I have a few "growths" (for lack of better term) in various places on my body. I had a dr look at a couple a very long time ago and he called them "skin tags" and said they just came with age on some people and were not dangerous unless they started growing weird and changing to dark colors. Well, now one has turned to a very dark color (it used to be my flesh color) but has not grown any. Should I be worried? I no longer have medication insurance so having a dr check it out is out of the question unless it's a dire emergency.
