skin tags are typically small and may go unnoticed but can sometimes cause embarrassment or discomfort.
