New York Dermatologist Dr. Lawrence Jaeger is the medical director of Advanced Dermatology Associates, a network of treatment clinics which specialize in dermatological care. Among some of the many areas of concern patients present with in the clinic are skin tags.
Skin tags are a common occurrence which is associated with increased weight gain and having a genetic predisposition to developing them. They are generally harmless, and are as likely to occur in men as in women.  Sometime a skin tag (acrochordon is the medical term) can fall off spontaneously, and it is possible to never have known that it was there in the first place.
The most frequent places for skin tags to develop are in the places of the body where skin rubs against skin. These places are commonly the lower neck, the armpits, under the breasts in women, and in the groin area. Skin tags are usually relatively small, flat pieces of skin which hang from a thin stalk, usually not more than 2-5mm in diameter, flesh colored or sometimes a bit more brownish.
If a skin tag becomes irritated or a patient finds them unsightly or in any way annoying, it is possible to have it/them removed by a dermatologist like Dr. Larry Jaeger, in his office or clinic. They can be removed either by freezing, tying off with thread or suture, or cutting.
