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:
Moles can be removed a number of ways, most commonly by numbing the area and then shaving them off or cutting them out and closing the area with stiches. The method of removal is determined by a number of factors including appearance, size, location, and type of mole. For example, if a mole is just bothersome because it is raised, shaving it flat is usually the best approach. Similarly, if a mole is abnormal appearing and small, it also is typically shaved. Conversely, moles that are growing irritated hairs are usually best treated with complete removal and closure with stiches. Moles can grow back after shaving (and occasionally even after removing and closing area with stiches).
Some other studies have suggested that skin tags may be associated with thyroid problems. An article published in December 2016 in the Journal of Evolutionary Medicine found that about 11 percent of people with thyroid issues had achrocordons, or skin tags. These patients tended to have a higher number of thyroid nodules and thyroid volume. This, they hypothesize, is because “skin tags and thyroid changes may be associated with high levels of circulating insulin.”
Avoid using mole removal creams. These creams are often sold online, marketed as a cheap, noninvasive alternative to surgical removal. In fact, mole removal creams can end up leaving deep pockets in your skin, since they go beyond the mole and dig into the skin underneath, causing irreparable damage. The small scar left behind by surgical removal is minimal in comparison.
