It’s often disturbing and somewhat alarming to discover a new skin growth. Skin tags and cutaneous warts -- meaning nongenital warts -- are among the most common causes of new skin growths. Aesthetically unpleasant and sometimes uncomfortable, skin tags and warts share some similarities.

Skin tags, or acrochordons, are benign skin growths that project from the surrounding skin area and hang from a slender skin stalk. Skin tags are common, harmless and noncancerous; they may appear on the neck, under the arm pit, beneath the breast, on the back, chest or around the eyes.

Many of the home remedies used for removing skin tags may not be suitable for all areas of the body, particularly sensitive areas such as the armpits or groin.
