I had a skin tag removed and it was a piece of cake! They are not usually cancerous either. I pointed mine out at a regular checkup with my family doctor. He called in a nurse, numbed the area, and cut the skin tag off. As with just about anything removed, it was sent to pathology but was, of course, benign. No stitches required, not even a bandage immediately after. It was very safe, painless, and quick.
Skin tags tend to crop up in places where there is rubbing or friction on the skin though they can appear anywhere. Again, they are almost always benign. I wouldn't hesitate to have one or more removed again. It's a very minor procedure.
