What are some clear signs you should ask your dermatologist whether or not a mole needs a biopsy? If your mole is asymmetrical, has an irregular border, contains different colors, has a diameter larger than a pencil eraser, or is evolving in some way, you should mention it to your doctor. These are known as the ABCDEs of melanoma, according to the American Academy of Dermatology, because they signify when a mole may be cancerous.

Back in the 1980s, there was some speculation that skin tags were more common in people who went on to develop colon polyps or colon cancer. Subsequent research published in the Archives of Internal Medicine and the Journal of Clinical Gastroenterology, however, found no association. That means people with skin tags had no greater chance of developing colon polyps or cancer. The authors concluded skin tags should not be used as a reason for more intensive screening.

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.
Lemon juice is a powerful antiseptic, and it also contains citric acid which helps to dry out skin tags by decomposing the cells. Take a half of fresh lemon and apply the juice to a cotton ball. Apply this directly to the skin tag and leave it on without washing it off. You can apply this up to three times a day and continue the routine until the skin tag falls off.

While the majority of skin tags are simply destroyed, sometimes tissue is sent for microscopic exam by a health care specialist known as a pathologist, who will determine the exact diagnosis and determine whether an abnormality such as skin cancer is present. Irregular skin growths that are larger, bleed, or have an unusual presentation may require pathology examination to make sure there are no irregular cells or skin cancers.
Use tea tree oil. Tea tree oil may be helpful for certain skin conditions, such as acne, fungal infections, and bug bites, so you can try it on your mole if you like.[11] Brush tea tree oil on the mole twice daily using a q-tip. At night, you can also soak a cotton ball in tea tree oil and secure it over the mole with a Band-Aid. Repeat this method for a month, or however long it takes the mole to go away. However, keep in mind that applying tea tree oil to your skin daily may cause it to burn. Stop if skin irritation occurs.
But that doesn’t mean you should completely ignore skin tags. David Lorschter, MD, founder of Curology and a board-certified dermatologist in San Diego, notes there are exceptions. He says people with a genetic disorder called basal cell nevus system (BCNS) usually exhibit spots of basal cell skin cancer that look like — you guessed it — skin tags. Therefore, people with BCNS should have their skin tags biopsied and screened for cancer on a regular basis.

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.
