Dr Yip notes that while it’s uncommon to experience an infected skin tag, it’s likely they may become red, inflamed and itchy if they're constantly rubbing against clothing and jewellery. “If there is infection, it is usually red, swollen and painful and may have pus discharge and a malodour [an unpleasant odour].” If this occurs, apply an antiseptic cream to mild irritations or see a dermatologist if the pain is more severe.
Mole removal can be done in either of two ways. Shaving or cutting, shaving is simply shaving the mole to the ski surface and cutting is it's removal with a scalpel, with stitching to close the bed and stop bleeding. Prices vary on size and type whether it looks benign or not, there may be a charge for pathological evaluation. Shaving cost are from 75 to 200 dollars cutting cost a little more because sutures cost more particularly the very fine sutures that are as thin as a strand of hair. (200 to 500). The procedure is painless since it is done with local anesthesia.
I had a fairly large mole on the side of my head next to and above the ear, along where glasses frame would set. I had my Dr. look at it and he said it wasn't the type of mole to worry about and if it caused an issue and I wanted it off he would cut or burn it off. In the last few months it began to grow and had reached the size of a penny and about 1/4" thick, so I thought it was time to have it removed. I was very skeptical about D-Mole however I don't trust Dr. much either so I thought I'd give it a try. Well in about 10 days or so it begin to come off in small pieces like a scab, within days it was completely gone without leaving any kind of sore, or with absolutely no pain. So in a nut shell, this stuff really works. If there is any drawback to it, the odor from the oil is strong, but my wife said it was not offensive to her. What the hay if you need a mole removed and it's not one that may be cancer, give this stuff a try, it works. * - Charlie
Michelle Nguyen, a dermatologist and the director of Mohs micrographic surgery at Tufts Medical Center in Boston, tells Allure that what we call skin tags are really just benign skin lesions composed of normal skin tissue. New York City dermatologist Joshua Zeichner adds that skin tags, comprised of extra skin and fat, can happen to anyone. There is, however, a genetic component to them, and people whose parents had them are more likely to get them themselves.
Shaving: A combination treatment that uses electrocautery and shaving to reduce the appearance of protruding moles. Mole shaving does not remove the root of the mole, so there is no excision scar, however there is a chance it will grow back over time. This procedure is most commonly used on protruding moles in areas that do not heal well with excision (nose).  
Skin tags have been linked to diabetes. "We know that diabetics are more prone to them. More research is needed to know exactly why that is scientifically, but there’s some correlation that we observed with diabetes," says Geraghty. Though doctors don't fully understand why, the body's resistance to insulin might have something to do with it. So, if you have diabetes, you may be at an increased risk of developing skin tags.
Depending on where your skin tags are located, you might not choose any skin tag treatment — out of sight can lead to out of mind. However, you might want to seek skin tag treatment for cosmetic reasons if, for instance, they are on your eyelids and detract from your appearance. Another reason to have a skin tag removed is if it is on an area that gets a lot of friction, even just from wearing clothes, causing irritation and bleeding.
I have them. You might have them, too. In fact, according to a study published in the journal Dermotologica — the only one that provides hard numbers on the subject — 46 percent of 750 randomly selected people studied had them. But I was in my early twenties, and I had no idea what was going on. All I knew was that over the course of several months, a few tiny bumps had appeared — on my genitals, mostly in the fold between my thigh and pubic area. From what I could tell, they were skin-colored. They were not moles. Clearly, I had a sexually transmitted disease (STD). I thought they were warts. I Googled, and then I dearly wished I hadn’t.
