With smaller nevi, the growth is cut or ‘shaved’ off flush with the skin with a scalpel or surgical scissors,while larger moles may require cutting out and stitching of wound edges. Very large nevi may call for gradual removal, in which case your physician will remove a little more at each appointment until the entire growth is removed. This is a more serious procedure, calling for a skin graft from another part of the body.
The vast majority of moles are not dangerous. Moles that are more likely to be cancer are those that look different than other existing moles or those that first appear after age 25. If you notice changes in a mole's color, height, size, or shape, you should have a dermatologist (skin doctor) evaluate it. You also should have moles checked if they bleed, ooze, itch, or become tender or painful.
A mole is a skin abnormality that develops when skin grows in a cluster instead of spreading out. These are usually dark, small patches of skin no larger than the size of an eraser head. Although they are most often harmless, some moles can develop into melanoma skin cancer. If you are concerned about a mole that may be cancerous, please refer to our skin cancer treatment page.
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.
Most importantly, don’t take it upon yourself to decide that a growth is benign. At your dermatologist’s office, you’ll have a better shot at getting a solid read on what you have—and whether it’s an issue. And if you want it removed, most doctors will perform removal by freezing with liquid nitrogen (cryosurgery), cautery with an electric current (electrosurgery), or cutting with medical scissors (snip excision).
Hormone elevations, such as those seen during pregnancy, may cause an increase in the formation of skin tags, as skin tags are more frequent in pregnant women. Tags are essentially harmless and do not have to be treated unless they are bothersome. Skin tags that are bothersome may be easily removed during or after pregnancy, typically by a dermatologist.
Make an appointment with a dermatologist. Going about mole removal the safe way is a decision you won't regret. It's extremely important to have your mole examined by a professional rather than trying to remove it yourself, even if you just want it removed for cosmetic reasons. When you see a physician, he or she will be able to tell whether the mole is potentially cancerous. If it is, professional removal is the only safe method, since other methods won't adequately deal with the cancer cells.
While it is true that skin tags often show up in the armpit or neck creases, the skin-on-skin friction is not what’s to blame. Rather, it’s the creases and skin folds that produce a friendly environment for a virus that may cause some skin tags. According to Ben Johnson, MD, founder of holistic beauty brand Osmosis Skincare, “Viruses are much more commonly spread through contact than people realize, but they don’t find the skin an easy place to survive. Creases improve their chances, and on rare occasions, one makes it into the follicle and infects local skin DNA to create skin tags.”
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.
