What Causes Skin Tags?
Skin tags are a common complaint.
In many cases, skin tags are believed to develop due to friction between adjacent areas of skin or between clothing and skin. Common sites for skin tags include the following:
Because of the increased skin-to-skin contact and friction, skin tags are more common in overweight obese people. Although skin tags can sometimes be seen in children, they tend to increase with age and are most common in middle-aged and older individuals.
Studies have suggested an inherited susceptibility to the development of skin tags. In people with Crohn's disease, skin tags around the anal opening (perianal skin tags) are common. The hormonal changes of pregnancy can also stimulate the growth of skin tags, particularly during the second trimester of pregnancy.Skin tags are not cancers. Reports of skin cancers arising in skin tags are extremely rare.
